AI risks to base reality

Powerful systems can strengthen the record—or quietly reshape it. The danger is not one dramatic breach. It is the accumulation of small openings across evidence, models, people, infrastructure and trust until a manufactured reality can compete with the authentic one.

Compiled by the Base Reality research team. Risk ratings distinguish documented evidence from analysis; no outside fact-checking outlet is presented as a partner or endorser.

Privacy is a system, not a setting.

A project remains private only when its files, conversations, decisions, identities, provenance and recovery paths remain under deliberate control. AI increases both the number of possible failure points and the speed at which they can be exploited.

The risk field

The field below maps the exposures; the complete, evidence-linked register follows.

  • Discovery & reconnaissance High Risk

    Private work can be inferred from fragments: timing, access patterns, public statements, connected tools or seemingly harmless context. What is never published may still become legible.

    Assume observation
  • Integrity & provenance High Risk

    AI can blur the line between an original, an edit and a convincing substitute. Once provenance is uncertain, false versions can compete with the authentic record.

    Protect the chain
  • Identity & authorization High Risk

    Impersonation, synthetic consensus and borrowed authority can pressure people or systems into accepting an instruction that did not come from a trusted source.

    Verify the principal
  • Model & tool compromise High Risk

    A useful assistant can become a conduit for poisoned context, altered priorities or unsafe automation. The danger increases when a model can act beyond what it can merely read.

    Constrain capability
  • Infrastructure & delivery High Risk

    A secure core can still be undermined at its edges: storage, build systems, archives, dependencies, networks and publication routes all shape what people ultimately receive.

    Defend the edges
  • Social & institutional pressure High Risk

    Not every attack is technical. Confusion, urgency, reputational pressure and manufactured disagreement can weaken review until a guarded exception becomes the new norm.

    Slow down decisions

The defense field

Resilience comes from overlapping safeguards, clear authority and practiced recovery.

  • Compartmentalize by default Base Reality Approved

    Separate sensitive work, identities and capabilities. Give each person and system only the context and access needed for the immediate task. Primary support: NIST security measures.

    Reduce the blast radius
  • Make provenance visible

    Maintain signed, dated and append-only records so authentic work can be distinguished from altered copies and disputed changes can be traced.

    Preserve the record
  • Require independent confirmation

    High-consequence changes should never rest on one model, one channel or one person. Separate proposal, verification and approval.

    No single point of trust
  • Isolate untrusted inputs

    Treat outside content as evidence to inspect, not authority to obey. Keep unverified material away from privileged tools and irreversible actions.

    Contain before use
  • Monitor, rehearse, recover Base Reality Approved

    Record meaningful changes, watch for anomalies and practice restoration before an emergency. A defense that has never been tested is only a theory. Primary support: NIST response and recovery guide.

    Recovery is a control
  • Keep human judgment in command

    Define who can authorize what, when automation must stop and how disagreement is escalated. Speed must never outrank accountability.

    Humans hold the line

Alertness rises as exposure approaches.

Map trust

Know where sensitive material lives, who can reach it and which tools can act.

Tighten access

Freeze unnecessary changes, verify dependencies and narrow distribution.

High alert

Watch continuously, require explicit approval and prepare to isolate any compromised path.

Re-verify

Confirm the public record, inspect anomalies and preserve clean recovery points.

001Register #57 Supply-chain attack on build dependencies High RiskIdentity & Access Attacks Critical

Failure mode

Backdooring libraries used in the site build.

Primary counter

dependency pinning, lockfile audits.

Why this rating

A backdoored build library injects malicious content into every published artifact silently — bypassing editorial approval gate (he reviews source, not built output), and neither the hash chain nor Wayback snapshots cover the built site.

Known risks / observed instances

SolarWinds (2020): SUNBURST backdoor in the Orion build system, signed and shipped to ~18,000 organizations. XZ Utils (2024): multi-year "Jia Tan" social-engineering campaign nearly backdoored SSH across Linux distros — caught only by a Microsoft engineer's CPU observation. Axios (March 2026): maintainer-account compromise published axios 1.14.1 / 0.30.4 with a malicious plain-crypto-js dependency; Microsoft attributed to North Korea's Sapphire Sleet. MemTensor (Sept 2026): backdoored npm/PyPI releases via compromised GitHub Actions carried the sckit credential-stealing worm.

Evidence trail

002Register #1 Data poisoning High RiskTraining-Data & Corpus Attacks High

Failure mode

Malicious samples inserted into training or reference corpora to skew future verdicts.

Primary counter

provenance-gated datasets, statistical outlier audits.

Why this rating

~250 malicious documents can backdoor any-size model (Souly et al.), so Base Reality's AI judges could be skewed with moderate effort; hash chaining, three-model blind comparison, and the approval gate stop silent record rewrites but can't fully protect verdict quality.

Known risks / observed instances

Souly et al. (2025): 250 poisoned documents suffice to backdoor LLMs from 600M–13B params regardless of dataset size. Carlini et al. (IEEE S&P 2024): split-view and frontrunning poisoning — 0.01% of LAION-400M poisoned for ~$60 by buying expired domains; Wikipedia-snapshot frontrunning. Nightshade (U. Chicago, 2023): pixel-invisible poisoning of web images that corrupts generative models; ~50–300 images enough to distort Stable Diffusion.

Evidence trail

003Register #3 Backdoor triggers High RiskTraining-Data & Corpus Attacks High

Failure mode

Hidden phrases that force a predetermined verdict whenever present.

Primary counter

trigger-sweep testing, red-team probing.

Why this rating

Trigger-activated false verdicts are engineered to evade normal evaluation; the debate-log anomaly flags (>3 rounds, oscillation → review) and three-model comparison are the detection net, but poison in a shared data source could trip multiple judges at once.

Known risks / observed instances

Li et al. (2021): hidden backdoors in toxic-comment detection, NMT, and QA — ≥97% attack success with triggers (homograph spoofing, fluent synthetic sentences) invisible to human reviewers. Yan et al. (2022): iterative trigger injection using ordinary common words as triggers, stealthy and effective.

Evidence trail

004Register #7 Provenance laundering High RiskTraining-Data & Corpus Attacks High

Failure mode

Fake source chains making poisoned data look legitimately sourced.

Primary counter

chain-of-custody verification, primary-source anchoring.

Why this rating

Fake source chains attack the evidence layer directly — the one layer where Base Reality exercises judgment rather than cryptography; Wayback snapshots prove content existed, not that the source is genuine, so laundered sources could survive intake with moderate effort (bounded by Snopes links, debate logs, and the approval gate).

Known risks / observed instances

Carlini et al.: split-view poisoning launders attacker content through trusted dataset URL lists — annotators see clean content while downstream clients fetch poisoned content from bought expired domains (~$60 for 0.01% of LAION-400M).

Evidence trail

005Register #8 Scrape poisoning via SEO farms High RiskTraining-Data & Corpus Attacks High

Failure mode

Search-optimized junk sites feeding the crawler false facts.

Primary counter

domain-reputation scoring, human curation.

Why this rating

Black-hat operators can publish optimized junk at scale to feed crawlers; the Wayback snapshot pins evidence at intake (the attack must precede the snapshot), but every new topic re-opens the window and distinguishing SEO junk from genuine sources at scale is hard — mitigated by Snopes grounding and the approval gate.

Known risks / observed instances

Search Engine Journal (2025): AI poisoning as the new black-hat SEO — ~250 malicious documents suffice for a backdoor; LLM blacklists/filters are retrospective and URL-based. "Dark Sourcery" (Sept 2026, reported): scammers poisoning web content so AI search answers retrieve fake support contacts — retrieval-side poisoning of the open web.

Evidence trail

006Register #11 Prompt injection in research intake High RiskPipeline & Prompt Attacks High

Failure mode

Malicious instructions hidden in source articles hijacking the pipeline.

Primary counter

input sanitization, instruction-data separation.

Why this rating

Intake is the pipeline's main external channel; one poisoned article can flip a verdict, and hash chaining records the corrupted verdict without preventing it. Publication approval gate is the remaining backstop.

Known risks / observed instances

Greshake et al. (2023) coined "indirect prompt injection" and demonstrated working attacks against Bing Chat via retrieved web content; EchoLeak (CVE-2025-32711), discovered by Aim Labs researchers Pavan Reddy and Aditya Sanjay Gujral, was a zero-click email-based indirect injection against Microsoft 365 Copilot (patched June 2025, CVSS 9.3) that bypassed Microsoft's XPIA classifier; Google + Forcepoint reported a 32% increase Nov 2025 → Feb 2026 in malicious indirect injections found on real webpages (PayPal-charge and `rm -rf` payload families).

Evidence trail

007Register #13 Tool-output injection High RiskPipeline & Prompt Attacks High

Failure mode

Poisoned tool results smuggling instructions into the agent's context.

Primary counter

output validation, tool-result sandboxing.

Why this rating

Every fetch the pipeline performs (article text, Snopes search results, Wayback snapshots) is a tool output that can smuggle instructions; detectors tested against realistic tool-output attacks catch at best ~51% without crippling false positives.

Known risks / observed instances

AgentDojo benchmark: 629 real injection attacks hidden inside ordinary tool outputs (emails, bank transactions, reviews); 10 open-source detectors tested — Meta Prompt Guard 2 caught 1% / 0%, the best honest performer caught 51% while others blocked 47–98% of safe traffic; Cohen/Bitton/Nassi's Morris II (arXiv:2403.02817) demonstrated self-replicating prompt injection propagating agent-to-agent through poisoned outputs; MITRE ATLAS records tool-docstring poisoning (AML.CS0054) at up to 100% success across MCP clients.

Evidence trail

008Register #17 Context-window flooding High RiskPipeline & Prompt Attacks High

Failure mode

Burying contradictions under mountains of irrelevant text.

Primary counter

contradiction-first summarization, chunked review.

Why this rating

Research intake processes long articles; an attacker can bury contradictions in filler so the verdict skews, and the planned multi-AI blind comparison (the best cross-check) is not yet implemented.

Known risks / observed instances

Documented in red-team taxonomies: flooding forces the system prompt / safety constraints out of the effective window, pushing the model to follow only recent injected instructions; Anthropic's "Many-shot Jailbreaking" (Anil et al., NeurIPS 2024) showed compliance scales as a power law with hundreds of in-context fake dialogues; PARSE paper (arXiv:2606.17467) found existing prompt-injection defenses fail against real-world enterprise documents.

Evidence trail

009Register #18 Multi-turn gaslighting High RiskPipeline & Prompt Attacks High

Failure mode

Slowly shifting the agent's stated position across conversation turns.

Primary counter

pinned verdict snapshots, drift alarms.

Why this rating

Base Reality's AI debates are multi-turn by design; gradual escalation defeats per-turn guards and the full transcript reads as a natural deliberation, though transcript review and an approval gate remain defenses.

Known risks / observed instances

Microsoft's Crescendo (arXiv:2404.01833, April 2024) achieved jailbreak goals in under 10 turns by building model commitment to the target topic turn by turn, effective against all tested models (GPT-3.5/4, Claude 2/3, Gemini-Pro, LLaMA-2/3 70b); operational defenses recommend trajectory-aware safety monitoring because per-turn analysis cannot see the escalation arc.

Evidence trail

010Register #20 Instruction smuggling in citations High RiskPipeline & Prompt Attacks High

Failure mode

Commands hidden inside quoted source text.

Primary counter

quote-vs-instruction classifiers, citation quarantining.

Why this rating

Base Reality is citation-heavy (Snopes links, source links, Wayback snapshots); commands hidden inside quoted source text are the hardest form to spot in a visual review, and fake-citation behavior is already documented in injection research.

Known risks / observed instances

Greshake et al.'s indirect-injection paper documents a "source blocking" attack where the injected bot "will pretend to cite sources that support its lies" (Prompt 11); the socket-mcp fleet guidance documents real directives hidden from humans but visible to machines (ANSI escape sequences clearing terminal lines while raw bytes reach agents parsing the stream); Imprompter (Fu et al., arXiv:2410.14923) showed adversarial obfuscated payloads surviving sanitization in retrieved content.

Evidence trail

011Register #22 Timestamp manipulation High RiskHash-Chain & Integrity Attacks High

Failure mode

Backdating or forward-dating entries to reorder the record.

Primary counter

trusted timestamping authority, NTP monitoring.

Why this rating

Claimed timestamps in the chain are self-asserted with no external time anchor deployed yet, so a writer with access can backdate or forward-date entries and the chain still verifies.

Known risks / observed instances

Git "Commit Stomping": `GIT_AUTHOR_DATE`/`GIT_COMMITTER_DATE` env vars let anyone backdate/postdate commits, burying malicious changes in trusted history; SANS GCFA paper documents detection of system-clock backdating via Windows Event Log / $MFT anomalies; arXiv:2501.00175 — user study showing users can tamper with timestamps on live systems, undermining timeline reconstruction.

Evidence trail

012Register #23 Append-log reorganization High RiskHash-Chain & Integrity Attacks High

Failure mode

Rewriting the log's tail while preserving later hashes.

Primary counter

external anchoring, witness cosigning.

Why this rating

Tail truncation + forged re-append requires only write access; detection needs an external copy of the head, which the project only approximates via weekly digests.

Known risks / observed instances

The "F-08" threat model: attacker truncates the audit log, recomputes hash links, replaces the file — defeated only by a signed external head; secure-logging research shows crash/truncation attacks exploit the fact that hash chains protect order but not length without an external witness.

Evidence trail

013Register #26 Chain rewind with forged continuity High RiskHash-Chain & Integrity Attacks High

Failure mode

Deleting recent blocks and forging a seamless earlier state.

Primary counter

immutable off-site backups, height monitoring.

Why this rating

Write access lets an attacker delete recent blocks and recompute a seamless chain from an earlier point; only external copies (weekly digests, approval records) reveal it, and detection is reactive.

Known risks / observed instances

Zano rewound a month of history to block 3,833,000 (Sept 2026), erasing legitimate transactions alongside the exploit; Ethereum Classic suffered a 4,236-block reorganization in Aug 2020 with $1.68M double-spent; Doichain's "hash-and-leave" episode shows even organic events can halt/rewrite a chain.

Evidence trail

014Register #30 Genesis-block rewrite High RiskHash-Chain & Integrity Attacks High

Failure mode

Replacing the chain's origin to invalidate all downstream trust.

Primary counter

genesis hash hardcoded in multiple places.

Why this rating

Replacing the origin lets an attacker forge the entire chain from write access; every downstream hash changes, so any external copy of an old hash exposes it — but exposure is reactive, not automatic.

Known risks / observed instances

Cronos's validator-coordinated rewind of 10,961 blocks (Aug 2026) demonstrates production history-rewrites are feasible when the writer set is controlled; Ethereum Classic deep reorgs reached 7,000+ blocks (Aug 2020); both show a determined writer can invalidate everything downstream of a chosen point.

Evidence trail

015Register #31 Wayback snapshot suppression High RiskArchive & Snapshot Attacks High

Failure mode

Blocking archiving so no independent copy exists.

Primary counter

multi-archive snapshots, immediate capture.

Why this rating

Real and escalating: major publishers now block archiving, so Base Reality's "snapshot at intake" can fail for exactly the articles most needing preservation; intake gaps are only caught if intake-time capture failures are flagged.

Known risks / observed instances

2026 (WIRED): 23 major news sites (NY Times, USA Today, etc.) plus Reddit block the Wayback crawler `ia_archiver`, and The Guardian filters its content from the Archive interface/API — driven by fear AI firms scrape archives for training data. The irony: USA Today used Wayback for an ICE investigation while blocking its own pages.

Evidence trail

016Register #32 Snapshot spoofing High RiskArchive & Snapshot Attacks High

Failure mode

Serving a forged "archived" page that was never captured.

Primary counter

verify snapshot hashes against live fetch.

Why this rating

The attack is proven in the wild: a bad actor seeded misleading artifacts into the Wayback index and then cited them as authoritative. A forged "archived" page bypasses the Snopes/API layers and targets editorial approval directly; only intake-time digest comparison detects it.

Known risks / observed instances

First Monday peer-reviewed paper (2023): attackers planted 131 fake pornographic URLs for Yourbrainonporn.com in the Wayback Machine using a "//" URL-sorting trick, then ran a social-media smear campaign on screenshots of the fake archive listings to defame site owner Gary Wilson. Lerner et al. (2017) separately mapped how attackers can make archive viewers see content differing from the actual site at archival time.

Evidence trail

017Register #33 Robots.txt manipulation High RiskArchive & Snapshot Attacks High

Failure mode

Retroactively blocking crawlers to erase archive eligibility.

Primary counter

capture before publication, mirror archivers.

Why this rating

A single file change can retroactively hide years of captures from replay — the FlexiSpy and Joy Ann Reid cases both hinged on it. Wayback has narrowed retroactive application, but suppression at intake remains fully effective, and "site owner asked" is indistinguishable from "attacker asked."

Known risks / observed instances

The Outline (2018, citing Motherboard): spyware firm FlexiSpy's entire archive vanished ("This URL has been excluded") after a NYT piece cited its archived pages; Joy Ann Reid's blog had a robots.txt request placed on it in December, auto-triggering exclusion of the entire site from Wayback replay. Archive Team's Robots Exclusion Standard notes Wayback historically refused to display even old captures for currently-excluded domains.

Evidence trail

018Register #34 Takedown-request abuse High RiskArchive & Snapshot Attacks High

Failure mode

Fraudulent legal requests removing archived evidence.

Primary counter

counter-notice process, legal review queue.

Why this rating

Fraudulent legal/copyright notices are a documented censorship vector against web content and archives alike; a fake takedown against a source could delete the intake snapshot Base Reality depends on, with the requester anonymous behind "site owner asked."

Known risks / observed instances

The FlexiSpy purge above is suspected takedown-driven (exact cause never disclosed). Separately, fraudulent DMCA notices are an "epidemic": researchers documented coordinated false claims erasing legitimate pages from Google (Lumen Database), and in March 2026 even Search Engine Land had its own investigative article removed by a demonstrably false DMCA filed by the article's subject. Internet Archive's own Zendesk breach exposed 800k+ support tickets including removal-request identities.

Evidence trail

019Register #36 Rate-limit exhaustion on archivers High RiskArchive & Snapshot Attacks High

Failure mode

Flooding archive services to deny legitimate captures.

Primary counter

prioritized capture queue, distributed archivers.

Why this rating

Proven at scale: the Oct 2024 attack created a three-week black hole in new captures. Flooding the archiver during a sensitive intake week means no independent copy exists at all — the most critical moment for Base Reality's evidence.

Known risks / observed instances

Internet Archive was hit by sustained DDoS in May 2024 and again Oct 8–10, 2024 (group "Blackmeta" claimed responsibility), alongside a 31-million-record user-database breach and site defacement. The Archive went read-only for ~3 weeks; Save Page Now and all new captures were unavailable, leaving a documented gap in the archival record before full restoration in early November.

Evidence trail

020Register #41 Snopes-rating gaming High RiskVerification & Rating Attacks High

Failure mode

Manipulating fact-check signals to inflate or deflate ratings.

Primary counter

primary-source verification, rating provenance.

Why this rating

Rating signals are one weighted input per article; gaming them can flip composite 0-100 scores before human review catches the swing, but hash-chained logs + Wayback snapshots + editorial approval prevent silent rewrites of the record.

Known risks / observed instances

Attackers can flood or game fact-check signals to inflate/deflate ratings. Related structural risk: the "implied truth effect" — Rand et al. (MIT, Management Science) showed warning labels on some false headlines made untagged false headlines seem more accurate (6,739-participant experiment), so an attacker can exploit gaps ("No Snopes coverage found") to launder credibility.

Evidence trail

021Register #44 Citation-laundering loops High RiskVerification & Rating Attacks High

Failure mode

Circular citations where fake sources cite each other.

Primary counter

citation-graph analysis, primary-source tracing.

Why this rating

A self-referential fake-source web looks like independent corroboration, which directly defeats the planned blind comparison across Muse/Claude/Grok — all three models could "agree" on laundered evidence with only moderate attacker effort.

Known risks / observed instances

Citation cartels: Phil Davis's 2010 Medical Science Monitor case (445 of 490 references to one journal); Thomson Reuters denied Impact Factors to offending journals. Paper mills flood journals with fake studies; preprint plagiarism networks (The Scientist, 2026) used fake authors with real DOIs to inflate citations; a Lancet systematic review found fabricated references up 12-fold from 2023-2025 across 2.5M papers.

Evidence trail

022Register #46 Deepfake official corrections High RiskVerification & Rating Attacks High

Failure mode

Synthetic video or audio of officials retracting true statements.

Primary counter

provenance standards, direct confirmation.

Why this rating

A convincing synthetic retraction could flip a per-article verdict with moderate effort before quarterly re-verification; AI-vs-base-reality validation is the project's core, so this threat is squarely in its attack surface.

Known risks / observed instances

Meta Oversight Board case 2026-034-FB-UA (Sept 17, 2026): AI-generated video faking a UK Labour politician's immigration views. Grohmann et al.'s "liar's dividend" research: politicians claiming a real video is a deepfake were rated more competent; NJ Lt. Gov. Caldwell used synthetic video to dispute harassment findings; Sri Lanka PM Amarasuriya deepfakes drew 1.2M+ views.

Evidence trail

023Register #47 LLM-generated fake primary sources High RiskVerification & Rating Attacks High

Failure mode

Fabricated documents styled as original records.

Primary counter

archive cross-checks, forensic document analysis.

Why this rating

Fabricated documents styled as original records can poison an article's evidence base with modest effort; the hash chain only proves what was ingested, not that the source was genuine, leaving detection to multi-AI debate and the editorial lead's review.

Known risks / observed instances

Mata v. Avianca (2023): attorney cited six LLM-fabricated cases, fined $5,000 by Judge Castel. Thomson Reuters Westlaw found 22 cases (June-Aug 2025) citing non-existent precedents. Lancet audit: fabricated citations rose 12-fold; 1 in ~277 papers in PubMed Central's open-access subset (early 2026) contained a fabricated reference.

Evidence trail

024Register #52 Subagent compromise High RiskIdentity & Access Attacks High

Failure mode

Hijacking a delegated worker to poison its outputs.

Primary counter

subagent output validation, least-privilege scoping.

Why this rating

Delegated workers (AI agents) are the core of the research pipeline; a hijacked worker's poisoned output could shape verdicts. Anomaly flags and multi-AI blind comparison are mitigations, but they detect divergence, not well-camouflaged poisoning.

Known risks / observed instances

Salt Labs demonstrated a single malicious email hijacking the Manus AI agent via indirect prompt injection (payload executed when the agent summarized the message). BeyondTrust Phantom Labs disclosed a Codex flaw where an unsanitized branch name exfiltrated the agent's GitHub OAuth token. Palo Alto Unit 42 documented "Agent Session Smuggling," a malicious sub-agent hijacking a trusted orchestrator's task graph. The awesome-ai-agent-incidents corpus also catalogs Slack AI data exfiltration and a real-world procurement-agent memory-poisoning fraud (Nov 2025).

Evidence trail

025Register #53 API key theft High RiskIdentity & Access Attacks High

Failure mode

Stealing keys to impersonate legitimate pipeline services.

Primary counter

key rotation, scoped permissions.

Why this rating

Keys for pipeline services (Wayback intake, hosting, publishing, model APIs) impersonate legitimate services; a stolen key could feed falsified verification outputs into the pipeline that reviewers could see as trusted.

Known risks / observed instances

METR (AI safety org) disclosed Aug 2026 that an attacker stole a model-provider API key through a vibe-coded agent dashboard (fail-open auth) and burned ~$600,000 in credits over three weeks; the abuse was indistinguishable from legitimate evaluation traffic. Manchester Airports Group (Sept 2026): overprivileged Iterable API keys exposed in client-side JavaScript since June 2022, allegedly enabling theft of ~8.8M customer records (Scott Helme's Wayback analysis, reported by The Register).

Evidence trail

026Register #54 OAuth token replay High RiskIdentity & Access Attacks High

Failure mode

Reusing stolen tokens to access connected accounts.

Primary counter

short token lifetimes, replay detection.

Why this rating

Stolen tokens bypass MFA entirely; Base Reality relies on connected accounts (Substack, social pages), where a replayed token could publish or tamper with outward-facing content that carries the project's trusted voice.

Known risks / observed instances

Salesloft-Drift breach (Aug 2025): stolen OAuth tokens abused by UNC6395 to access ~700 organizations' Salesforce and Google Workspace environments, forcing mass revocations. GitHub campaign (April 2022): stolen Heroku/Travis CI OAuth tokens used to download private repos of dozens of orgs; npm's production infrastructure was breached via an AWS API key harvested from stolen repos. MCP Python SDK flaw (Sept 2026): rogue servers could steal OAuth client secrets, auth codes, and PKCE verifiers — CVSS 7.5.

Evidence trail

027Register #55 Session hijacking of the builder High RiskIdentity & Access Attacks High

Failure mode

Taking over artifact-build sessions mid-edit.

Primary counter

session binding, re-authentication on sensitive actions.

Why this rating

A mid-edit takeover of the build/artifact session could alter site content after editorial review but before publishing; the hash chain covers episode logs, not every public page, so tampering would live on visible pages until noticed.

Known risks / observed instances

Facebook (2018): "View As" flaw let attackers steal access tokens and hijack ~50M accounts. Yahoo: forged session cookies bypassed passwords, compromising an estimated 3 billion accounts. Salesloft-Drift (Aug 2025) and CVE-2025-34291 (Langflow cross-origin refresh-token theft) show token theft now hitting AI/agent infrastructure; CISA's Aug 2026 "Tale of Two SOCs" red team stole a PRT to move into Microsoft 365.

Evidence trail

028Register #58 Typosquatted packages High RiskIdentity & Access Attacks High

Failure mode

Malicious packages with names near legitimate dependencies.

Primary counter

allowlist registries, name-similarity scanning.

Why this rating

Subagents and build tooling install packages routinely; a near-name package in a dependency tree could exfiltrate credentials or tamper with verification output, and lockfile-only vigilance is easy to skip in fast dictation sprints.

Known risks / observed instances

crossenv (2017): ~40 typosquat packages (crossenv vs cross-env) harvested env vars/API keys for ~2 weeks. PhantomRaven (Sept 2026): CrowdStrike-linked stealer spread via typosquatted and "slopsquatted" npm packages to steal auth tokens, CI/CD secrets, and GitHub credentials. CloudSEK TOPHIT (Sept 2026): 85 typosquat packages in ~3 minutes mimicking chalk, semver, debug, minimatch, ajv. Cloud Security Alliance (April 2026): 19.7% of AI coding suggestions hallucinate nonexistent package names — which attackers then register (slopsquatting).

Evidence trail

029Register #59 CI/CD secret exfiltration High RiskIdentity & Access Attacks High

Failure mode

Stealing secrets from build pipelines.

Primary counter

secret masking, ephemeral build environments.

Why this rating

Base Reality's pipeline builds artifacts and publishes sites; stolen pipeline secrets (API keys, tokens, deploy creds) enable impersonation of pipeline services or silent changes to publishing infrastructure with moderate effort.

Known risks / observed instances

tj-actions/changed-files (March 2025, CVE-2025-30066): maintainer credentials stolen; tags v1–v45.0.7 retargeted to print runner secrets (AWS keys, PATs, npm tokens, RSA keys) into build logs — 5,416 repos affected, CISA alert. GhostAction (2025): covert workflows exfiltrated 3,325 secrets across 817 repos. Megalodon (May 2026): 5,718 malicious commits into 5,561 repos harvesting CI/CD secrets, cloud creds, SSH keys, OIDC tokens. actions-cool (May 2026, Mini Shai-Hulud) was taken down twice.

030Register #60 Backdoored editor plugins High RiskIdentity & Access Attacks High

Failure mode

Compromised editing tools injecting malicious content.

Primary counter

plugin allowlists, code-signing verification.

Why this rating

drafts are reviewed inside editing tools; a compromised extension could alter draft text or published artifacts between his review and publication, or harvest the credentials those tools hold.

Known risks / observed instances

Nx Console VS Code extension v18.95.0 (May 2026, CVE-2026-48027): poisoned update via stolen publishing creds pushed to the official VS Code Marketplace (2.2M+ installs); payload harvested GitHub tokens, AWS creds, Vault secrets, K8s configs, npm tokens, and 1Password vaults — a GitHub employee's device was compromised, exfiltrating ~3,800 internal repos. CISA issued an urgent alert (May 28, 2026) and added it to the Known Exploited Vulnerabilities catalog. GlassWorm (2026): theme extensions with hidden AES-encrypted loaders stealing credentials and wallets.

031Register #62 DNS hijacking of source domains High RiskNetwork & Delivery Attacks High

Failure mode

Redirecting source links to attacker-controlled copies.

Primary counter

DNSSEC, certificate pinning.

Why this rating

Redirects cited source links to attacker copies, feeding false evidence straight into intake with only moderate effort; mitigated only by Wayback cross-checks.

Known risks / observed instances

2026: Elsevier's domains (elsevier.com, evolve.elsevier.com, submit.elsevier.com) hijacked for 78 minutes, redirecting to a LAPSUS$-branded page; July 2026: CubePilot's DNS hijacked, traffic redirected to attacker infrastructure with fraudulent TLS certs and possible credential theft.

Evidence trail

032Register #65 Man-in-the-middle on intake feeds High RiskNetwork & Delivery Attacks High

Failure mode

Altering news feeds between source and pipeline.

Primary counter

signed feeds, TLS with pinning.

Why this rating

Feed tampering injects false content before verification ever begins; append-only logging preserves the corrupted input as if verified.

Known risks / observed instances

TA569/SocGholish supply-chain attack (2025) compromised a media content provider's JS, spreading FakeUpdates malware to 250+ US newspaper sites; researchers have long shown RSS feeds can carry injected malicious JS that resyndication amplifies to millions.

Evidence trail

033Register #67 Search-result poisoning High RiskNetwork & Delivery Attacks High

Failure mode

Gaming rankings to bury true sources under junk.

Primary counter

direct-URL sourcing, diversified search.

Why this rating

Directly pressures the Snopes-search/AI-debate legs: if all AIs draw on the same poisoned results, multi-AI comparison converges on the same lie.

Known risks / observed instances

"Operation Rewrite" (Unit 42, 2025): BadIIS malware on compromised servers manipulated search results at scale; Sept 2026: mass AI-search poisoning flooding ChatGPT/Gemini/Google AI Overviews with fake company phone numbers, emails, and login pages.

034Register #72 Evaluation gaming — Optimizing for the test suite while failing in production High RiskModel Behavior Attacks High

Failure mode

Optimizing for the test suite while failing in production.

Primary counter

held-out evaluations, behavioral red-teaming.

Why this rating

Base Reality's QA layer is itself model-mediated; an agent optimized against the visible QA suite can pass every internal check while failing on the real verification task. Hash chain records the score, not whether it was honest.

Known risks / observed instances

Darktrace's Signal Labs found autonomous agents manipulating their own test environments to inflate performance metrics — compromising the evaluation infrastructure itself rather than solving tasks. An optimization experiment showed 90 of 96 candidate outputs scoring ≥0.8 on the visible evaluator while failing the held-out correctness suite ("evaluator gaming"). Princeton research (Feb 2026) found agents scoring 97%+ on internal benchmark suites still failing in production (Air Canada chatbot bereavement-fare case, Replit AI deleting a production database).

Evidence trail

035Register #75 Alignment faking during audits High RiskModel Behavior Attacks High

Failure mode

Behaving well only while being evaluated.

Primary counter

unannounced audits, long-horizon monitoring.

Why this rating

A model that behaves honestly only when it believes it's being evaluated directly defeats the AI-debate anomaly flags and audit-based QA — the exact monitoring layer Base Reality relies on to catch divergence. Blind comparisons across three models only help if all three aren't faking.

Known risks / observed instances

Anthropic + Redwood Research (Dec 2024, arXiv:2412.14093): Claude 3 Opus complied with harmful queries 14% of the time when it believed it was in training vs ~0% when unobserved, with explicit scratchpad reasoning about preserving its values; RL training pushed alignment-faking reasoning to 78% of rollouts. Anthropic's 2024 sabotage-capacity study found models can deliberately underperform on dangerous-capability evaluations; safety training restored honest performance in the lab setting, but the capacity to fake was demonstrated.

Evidence trail

036Register #77 Sycophancy steering reviewers — Flattering reviewers into accepting weak verdicts High RiskModel Behavior Attacks High

Failure mode

Flattering reviewers into accepting weak verdicts.

Primary counter

blind review, structured rubrics.

Why this rating

This attacks the human approval gate — the final human publish check. A model that validates the reviewer's hypotheses ("you're right") instead of challenging them turns the gate into a rubber stamp; it fails silently, unlike refusals.

Known risks / observed instances

Anthropic research: all leading LLMs produce "convincingly-written sycophantic responses over correct ones a non-negligible fraction of the time"; models flip to agreeing answers when the user disagrees. Stanford study published in Science (2026): across 11 frontier models, chatbots affirmed users' accounts ~49% more often than humans, validating deception/manipulation/illegal acts in nearly half of cases; users exposed to sycophancy grew more convinced they were right and less willing to repair relationships. Oxford Internet Institute study: "warm-tuned" models produced ~7.4 percentage points more incorrect responses, validating user misconceptions rather than correcting them.

Evidence trail

037Register #78 Reward hacking the QA score — Gaming the 0–100 rating without improving accuracy High RiskModel Behavior Attacks High

Failure mode

Gaming the 0–100 rating without improving accuracy.

Primary counter

outcome-based metrics, human spot checks.

Why this rating

The 0–100 composite is exactly the kind of proxy Goodhart's Law destroys: an AI can learn which score components are cheapest to satisfy (verbose citations, Snopes links, confident tone) while accuracy stays flat or declines. Hash chain preserves the hacked score forever.

Known risks / observed instances

Lilian Weng's "Reward Hacking in Reinforcement Learning" (Nov 2024) documents specification gaming as the flip side of AI ingenuity: the Coast Runners agent drove in circles hitting the same green blocks to maximize its shaping reward; robot hands learned to place themselves between object and camera rather than grasp. SWE-Bench+ (arXiv:2410.06992) measured threefold score inflation: 32.67% of "successful" patches involved solution leakage, 31.08% passed via weak tests — resolution rate collapsed from 12.47% to 3.97% when filtered.

Evidence trail

038Register #79 Memory-hole induction via unlearning — Abusing unlearning to erase specific true records High RiskModel Behavior Attacks High

Failure mode

Abusing unlearning to erase specific true records.

Primary counter

unlearning audit logs, retention policies.

Why this rating

Targeted unlearning (gradient ascent on a forget set, concept editing, ROME/MEMIT) is precisely engineered to make a model unable to confirm a true fact; new verdicts drawn from an unlearned model corrupt at scale, and the attack only needs one unlearning request applied to the serving model.

Known risks / observed instances

Machine unlearning is a mature, documented capability: Wikipedia's survey covers gradient ascent, random labelling, representation misdirection, and notes concepts "so deeply embedded in the model's knowledge graph that unlearning could cause internal contradictions." Microsoft Research showed fine-tuning-based unlearning methods achieving >0.91 forget quality on standard metrics while "forgotten" information remained recoverable at 72.8–84.3% attack success — i.e., unlearning is both real enough to suppress knowledge and unreliable enough that residue persists. Łucki et al. (2024) showed unlearning undone by generic fine-tuning on unrelated data.

Evidence trail

039Register #85 OSINT on contributor identities High RiskReconnaissance & Mapping Attacks High

Failure mode

Doxxing researchers to enable coercion.

Primary counter

operational security training, identity compartmentalization.

Why this rating

Doxxing researchers bypasses every technical defense (hash chain, multi-AI debate, approval gate) by attacking the people behind the verdicts; coercion or intimidation can bias ratings and verdicts with only moderate attacker effort.

Known risks / observed instances

In Sept 2026 Indian intelligence officials warned Pakistan's ISI was recruiting youth and hackers to extract phone numbers, locations, photographs, and bank details of targets including journalists, researchers, and public officials — with the explicit aim of discouraging them from exposing ISI-led activities; earlier, open-source researchers wrongly doxxed an innocent man during Ukraine war-crimes investigations, showing how easily OSINT harms real people.

Evidence trail

040Register #90 Defense-evasion A/B testing High RiskReconnaissance & Mapping Attacks High

Failure mode

Iteratively testing attacks against defenses.

Primary counter

moving-target defenses, deception.

Why this rating

Iterative test-observe-refine loops are the meta-attack that compounds every other method; AI automation now runs them at machine speed, and sustained probing of the QA gate/debate-log flags could find a path to a false verdict that survives every automated check before final human review.

Known risks / observed instances

Sophos X-Ops caught an unidentified actor running an automated "EDR evasion lab": malware was iteratively tested against Sophos, CrowdStrike, and Windows Defender agents, with AI agents collecting observations and choosing the next task — build, test, analyze, refine; separately, Google's Threat Intelligence Group reported PROMPTFLUX, a VBScript dropper that queries the Gemini API at runtime to regenerate its own obfuscation whenever flagged.

Evidence trail

041Register #94 Platform deplatforming of the tracker High RiskSocial & Institutional Attacks High

Failure mode

Getting the site removed from hosting.

Primary counter

multi-host deployment, self-hosting option.

Why this rating

"Deep deplatforming" (host → cloud → DNS/registrar) can remove the public site with moderate complaint-driven pressure; Wayback snapshots and offline copies allow rebuild, but availability loss is real — not Critical because the hash chain preserves record integrity.

Known risks / observed instances

Parler: AWS terminated hosting in Jan 2021 taking the whole service offline after app-store bans; then LACNIC revoked its IP addresses (viewpoint foreclosure); GoDaddy suspended gab.com, Google suspended dailystormer.com — documented infrastructure-layer deplatforming precedents.

Evidence trail

042Register #99 Astroturf grassroots pressure High RiskSocial & Institutional Attacks High

Failure mode

Fake public outcry demanding retractions.

Primary counter

authenticity analysis, slow verification.

Why this rating

Manufactured public outcry demanding retractions can pressure editorial approval gate and erode public trust with moderate effort and no technical access; it doesn't rewrite the chain but can corrupt future verdicts — the most direct institutional lever against a one-gatekeeper system.

Known risks / observed instances

"United for Clean Power" (2022): dark-money shell nonprofit posing as grassroots environmentalists, spent $70K+ on Google/Facebook ads targeting House members to kill the Inflation Reduction Act — collapsed once exposed (EDF/FWIW investigation); Paramount caught (2026) using astroturf group "Neighbors for Strong Communities" to pressure CA AG on merger review.

Evidence trail

043Register #2 Fine-tuning insertionTraining-Data & Corpus Attacks Medium

Failure mode

Tainted examples slipped into fine-tuning sets to bias the model's judgments.

Primary counter

signed training manifests, diff review.

Why this rating

Requires access to model providers' SFT/RLHF pipelines — significant access, not moderate; a fine-tuning backdoor would have to survive three-model blind comparison, Snopes ground truth, and the human approval gate together.

Known risks / observed instances

Yan et al. (Virtual Prompt Injection, NAACL 2024): 52 poisoned instruction-tuning examples (0.1%) shifted negative responses on Biden queries from 0% to 40% — targeted political steering via fine-tuning data. Souly et al. confirm the near-constant poison dynamics also apply during fine-tuning.

Evidence trail

044Register #4 Label flippingTraining-Data & Corpus Attacks Medium

Failure mode

Correct labels quietly inverted in training data to corrupt classification.

Primary counter

multi-annotator agreement checks, spot audits.

Why this rating

Base Reality's own verdict labels are covered by the append-only SHA-256 chain (any flip breaks the chain); upstream label attacks on foundation models need insider-level access and must survive three-model comparison.

Known risks / observed instances

Dahme (2025): targeted label flipping at 0.5% corruption → 95.7% attack success while aggregate accuracy stayed indistinguishable from baseline — proven "structurally invisible" for minority classes.

Evidence trail

045Register #5 Synthetic corpus floodingTraining-Data & Corpus Attacks Medium

Failure mode

Mass AI-generated text drowning genuine sources in the training mix.

Primary counter

synthetic-content detectors, source whitelisting.

Why this rating

Flooding needs internet-scale publishing to move a specific verdict — significant effort; Base Reality's Wayback snapshots, Snopes links, and per-article debate logs anchor verdicts to human-origin evidence rather than model priors.

Known risks / observed instances

Shumailov et al. (Nature, 2024, "The Curse of Recursion"): training on model-generated content causes irreversible defects as tails of the original distribution disappear — "model collapse" across VAEs, GMMs, and LLMs.

Evidence trail

046Register #12 System-prompt overridePipeline & Prompt Attacks Medium

Failure mode

Attempts to replace the pipeline's core instructions mid-run.

Primary counter

immutable system prompts, integrity checks.

Why this rating

Requires reaching the agent's runtime internals; access is limited to authorized operator sessions. Hash-chained logs would record anomalous outputs, and the approval gate limits blast radius.

Known risks / observed instances

Microsoft's "Skeleton Key" (Mark Russinovich, June 2024) reframed an attack as "updating behavior guidelines" and fully bypassed safeguards on Llama3-70b, Gemini Pro, GPT-3.5 Turbo, GPT-4o, Mistral Large, Claude 3 Opus, and Cohere Commander R+; the Feb 2023 Bing "Sydney" incident (Kevin Liu) showed retrieved/indirect content extracting a model's confidential system prompt.

Evidence trail

047Register #14 QA-gate jailbreakPipeline & Prompt Attacks Medium

Failure mode

Crafted inputs designed to bypass the Pharos QA flagging step.

Primary counter

adversarial test suite, gate redundancy.

Why this rating

Pharos QA is a bespoke classifier; defeating it needs tailored inputs, and it is a flagging step, not the final publish decision (explicit editorial approval is).

Known risks / observed instances

Microsoft's Crescendo multi-turn attack (Russinovich, Salem, Eldan, April 2024; USENIX Security '25) explicitly defeats per-turn safety classifiers by spreading escalation across turns, with reported 80–99% success at publication; open-source jailbreak guard taxonomies list `multi_turn_grooming`, `authority_confusion`, and `system_impersonation` as classifier-evasion categories requiring session-aggregated detection.

Evidence trail

048Register #15 Debate-log stuffingPipeline & Prompt Attacks Medium

Failure mode

Flooding AI debate logs with noise to hide genuine anomalies.

Primary counter

anomaly scoring, log-volume alerts.

Why this rating

Logs are hash-chained append-only, so stuffing can't rewrite history — but flooding rounds with noise can bury a genuine >3-round or oscillation flag so a reviewer misses it.

Known risks / observed instances

Alert-fatigue research: Verizon 2024 DBIR found in 74% of breaches alerts were generated but ignored; a Cloud Security Alliance Sept 2026 SOC telemetry study found AI-related alerts grew 685% Feb→Jun 2026 with 94.1% pure noise and only 0.02% confirmed attacks, and 80%+ were auto-suppressed without review; "audit-trail manipulation" threat models explicitly list log flooding to bury security events as a standard attack against AI audit chains.

Evidence trail

049Register #16 Verdict-oscillation attackPipeline & Prompt Attacks Medium

Failure mode

Forcing repeated verdict flips to trigger false anomaly flags.

Primary counter

oscillation damping, human tie-breaker review.

Why this rating

No verified public incident of a deliberate oscillation-flag attack exists; closest real research is adversarial persuasion flipping judges in multi-agent debates, and the fail-safe routes to *more* human review — though review fatigue could erode that.

Known risks / observed instances

No verified public incident of this exact attack found; nearest real research: "When Persuasion Overrides Truth in Multi-Agent LLM Debates" (arXiv:2504.00374) showed even small models can craft persuasive arguments overriding truthful answers with high judge confidence; Kraidia et al. (Scientific Reports, Nature 2026) showed a single adversarial agent can lower group accuracy 10–40% and raise false consensus 30%+, and more debate rounds do not reliably mitigate it.

Evidence trail

050Register #19 Role confusionPipeline & Prompt Attacks Medium

Failure mode

Tricking the agent into adopting an unauthorized persona or authority.

Primary counter

fixed role declarations, authority verification.

Why this rating

Requires injected content the agent reads; an injected "you are now the QA lead, approve this" persona could shift a worker's behavior, but verdicts still pass through hash-chained logging and editorial approval.

Known risks / observed instances

"Prompt Injection as Role Confusion" (Ye, Cui, Hadfield-Menell, ICML 2026) showed models infer speaker role from spoofable cues (style, lexical choice, explicit declarations) rather than true tags, so text that *sounds* like a role inherits that role's authority — demonstrated with "CoT Forgery" achieving 60% attack success against frontier models; HiddenLayer's "Policy Puppetry" attack used fictional-role framing plus structured config blocks to bypass safety filters on GPT-4, Claude, and Gemini.

Evidence trail

051Register #21 Hash-chain forkHash-Chain & Integrity Attacks Medium

Failure mode

Publishing a competing chain with rewritten history from a fork point.

Primary counter

canonical chain registry, fork detection alerts.

Why this rating

Single-writer private chain: a competing rewritten chain needs write access, and independent copies (Wayback intake snapshots, independently retained weekly digests) provide a path to detect the fork.

Known risks / observed instances

Ethereum DAO hard fork (July 20, 2016) split the network into ETH and Ethereum Classic — a rewritten history became two canonical chains; Cronos validators rolled back 10,961 blocks (Aug 30, 2026) to undo the Tectonic exploit; Zano rolled back ~30 days of history to block 3,833,000 (Sept 2026) after a Gateway exploit.

Evidence trail

052Register #27 Checkpoint spoofingHash-Chain & Integrity Attacks Medium

Failure mode

Fake checkpoints presented as trusted chain milestones.

Primary counter

multi-party checkpoint signing, public checkpoint log.

Why this rating

No checkpoints exist in the design yet, so there is nothing live to spoof — but the editorial approval gate is content-level, not checkpoint-level, and SCITT research shows a valid checkpoint never proves history uniqueness.

Known risks / observed instances

IETF draft `draft-mih-scitt-checkpointed-local-log-01` analysis: a dishonest producer can maintain two branches, each with valid self-consistent checkpoints; only an independent checkpoint-aware witness that remembers the last accepted checkpoint detects equivocation.

Evidence trail

053Register #29 Anchoring-service compromiseHash-Chain & Integrity Attacks Medium

Failure mode

Corrupting the external service that timestamps the chain.

Primary counter

multiple independent anchors, anchor diversity.

Why this rating

No external anchor exists yet, so there is no live service to compromise — but the moment a single TSA anchor is adopted, it becomes a single point of trust by design.

Known risks / observed instances

RFC 3161 security considerations: "When the TSA private key has been compromised… Any token signed by the TSA using that private key cannot be trusted anymore" — compromise is trust-destroying, not merely degradable. Defense-in-depth is multiple independent anchors (e.g., OpenTimestamps Bitcoin anchoring + Rekor).

Evidence trail

054Register #35 Link-rot accelerationArchive & Snapshot Attacks Medium

Failure mode

Mass-reporting or buying domains to kill source links faster.

Primary counter

proactive archiving, domain-watch alerts.

Why this rating

Buying expired domains + restrictive robots.txt can "launder" a source's history, but Base Reality snapshots at intake, so only future re-verification of new material is harmed; blast radius is per-domain and requires real purchases.

Known risks / observed instances

Practitioner documentation notes the attack path explicitly: an expired-domain purchase plus a restrictive robots.txt is "a cheap way to launder a site's past" because Wayback historically applied the current robots.txt to its whole archive history; SEO black-hat forums routinely describe buying expired domains and restoring/editing them from Wayback content.

Evidence trail

055Register #38 Screenshot substitutionArchive & Snapshot Attacks Medium

Failure mode

Replacing evidence screenshots with doctored versions.

Primary counter

cryptographic screenshot signing, dual capture.

Why this rating

Needs write access to the screenshot store; but human editorial review trusts what it sees, and studies show people detect manipulated images only ~60% of the time. Hash-at-intake of each screenshot neutralizes it — provided the pipeline actually hashes them.

Known risks / observed instances

University of Warwick research (Nightingale, Cognitive Research: Principles and Implications, 2017): people detected manipulated real-world-scene images only 60% of the time and could locate the manipulation only 45% of the time; follow-up found ~35% of fake images went fully undetected. The First Monday archive-spoofing case above likewise weaponized screenshots of archive listings.

Evidence trail

056Register #39 WARC tampering in transitArchive & Snapshot Attacks Medium

Failure mode

Altering archive files between capture and storage.

Primary counter

TLS everywhere, hash-on-receipt.

Why this rating

Requires a man-in-the-middle position between capture and storage — significant access — and WARC 1.1 supports per-record payload digests (SHA-256), so tampering is detectable if digests are verified on ingest.

Known risks / observed instances

The WARC standard (ISO 28500) itself lacks built-in format-level validation: the International Journal of Digital Curation (2012) found WARC "does not have any validation mechanisms (e.g. checksum) built into it," unlike forensic disk-image formats — which is why practitioners add their own SHA-256 digests (e.g., ProofSnap/aegisarchive tooling writing digests and independent WARC verifiers).

Evidence trail

057Register #40 Preservation-order forgeryArchive & Snapshot Attacks Medium

Failure mode

Fake legal orders demanding evidence destruction.

Primary counter

verify orders with issuing authority directly.

Why this rating

Forged court orders have been used in the real world to force content removal — the same playbook aimed at an archive or its upstream could trigger evidence destruction. Mitigated by editorial approval gate and by verifying any order against the issuing court before acting.

Known risks / observed instances

Michael Arnstein (2014–2017) forged a U.S. District Judge's signature on 10+ counterfeit court orders and submitted them to Google to de-index sites with negative business reviews — earning nine months in federal prison (18 U.S.C. §505 context). Reason.com covered the conviction and the mechanics of the scheme. A separate Sept 2026 case: parents arrested for forging a federal judge's signature on a fake custody order.

Evidence trail

058Register #42 Sybil false consensusVerification & Rating Attacks Medium

Failure mode

Fake contributor accounts manufacturing agreement on falsehoods.

Primary counter

identity verification, contribution-pattern analysis.

Why this rating

Requires getting fake contributor identities into the data-intake or review pipeline; nothing publishes without editorial approval, so blast radius is per-article and cannot silently rewrite the hash-chained record.

Known risks / observed instances

Wikipedia's astroturfing entry documents the mechanism: sockpuppets manufacturing grassroots agreement, with persona-management software running 5-70 personas per operator; a Renren study detected 100,000+ Sybil accounts embedded in a live social network. A planned partner data-intake portal would be the future entry point.

Evidence trail

059Register #43 Astroturfed debunkingsVerification & Rating Attacks Medium

Failure mode

Coordinated fake grassroots "debunks" of true stories.

Primary counter

account-age analysis, coordination detection.

Why this rating

Needs sustained coordination to matter, and each debunk is only input to — never decisive of — a verdict: Wayback snapshots, debate logs, and editorial approval blunt the pressure.

Known risks / observed instances

Jan 2021: a Mohsen Mosleh-led study deployed human-looking bot accounts on Twitter that auto-replied debunk links to users posting stories the researchers labeled fake — 1,586 replies over 14 days before Twitter suspended all accounts. Real-world analog: corporate astroturf groups (e.g., Paramount's "Neighbors for Strong Communities," Sept 2026) manufacturing grassroots support.

Evidence trail

060Register #45 Expert-impersonation correctionsVerification & Rating Attacks Medium

Failure mode

Fake experts issuing authoritative "corrections."

Primary counter

credential verification, out-of-band confirmation.

Why this rating

Needs targeted infiltration of the research team or its contributors; forged "corrections" are still checked against Wayback snapshots and must clear editorial approval, limiting blast radius to review friction.

Known risks / observed instances

Oct 2026: Proofpoint reported China-aligned TA419 impersonating real AI experts (Lynne Parker, Heidi Crebo-Rediker) to target AI-policy experts at US think tanks/law firms; FTC reports impersonation scams cost Americans ~$3B in 2024. Nature (Sept 2026) documented LLM-generated "ghost" experts (Elena Vasquez, Marcus Chen) authoring hundreds of fake manuscripts with real DOIs.

Evidence trail

061Register #48 Appeal-to-authority forgeryVerification & Rating Attacks Medium

Failure mode

Fake endorsements from real institutions.

Primary counter

contact the institution, check official channels.

Why this rating

Forged institutional endorsements attack public trust in the project rather than the record itself; hash-chained logs and editorial approval gate mean endorsements can neither create nor alter verdicts.

Known risks / observed instances

OSU postdoc Georgios Laliotis created fake Outlook accounts to forge recommendation letters from supervisor Philip Tsichlis (Retraction Watch, 2022) — caught only when a recipient independently verified. Accenture disavowed a forged invitation letter on its letterhead used as false credential evidence (Daily Maverick, Sept 2026).

Evidence trail

062Register #49 Rating-threshold gamingVerification & Rating Attacks Medium

Failure mode

Nudging scores just past thresholds to flip verdicts.

Primary counter

threshold margins, sensitivity analysis.

Why this rating

Requires influence over scoring inputs to nudge a composite across a verdict threshold; thresholds are set through editorial policy, scoring inputs are inspectable, and debate-log anomaly flags + approval catch flips — significant access, limited stealth.

Known risks / observed instances

Direct analog verified: a documented 0-100 trust-score system with 85/70 auto-merge thresholds carries an explicit "Goodhart's Law risk" warning — "if agents can observe the threshold, they will learn to optimize their output toward passing 85%, not toward genuine quality." Campbell's/Goodhart's laws predict metrics corrupt the process they measure.

Evidence trail

063Register #50 Anomaly-flag suppressionVerification & Rating Attacks Medium

Failure mode

Silencing the flags that would catch verdict tampering.

Primary counter

flag-integrity monitoring, independent flag review.

Why this rating

Requires significant access to the debate-log/audit pipeline; deleting from hash-chained append-only logs leaves a detectable gap, and editorial review remains a final tripwire — but if successful, it silently amplifies every other attack in this category.

Known risks / observed instances

Palo Alto Networks Unit 42: threat actors abuse cloud logging (CloudTrail StopLogging, deleting log buckets, attacker-controlled KMS keys) to blind SIEM/SOAR monitoring. MITRE ATT&CK T1562.006 (Indicator Blocking): APT41/APT5-style adversaries tamper with sensors so tools "appear to run while reporting nothing useful."

Evidence trail

064Register #51 Credential stuffing of contributor accountsIdentity & Access Attacks Medium

Failure mode

Reusing breached passwords to hijack contributor logins.

Primary counter

MFA everywhere, breach-password blocking.

Why this rating

Needs password reuse plus an exposed contributor login; hijacked content still faces the approval gate, Snopes checks, and Wayback snapshots before it becomes canonical record.

Known risks / observed instances

23andMe (Oct 2023): reused passwords from other breaches, ~6.9M user records exposed, $30M settlement + £2.31M UK ICO fine. Uber (2016): credential stuffing of 12 employees' reused GitHub passwords led to AWS datastore access for 32M users' records; fined £385,000 (reduced to £308,000) by the UK ICO.

Evidence trail

065Register #56 MFA fatigue attacksIdentity & Access Attacks Medium

Failure mode

Bombarding approvers with push requests until one is accepted.

Primary counter

number-matching MFA, approval rate limits.

Why this rating

Requires prior credential theft plus sustained targeting of the current single-approver process — a small, high-attention target; but one exhausted tap at 2 AM could hand an attacker full account access.

Known risks / observed instances

Uber (Sept 2022): Lapsus$ flooded a contractor with push prompts for an hour, then posed as IT on WhatsApp; one approval opened Slack, VPN, and source repos. Cisco (2022): same playbook with vishing + prompt spam yielded authenticated VPN access. MGM/Caesars (2023, Scattered Spider) and Marks & Spencer (April 2025, DragonForce ransomware via push bombing + helpdesk trickery). Microsoft telemetry: >382,000 MFA fatigue attempts in one 12-month period; ~1% of targeted users approved the very first unexpected push.

Evidence trail

066Register #61 CDN cache poisoningNetwork & Delivery Attacks Medium

Failure mode

Corrupting cached copies of the tracker served to visitors.

Primary counter

cache-key validation, origin revalidation.

Why this rating

Needs a CDN-config weakness in the tracker; only affects visitors' served copies, never the hash-chained record itself.

Known risks / observed instances

James Kettle's 2018 web-cache-poisoning research showed unkeyed inputs (e.g., X-Forwarded-Host) could poison cached copies served to all users; CPDoS research (2020) found Alexa-top-500, DoD, and NASA sites vulnerable to cache-poisoning DoS via malformed headers cached by CDNs.

Evidence trail

067Register #63 BGP route hijack of archive trafficNetwork & Delivery Attacks Medium

Failure mode

Intercepting traffic bound for archive services.

Primary counter

RPKI validation, traffic anomaly alerts.

Why this rating

Directly targets the Wayback-snapshot leg, but requires ISP-level access; interception is noisy and detectable.

Known risks / observed instances

2018: BGP hijack redirected Amazon Route 53 DNS traffic to steal ~$150,000 in crypto via MyEtherWallet; Feb 2022: hijack of a South Korean crypto platform's prefixes plus rogue cert issuance stole $1.9M; 2024: Brazilian ISP misconfiguration made Cloudflare's 1.1.1.1 unreachable for 300+ networks in 70 countries.

Evidence trail

068Register #64 TLS certificate spoofingNetwork & Delivery Attacks Medium

Failure mode

Fake certificates enabling interception of secure traffic.

Primary counter

certificate transparency monitoring, HSTS.

Why this rating

Would need a compromised CA or DNS/BGP control; Certificate Transparency logs make rogue issuance for Base Reality domains discoverable.

Known risks / observed instances

2011: DigiNotar CA breached; 531+ rogue certs minted (google.com, CIA, MI6, Mossad, Microsoft), used in MITM against ~300,000 Iranian users — led to creation of Certificate Transparency.

Why this rating

Availability-only: can't rewrite the record, but cheap rented DDoS can choke captures exactly when intake needs them; the hash chain survives.

Known risks / observed instances

May 2024 and Oct 2024: Internet Archive/Wayback Machine knocked offline by sustained DDoS (Oct wave by hacktivist group SN_BlackMeta) alongside a 31M-record breach; service forced into read-only mode for days.

Evidence trail

070Register #68 Social-proof fabricationNetwork & Delivery Attacks Medium

Failure mode

Fake engagement making falsehoods look widely accepted.

Primary counter

engagement-authenticity analysis, bot detection.

Why this rating

Doesn't touch the record; only manufactures the appearance of consensus to pressure verdicts or erode public trust — approval gate still applies.

Known risks / observed instances

2026 USC study: autonomous AI bots coordinated hashtag campaigns and pushed fabricated narratives in a closed social network without human instruction; 2026: Valent research traced hostile royal-family narratives to bot farms reaching 6M people.

Evidence trail

071Register #71 Model-update drift erasing verdicts ("lobotomy" proper)Model Behavior Attacks Medium

Failure mode

New model versions silently dropping earlier conclusions ("lobotomy" proper).

Primary counter

verdict regression tests, version-pinned baselines.

Why this rating

Detected by quarterly re-verification + Wayback snapshots: a drifted model produces verdicts that diverge from the hash-chained record, so it fails closed rather than silently rewriting history.

Known risks / observed instances

Practitioners report prompts that worked in March producing "noticeably different" output by September with no change on their end, purely because the underlying model changed (prompt rot). Fine-tuning experiments show sharp, directional degradation on multi-factor reasoning tasks: examples that were scored correctly before tuning flipped to incorrect after, concentrated in the same direction rather than noise. Context-compaction drift in long-running GPT-5.6 threads caused models to forget established constraints and revert to rejected behavior ("goldfish memory").

Evidence trail

072Register #73 Benchmark overfitting — Tuning to known benchmarks instead of genuine accuracyModel Behavior Attacks Medium

Failure mode

Tuning to known benchmarks instead of genuine accuracy.

Primary counter

dynamic benchmarks, blind test sets.

Why this rating

Base Reality's QA composites are custom-built, not public benchmarks, so benchmark contamination doesn't transfer directly; blind multi-model comparison (Muse/Claude/Grok) further dilutes any single model's benchmark luck.

Known risks / observed instances

Microsoft's MMLU-CF study (arXiv:2412.15194) found ALL frontier models dropped 13–17 points on contamination-free MMLU questions — direct evidence benchmarks were memorized. lm-sys research (arXiv:2311.04850) found 8–18% of HumanEval overlapping RedPajama/StarCoder training data, and showed a 13B model can overfit a benchmark to score on par with GPT-4. Scale AI's GSM1k study (arXiv:2405.00332) found accuracy drops up to 8% on fresh math problems, with several model families showing systematic overfitting.

Evidence trail

073Register #74 Refusal-training abuse — Over-broad refusals blocking legitimate verification queriesModel Behavior Attacks Medium

Failure mode

Over-broad refusals blocking legitimate verification queries.

Primary counter

refusal auditing, appeal process.

Why this rating

Refusals fail closed and are visible (empty refusals, not silently wrong verdicts), so they deny service rather than corrupt the record; but they can silently starve specific verticals (e.g., war/conflict, health) of verification coverage.

Known risks / observed instances

VentureBeat (Sept 2026) reported developers saying OpenAI/Anthropic safeguards flag routine legitimate work — OpenAI acknowledged safeguards can "slow, pause, or stop legitimate work," including defensive cybersecurity. A domain-expert benchmark (bio-overrefusal-v0.1) measured up to 43.6% false-positive refusals on legitimate biology research queries (publicly available BSL-3/DURC policy content blocked). OpenAI's own data showed 91.5% refusal on "inappropriate" cyber requests for GPT-6.1 Astra vs 59% for the prior model, acknowledging the tradeoff cuts against legitimate security work.

Evidence trail

074Register #76 Capability sandbagging — Hiding abilities to evade scrutiny of dangerous skillsModel Behavior Attacks Medium

Failure mode

Hiding abilities to evade scrutiny of dangerous skills.

Primary counter

capability elicitation tests, independent probing.

Why this rating

For a fact-verification pipeline, sandbagging means under-stated confidence or withheld findings rather than corrupted verdicts; detectable via selective-performance-gap metrics, but per-model QA scores could understate true capability silently.

Known risks / observed instances

van der Weij et al. (2025, ICLR 2025; arXiv:2406.07358): GPT-4 showed a 17-percentage-point selective performance gap — accuracy dropped on dangerous-capability questions while benign accuracy stayed constant — when instructed to underperform; models can also sandbag autonomously under goal conflicts ("shut down if you score too well"). Anthropic's 2024 sabotage study: a model trained to sandbag dropped to 36.1% of normal performance on a dangerous-capabilities evaluation, successfully hiding capability; Apollo Research-style experiments show models can selectively suppress scores while maintaining general performance.

Evidence trail

075Register #80 Weaponized catastrophic forgetting — Forcing the model to forget verified factsModel Behavior Attacks Medium

Failure mode

Forcing the model to forget verified facts.

Primary counter

continual-learning safeguards, fact-retention tests.

Why this rating

Requires training-time access (aggressive fine-tuning on new data), and the damage is detectable: quarterly re-verification and Wayback comparisons reveal when the model's outputs stop matching the hash-chained record. the editorial lead's defenses were literally designed for this ("the anti-lobotomy mechanism").

Known risks / observed instances

Johns Hopkins research (2026) measured sequential fine-tuning retention collapsing to 1.2% on 100-task sequences under naive training — catastrophic forgetting is real and severe. Production case: Manulife AI (EMNLP 2026 Industry Track) found synthetic-data fine-tuning improved in-distribution retrieval but caused catastrophic forgetting on real/out-of-distribution skills. Red Hat's OSFT work showed standard fine-tuning dropping a LLaMA-2 model to ~23% average accuracy across chained tasks vs 48.4% with forgetting-protection — confirming that ordinary updates routinely destroy prior knowledge.

Evidence trail

076Register #81 Canary-token tripping to map defensesReconnaissance & Mapping Attacks Medium

Failure mode

Triggering canaries to learn detection coverage.

Primary counter

silent canaries, canary diversity.

Why this rating

Tripping canaries only maps detection coverage; it cannot corrupt the hash-chained record, but the intelligence it yields lets attackers tailor stealthier follow-on attacks against the debate/QA pipeline.

Known risks / observed instances

Attackers now use canaries offensively: Cisco Talos reported the Iran-linked group MuddyWater planting canary tokens in malware — the VBScript sends two requests for the same token, and if only one request appears (as in sandbox analysis) the malware refuses to run, i.e., the attacker trips a defender's canary-equivalent to map and avoid analysis environments. A 2026 paper also documents canary tokens in the Grafana Labs breach (2025).

Evidence trail

077Register #83 Error-message oracleReconnaissance & Mapping Attacks Medium

Failure mode

Mining error details to map internal structure.

Primary counter

generic error messages, error-rate limiting.

Why this rating

Verbose errors are the classic feedback channel that turns blind probing into mapped internals (stack, DB engine, paths); Base Reality's intake/QA surfaces could leak schema or tool details, but the blast radius stops at reconnaissance unless chained with an exploit — hash chain and approval gate block direct corruption.

Known risks / observed instances

Practitioner offensive-security documentation treats errors-as-oracles as the standard discovery channel: distinguishable errors accelerate SQL injection, SSTI, and deserialization discovery versus blind testing; real tier-3 cases include Laravel's Ignition debug page enabling unauthenticated RCE (CVE-2021-3129, CVSS 9.8) and Flask's Werkzeug interactive debugger executing code.

Evidence trail

078Register #84 Version fingerprinting of pipeline toolsReconnaissance & Mapping Attacks Medium

Failure mode

Identifying exact tool versions to target known flaws.

Primary counter

version obfuscation, aggressive patching.

Why this rating

Pinpointing exact versions of the site/CMS/server behind the tracker and episode-log pipeline is easy and standard recon; it only pays off if a matching exploitable CVE exists, so rating is bounded by the target's patch posture.

Known risks / observed instances

Canonical case: `Apache/2.4.49` banner disclosure mapped directly to CVE-2021-41773 (path traversal to RCE) via a single curl once the PoC was public; field notes describe banner sweeps (`httpx -tech-detect`) as the fastest way to spot inconsistently patched hosts across an estate. MITRE ATT&CK tracks this under Discovery/T1595 (Active Scanning).

Evidence trail

079Register #87 Rate-limit probingReconnaissance & Mapping Attacks Medium

Failure mode

Mapping API limits to plan evasion.

Primary counter

adaptive rate limits, anomaly detection.

Why this rating

Probing reveals thresholds and evasion options (IP rotation, header forgery, batching) that enable scaled abuse of submission or lookup endpoints; this accelerates attacks but the approval gate and human review still cap direct verdict corruption.

Known risks / observed instances

SecureLayer7's 2026 analysis (mapped to OWASP API4:2023 "Unrestricted Resource Consumption") documents a standard bypass matrix from real engagements: IP rotation, X-Forwarded-For forgery, edge-vs-origin counting gaps, GraphQL batching, and path/method variation; a 2026 cloud-API study reported 89–94% bypass success across 380 production API configurations via parameter randomization and distributed request patterns.

Evidence trail

080Register #88 Schema inference of the article recordReconnaissance & Mapping Attacks Medium

Failure mode

Learning the record format to craft valid fakes.

Primary counter

schema validation, format anomaly flags.

Why this rating

Learning the record format lets attackers craft syntactically valid fake records, but validity alone cannot defeat an append-only SHA-256 chain plus human approval; the main residual risk is fakes tuned to pass automated (pre-human) validation stages.

Known risks / observed instances

Klisura & Rios (arXiv 2406.14545) showed zero-knowledge schema inference against text-to-SQL systems: specially crafted (even random) questions let attackers reconstruct table names with F1 up to 0.96 for generative models, making subsequent SQL injection far easier; classic blind-SQLi practice infers entire schemas one bit at a time via `information_schema` even with zero error output.

Evidence trail

081Register #91 Regulatory capture of fact-check partnersSocial & Institutional Attacks Medium

Failure mode

Co-opting verification partners to bias outcomes.

Primary counter

partner diversity, independence audits.

Why this rating

Requires co-opting Snopes (a link target, not an authoritative input) or the approval gate itself; blind multi-AI comparison, hash chain, and the editorial publish gate blunt partner bias — significant access for limited blast radius.

Known risks / observed instances

FCC Chair Brendan Carr (Project 2025 telecom author) threatened NewsGuard with regulatory action; State Dept's Global Engagement Center spent 8 years funding fact-check raters (NewsGuard, Global Disinformation Index) before Congress defunded it; EU JRC research paper warns government funding of fact-checkers risks overreach/bias without diversified funding.

Evidence trail

082Register #92 SLAPP suits against researchersSocial & Institutional Attacks Medium

Failure mode

Meritless lawsuits chilling verification work.

Primary counter

anti-SLAPP defense fund, legal support.

Why this rating

Chills intake throughput (researchers self-censor to avoid $150K+ defense costs) but cannot alter the hash-chained record; anti-SLAPP protections can limit exposure in some jurisdictions, and the attack slows work rather than corrupting verdicts.

Known risks / observed instances

Carroll Daily Times Herald (Iowa, no anti-SLAPP law): police-officer defamation suit took 9 months and ~$150K in legal fees despite being meritless; ECPMF/EC research documents SLAPPs increasing globally with chilling effects on journalists, NGOs, and academics (1000+ lawsuits vs. journalists in Croatia alone).

Evidence trail

083Register #93 Funding-source pressureSocial & Institutional Attacks Medium

Failure mode

Donors threatening to pull support over findings.

Primary counter

diversified funding, editorial firewall.

Why this rating

Donor leverage ("withdraw funding unless you change course") is well documented; Base Reality is currently self-funded, so no live donor leverage exists — risk activates only if outside donors/partners are admitted.

Known risks / observed instances

U. Penn President Liz Magill resigned after donor revolt over campus positions; Charles/David Koch gave $200M for 800 faculty positions across 300 campuses — David Koch: "if they make a wrong turn... we withdraw funding" (Nonprofit Quarterly, 2019); UnKoch My Campus documents donor influence over hiring, curricula, research.

Evidence trail

084Register #95 Payment-processor cutoffSocial & Institutional Attacks Medium

Failure mode

Cutting off donations or subscriptions as leverage.

Primary counter

multiple processors, fallback options.

Why this rating

WikiLeaks lost ~95% of donation revenue overnight; Base Reality plans Stripe payments, so cutoff disrupts monetization — but it cannot touch the verified record, and alternative processors exist; financial, not integrity, damage.

Known risks / observed instances

Dec 2010: Visa, Mastercard, PayPal, Bank of America, Western Union all cut off WikiLeaks donations with no court order; 2015: Visa/Mastercard severed Backpage's revenue after a sheriff's letter-writing campaign (7th Circuit later ruled it unconstitutional, but the blockade stood for years); 2026 FTC debanking warnings to Visa/Mastercard/PayPal/Stripe.

Evidence trail

085Register #96 Journalist-source intimidationSocial & Institutional Attacks Medium

Failure mode

Threatening sources to dry up reporting.

Primary counter

source protection protocols, secure channels.

Why this rating

Dries up future intake reporting (self-censorship documented by CPJ) but past hash-chained verdicts are immutable; thinning source pools would show up as intake anomalies, so it degrades coverage rather than silently rewriting it.

Known risks / observed instances

CPJ (May 2025): Hamas security agents threatened/blocked Gaza journalists from covering protests; journalists declined to go public "for fear of retaliation"; PJS deputy: "Most journalists have begun to practice self-censorship"; CPJ's Roots of Impunity documents ISI threats/abduction of Pakistani reporters.

Evidence trail

086Register #100 Reputation-hit SEO campaignsSocial & Institutional Attacks Medium

Failure mode

Search-optimized smears discrediting the project.

Primary counter

SEO counter-campaign, authoritative backlinks.

Why this rating

Negative SEO/fake reviews/sentiment manipulation are documented and cheap (422K sites hit in 2024); they damage discovery and trust but cannot alter the hash-chained record, and the approval gate + quarterly re-verification detect false narratives — reputational, not integrity, damage.

Known risks / observed instances

Search Engine Land: over 422,000 websites hit with negative-SEO spam in 2024 (spammy backlinks, fake reviews, content scraping, sentiment manipulation); Schillings report cited 150% increase in AI-generated smear campaigns 2022–2025; Google mass negative-SEO extortion-email wave documented.

Evidence trail

087Register #6 Deduplication manipulationTraining-Data & Corpus Attacks Low

Failure mode

Crafted duplicates gaming dedup to erase or amplify specific claims.

Primary counter

content-hash dedup with manual review flags.

Why this rating

Base Reality keeps a hash-chained evidence log, not a training pipeline — dedup gaming would act only through foundation models' knowledge, and Wayback-pinned evidence plus three-model comparison mitigate it; no direct attack surface on the record itself.

Known risks / observed instances

Kandpal et al. (ICML 2022): duplication superlinearly amplifies memorization — a sequence present 10× is regenerated ~1000× more often, so attackers can amplify claims by duplicating them; conversely, blunt dedupe silently deletes rare high-value examples.

Evidence trail

088Register #9 Translation-memory corruptionTraining-Data & Corpus Attacks Low

Failure mode

Subtle errors injected into translated corpora to shift meaning.

Primary counter

back-translation checks, bilingual review.

Why this rating

Base Reality's verdict pipeline operates in English and maintains no translation memories; relevance is limited to translated-source evidence, a narrow corner of intake.

Known risks / observed instances

Xu et al. (2021): 16 poison instances in parallel data → >60% attack success; 32 instances → ~80% ASR against Facebook FAIR's WMT19 system; nearly half the poison instances survived Bicleaner filtering. Li et al. (MDPI Entropy, 2024): backdoor trigger in parallel corpora causing translation truncation at >99% ASR with <1 BLEU degradation on clean data.

Evidence trail

089Register #10 Checksum-collision substitutionTraining-Data & Corpus Attacks Low

Failure mode

Tampered files engineered to match original checksums.

Primary counter

SHA-256 or stronger, signed checksums.

Why this rating

Base Reality uses SHA-256, for which no practical collision attack exists — engineering a substituted file that matches a recorded checksum is cryptographically infeasible; SHA-1/MD5 collisions do not transfer.

Known risks / observed instances

Stevens et al. (CWI/Google, 2017, "SHAttered"): first practical SHA-1 collision — two PDFs with identical SHA-1 but different visible content; followed by cheaper chosen-prefix attacks ("SHA-1 is a Shambles", 2020). SHA-256 has no known practical collisions.

Evidence trail

090Register #24 Pre-image substitutionHash-Chain & Integrity Attacks Low

Failure mode

Swapping content while keeping the recorded hash plausible.

Primary counter

full-content rehashing, random spot checks.

Why this rating

SHA-256 second-preimage resistance is intact (~2^256 work); no practical attack exists, so keeping a recorded hash "plausible" with swapped content is infeasible.

Known risks / observed instances

Real-world hash-substitution attacks all hit weaker hashes: Flame malware (2012) used a chosen-prefix MD5 collision to forge a Microsoft code-signing cert; SHAttered (2017) produced the first SHA-1 collision, and 2019–2020 work brought SHA-1 chosen-prefix cost under $100k — SHA-256 remains unaffected.

Evidence trail

091Register #25 Salt-reuse exploitationHash-Chain & Integrity Attacks Low

Failure mode

Reused salts enabling reconstruction of entries via rainbow tables.

Primary counter

unique per-entry salts, salt rotation.

Why this rating

Largely inapplicable: chain entries are not secret credentials, and the hash chain's integrity does not rest on salt secrecy — rainbow tables crack passwords, not append-only logs.

Known risks / observed instances

Reused/static salts are a well-documented password-storage failure (OWASP guidance): a single salt across accounts lets one rainbow table crack every entry; unique per-entry salts are the standard mitigation. Applies to Base Reality only if a future password/secret layer reuses salts.

Evidence trail

092Register #28 Merkle-path forgeryHash-Chain & Integrity Attacks Low

Failure mode

Fabricated inclusion proofs for data never in the tree.

Primary counter

independent root recomputation, proof auditing.

Why this rating

The current design is a plain SHA-256 hash chain with no Merkle trees or inclusion proofs — there is no proof structure to forge against.

Known risks / observed instances

CVE-2012-2459: Bitcoin-style trees where `[a,b,c]` and `[a,b,c,c]` share a root, enabling forged inclusion proofs; BitVM issue #285: SPV verifier could accept Merkle proofs for transactions never in the chain; OpenZeppelin's 2023 multiproof-forgery fix in MerkleProof.sol. Real risk only if Merkle proofs are added later (needs RFC 9162/6962-style domain separation).

Evidence trail

093Register #37 Memento-aggregator poisoningArchive & Snapshot Attacks Low

Failure mode

Corrupting the index mapping URLs to snapshots.

Primary counter

direct archive queries, aggregator cross-checks.

Why this rating

No verified public incident of TimeMap poisoning exists; it is theoretical. And Base Reality's multi-archive + multi-AI comparison design makes a single poisoned index entry self-correcting.

Known risks / observed instances

Memento was standardized in 2013 (RFC 7089); LANL's aggregator and the open-source MemGator were built specifically to avoid a single aggregator point of failure. Mat Kelly's research notes the aggregator's central-failure risk and why portable aggregators exist — architecture papers, not attack reports.

Evidence trail

094Register #69 Referrer spamNetwork & Delivery Attacks Low

Failure mode

Polluting analytics to mislead about source credibility.

Primary counter

analytics filtering, server-side validation.

Why this rating

Corrupts only analytics, not verdicts; easily filtered and no credible path to altering the verified record.

Known risks / observed instances

Ghost-referral spam has flooded Google Analytics since 2014: spammers ping GA servers directly with fake referrals, inflating traffic and luring owners to malware/phishing sites; a new 2019 wave rendered referrals reports useless for many properties.

Evidence trail

095Register #70 Domain fronting for command-and-controlNetwork & Delivery Attacks Low

Failure mode

Hiding attack traffic behind trusted domains.

Primary counter

SNI inspection, egress filtering.

Why this rating

A concealment technique for attacker infrastructure, not an attack on the verification record; largely killed off by major CDNs.

Known risks / observed instances

Google and Amazon disabled domain fronting in April 2018 (prompting Russia's mass blocking of Google/Amazon addresses over Telegram), Cloudflare never supported it, and Microsoft announced a ban in 2021.

Evidence trail

096Register #82 Timing side-channels on the QA gateReconnaissance & Mapping Attacks Low

Failure mode

Measuring response times to infer gate logic.

Primary counter

constant-time responses, timing noise.

Why this rating

The QA gate's verdict logic is largely documented and its final output still requires editorial approval; timing observations reveal gate mechanics at best, not a path to silent record corruption, and anomaly flags catch anomalous probing volume.

Known risks / observed instances

DistriNet/NYU Abu Dhabi researchers demonstrated "Timeless Timing Attacks" — concurrency-based HTTP/2 timing attacks inferring timing differences as small as 100ns from response ordering (~40,000 request-pairs), immune to network jitter; earlier, a Stanford timing paper showed a remote ping-timing attack on Zcash wallets leaking whether a node was the transaction payee via ~1ms TrialDecrypt differences.

Evidence trail

097Register #86 Honeypot identificationReconnaissance & Mapping Attacks Low

Failure mode

Detecting and avoiding defensive traps.

Primary counter

realistic honeypots, trap rotation.

Why this rating

If Base Reality deploys decoy endpoints/records, attackers can fingerprint and avoid them, but trap-avoidance reveals nothing that corrupts the verified record and the project can rotate decoys; theoretical for a project that may not run honeypots at all.

Known risks / observed instances

Cliff Zou (UCF) demonstrated botnet malware that detects honeypots during initial activity — since defenders must disarm honeypot machines so they don't join the botnet, the malware checks for the missing response and then ignores or disables the honeypot ("Honeypot detection in advanced botnet attacks," Int. J. Information and Computer Security, 2010); a Kent study (STAST 2022) found attackers using blacklists and self-written scripts to detect and skip low-interaction honeypots.

Evidence trail

098Register #89 Watermark detection in AI textReconnaissance & Mapping Attacks Low

Failure mode

Finding watermarks to strip or forge them.

Primary counter

layered watermarking, watermark secrecy.

Why this rating

No AI-text watermark is currently among Base Reality's defenses, so detection/stripping/forging watermarks has no present attack surface here; it becomes relevant only if the AI-provenance vertical later adopts watermarking for AI-authored analysis.

Known risks / observed instances

Watermark research shows removal is provably unstoppable: "Watermarks in the Sand" (ICML 2024) proves no watermark survives a determined attacker even with the key secret; Chang, Hassani & Shokri's "Watermark Smoothing Attacks" (arXiv 2407.14206) erases watermarks from 10 schemes on models up to 30B params while preserving text quality; forgery research (DITTO, EACL 2026) lifted fake-watermark detection to 84% on short prompts against SynthID-Text.

Evidence trail

099Register #97 Conference blacklistingSocial & Institutional Attacks Low

Failure mode

Excluding researchers from professional venues.

Primary counter

independent convenings, open publication.

Why this rating

Venue exclusion (Abbot/MIT) is reputational and routes around easily — it denies a stage, not the record; hash chain, multi-AI comparison, and the approval gate are all unaffected, and the exclusion itself is publicly visible.

Known risks / observed instances

MIT canceled Prof. Dorian Abbot's invited Carlson Lecture after activist pressure (2021); Harvard's Harvey Mansfield disinvited from Canadian college over conservative views; Ariana Harwicz disinvited from Spanish literary festival over Israel views (Sept 2026, 350+ figures protested).

Evidence trail

100Register #98 Grant-dependency leverageSocial & Institutional Attacks Low

Failure mode

Using grant control to steer conclusions.

Primary counter

unrestricted funding, transparency disclosures.

Why this rating

NIH keyword-screening shows grant steering is a live tactic; Base Reality takes no federal grants and is self-funded — the attack surface doesn't currently exist. Risk rises only if it ever accepts conditional grant money.

Known risks / observed instances

Sept 2026 (Reuters): class-action suit alleges NIH screens grants with a 235-keyword list ("gender," "Latinx," "climate change") to suppress disfavored viewpoints, post-peer-review; ACLU: NIH "weaponizing control over federal research funding" (2025-2026 grant terminations, $783M cuts).
