๐ŸŽฏ Purpose & Scope

Establish a comprehensive threat model for the EU Parliament Monitor multi-language transparency platform (European Parliament data, automated news generation, AWS S3 + CloudFront deployment). This systematic threat analysis integrates multiple threat modeling frameworks to ensure proactive security through structured analysis.

๐ŸŒŸ Transparency Commitment

This threat model demonstrates ๐Ÿ›ก๏ธ cybersecurity consulting expertise through public documentation of advanced threat assessment methodologies, showcasing our ๐Ÿ† competitive advantage via systematic risk management and ๐Ÿค customer trust through transparent security practices.

โ€” Based on Hack23 AB's commitment to security through transparency and excellence

๐Ÿ“š Framework Integration

  • ๐ŸŽญ STRIDE per architecture element: Systematic threat categorization
  • ๐ŸŽ–๏ธ MITRE ATT&CK mapping: Advanced threat intelligence integration
  • ๐Ÿ—๏ธ Asset-centric analysis: Critical resource protection focus
  • ๐ŸŽฏ Scenario-centric modeling: Real-world attack simulation
  • โš–๏ธ Risk-centric assessment: Business impact quantification

๐Ÿ›๏ธ NIST CSF 2.0 GV (Govern) Alignment: This threat model directly supports the GV.OC (Organizational Context) function by documenting how the EU Parliament Monitor's democratic transparency mission shapes risk tolerance, asset priorities, and threat actor motivations. The platform's public-interest mandate โ€” providing open access to European Parliament activities โ€” defines its unique threat landscape: integrity of parliamentary data is the primary security concern, not confidentiality. This GV.OC alignment drives the prioritization of Impact and Initial Access tactics in ATT&CK coverage, and informs the Low risk appetite for content manipulation threats across all 14 supported languages.

Coverage Rationale: The EU Parliament Monitor's 2.3% overall coverage reflects focused threat modeling for a static site with EP MCP Server integration. Higher coverage in Initial Access (18.2%), Collection (4.9%), Command & Control (4.3%), and Discovery (4.1%) aligns with primary threat vectors for public-facing platforms with external API dependencies. The 16 techniques mapped include 7 EP MCP Server-specific vectors added in v1.1.

๐Ÿ”Œ EP MCP Server Attack Surface Analysis

The European Parliament MCP Server integration (european-parliament-mcp-server) introduces a specific attack surface that requires dedicated threat analysis. As an ephemeral, localhost-only process invoked during GitHub Actions builds, its exposure window is narrow โ€” but its role in data ingestion makes integrity controls critical.

Description: Adversarial text embedded in MCP-fetched EP debates, plenary transcripts, or MEP-authored documents contains instructions intended to steer downstream LLM generation (bypass safety, rewrite facts, inject URLs, or exfiltrate system prompts) during the gh-aw agentic news pipeline.

Existing Controls:

  • โœ… scripts/utils/validate-analysis-completeness.js scans FALLBACK_TEMPLATE_PATTERNS and AI_MARKER sentinels

Description: The LLM fabricates citations (EP document references, MEP names, voting dates, procedure IDs) that do not exist, producing plausible-looking but false parliamentary references in generated articles.

Existing Controls:

  • โœ… analysis/methodologies/reference-analysis-quality.md word-count gate (โ‰ฅ140, breaking โ‰ฅ190)
  • โœ… Cross-reference validation in src/utils/validate-analysis-completeness.ts (compiled to scripts/utils/validate-analysis-completeness.js)

STRIDE CategoryTampering, Spoofing
MITRE ATT&CKT1584 (Compromise Infrastructure), T1565 (Data Manipulation)
Threat AgentNation-State Actor, Advanced Persistent Threat
LikelihoodLow-Medium (2/5)
ImpactMedium (3/5) โ€” Poisoned data propagates to all 14 languages
Risk ScoreLow-Medium (6/25)
PriorityP2

Description: Compromise of an upstream MCP data source (EP Open Data Portal, World Bank MCP, or IMF REST/SDMX 3.0) causes poisoned MEP records, voting data, or economic indicators to flow into generated articles. Extends T-013 to cover the expanded MCP surface after the Wave-2 OR-gate / Wave-3 strict-gate introduction. Under Wave-3, IMF (dataservices.imf.org) is the primary economic source; a compromise of that single host has higher impact than under Wave-2 because no parallel WB economic citation is required.

Existing Controls:

  • โœ… TLS 1.2+/1.3 on all outbound HTTPS to WB and IMF
  • โœ… Local EP MCP via Docker bridge (trust boundary is Docker bridge, not public internet)
  • โœ… Tool-list drift tests: IMF_MCP_TOOLS and WORLD_BANK_MCP_TOOLS asserted in test/integration/mcp/*
  • โœ… Stage-C completeness review enforces IMF-or-WB economic-context citation per .github/prompts/03-analysis-completeness-gate.md โ€” if one source fails, the other satisfies the editorial policy
  • โœ… {status:"unavailable"} envelope handling degrades gracefully when a source is unreachable
  • โœ… src/utils/html-sanitize.ts sanitizes every MCP string before rendering

Residual Gap: EP MCP client does NOT yet export a canonical EP_MCP_TOOLS list โ†’ no drift test parity with IMF+WB.

Residual Risk: Low-Medium โ€” OR-gate + sanitization limits impact; EP tool-list drift test pending

Risk Treatment: Monitor โ€” Close EP tool-list gap (tracked in CRA gap table)


Threat T-024: Workflow Compile Drift

LikelihoodLow-Medium (2/5)
ImpactMedium (3/5) โ€” Agent bypasses policy encoded in lock-file
Risk ScoreLow-Medium (6/25)
PriorityP2

Description: An agent workflow bypasses its compiled .lock.yml by shipping only the .md source without recompiling, causing the runtime executor to load a stale lock file while maintainers believe the new policy is active.

Existing Controls:

  • โœ… .github/workflows/compile-agentic-workflows.yml validates GH_AW_VERSION=v0.77.3 pin (manual workflow_dispatch โ€” run before merging agentic-workflow changes)
  • โœ… Branch protection prevents merge when compile check fails (when manually triggered)
  • โœ… .lock.yml MUST match {{#runtime-import}} directive in the source .md
  • โœ… Branch protection prevents merge when compile check fails
  • โœ… actions-lock.json tracked in VCS for supply-chain auditability

Residual Risk: Low-Medium โ€” Compile gate is strong but depends on branch-protection enforcement

Risk Treatment: Monitor โ€” Quarterly review of branch-protection settings

Risk ScoreLow (3/25)

Description: A malicious or runaway agent emits a very large patch via safe-outputs that overwhelms human review capacity, hiding malicious edits within bulk legitimate-looking content.

Existing Controls:

  • โœ… max-patch-size: 1024 KB default applied to all gh-aw workflows
  • โœ… Elevated cap of 10240 KB ONLY at the news-translate top level, with documented justification (13 languages ร— ~1 MB each = ~13 MB fan-out)
  • โœ… Safe-outputs schema validation during gh-aw compile
  • โœ… PR review required for merge (no direct push)
  • โœ… GitHub diff UI renders large PRs as "load diff" โ€” reviewers are explicitly prompted

Residual Risk: Low โ€” Caps + PR review are strong; news-translate exception is auditable

Risk Treatment: Accept โ€” Revisit cap values quarterly

MITRE ATT&CKT1078 (Valid Accounts), T1550 (Use Alternate Authentication)
Threat AgentNation-State Actor, Advanced Persistent Threat
LikelihoodLow (1/5)
ImpactHigh (4/5) โ€” Unauthorized npm publish or S3 deploy
Risk ScoreLow-Medium (4/25)
PriorityP2

Description: An overly broad OIDC trust policy on AWS IAM or npm allows a workflow from a different repository, branch, or environment to assume the release role and publish/deploy unauthorized artifacts.

Existing Controls:

  • โœ… OIDC trust policies scoped to branch + repo subject claims (repo:Hack23/euparliamentmonitor:ref:refs/heads/main)
  • โœ… Least-privilege IAM role: S3 PutObject + CloudFront CreateInvalidation only
  • โœ… Least-privilege npm publish scope limited to euparliamentmonitor package
  • โœ… CloudTrail audit of all role assumptions
  • โœ… npm audit logs for every publish

Residual Risk: Low-Medium โ€” Trust-policy drift is the primary residual concern

LikelihoodLow-Medium (2/5)
ImpactHigh (4/5) โ€” 13-language fan-out amplifies bad content
Risk ScoreMedium (8/25) โš ๏ธ P1
PriorityP1

Description: A bad actor uses the 13-language translation fan-out to scale disinformation: contaminated English source โ†’ 13 translations โ†’ published across all locales simultaneously, amplifying reach beyond what single-language manipulation could achieve.

Existing Controls:

  • โœ… news-translate.md ยง"AI-First Pre-Translation Gate" blocks contaminated English sources before fan-out
  • โœ… Reference thresholds (mcp-reliability-audit โ‰ฅ200/385, reference-analysis-quality โ‰ฅ140/190) apply to source English before translation
  • โœ… Human PR review required for merge (catches translation of contaminated source)
  • โœ… news-translate-reconciler.yml sweeps orphaned translations (one locale without matching source)
  • โœ… Pre-translation validator gate documented and enforced in lock file

Residual Risk: Medium โ€” Pre-translation gate is the single point that must hold; if bypassed, all 13 locales are impacted simultaneously

Risk Treatment: Reduce โ€” Harden pre-translation validator with additional sentinels; add per-locale post-translation spot-check

STRIDE CategoryDenial of Service, Tampering
MITRE ATT&CKT1195 (Supply Chain Compromise)
Threat AgentUpstream Project Breakage, Dependency Drift
LikelihoodLow-Medium (2/5)
ImpactLow-Medium (2/5) โ€” Pipeline halts until recompile
Risk ScoreLow-Medium (4/25)
PriorityP3

Description: An upstream breaking change to gh-aw renders the compiled .lock.yml artifacts unexecutable (e.g., schema change, runtime-import signature change, executor removal), halting the 15 agentic workflows (14 article + 1 translate) until recompile + manual bump.

Existing Controls:

  • โœ… GH_AW_VERSION: v0.77.3 pinned in .github/workflows/compile-agentic-workflows.yml
  • โœ… actions-lock.json tracked in VCS
  • โœ… BCP Scenario 11 documents git-revert rollback procedure if bump fails
  • โœ… Drift detection via CI compile job on every PR (catches incompatible bumps early)
  • โœ… 10 .lock.yml files centrally recompiled when pin is changed

Residual Risk: Low-Medium โ€” Pin + rollback procedure limits outage window to <24h RTO

Risk Treatment: Monitor โ€” Watch gh-aw release notes beyond the current v0.77.3 pin and test-bump in fork before production


Threat T-029: Shell Expansion Injection in Agentic Workflows

AttributeValue
Threat IDT-029
STRIDE CategoryTampering, Elevation of Privilege
MITRE ATT&CKT1059.004 (Unix Shell), T1027 (Obfuscated Files/Information), T1546 (Event-Triggered Execution)
Threat AgentPrompt-injection attacker (via EP debate text, IMF metadata, contributor PRs)
LikelihoodMedium (3/5) โ€” AI agents emit bash on every news-generation run
ImpactHigh (4/5) โ€” Arbitrary code execution inside the agentic sandbox
Risk ScoreHigh (12/25)
PriorityP1

Description: A prompt-injection payload embedded in untrusted upstream content (parliamentary debate text, IMF dataset descriptions, contributor PR diff content) coerces an AI agent (Copilot/Claude/Codex) into emitting bash that uses dangerous expansion patterns โ€” ${var@P} (parameter transformation re-eval), ${!var} (indirect expansion), ${A:-${B:-$(cmd)}} (nested default with command substitution), eval "$str", or $(cmd < $(inner)) (nested substitution with redirection). If the gh-aw shell-safety filter does not catch the pattern at parse time, or if a developer commits a hand-written scripts/*.sh that contains such a pattern, an attacker can pivot from injected content to arbitrary command execution inside the GitHub Actions runner โ€” exfiltrating ephemeral tokens, modifying analysis artefacts before PR creation, or persisting via lock-file manipulation.

Existing Controls:

  • โœ… Drift-guard test (test/unit/shell-safety.test.js) โ€” recursively scans every scripts/**.sh file against 9 forbidden-pattern regexes (nested parameter expansion, indirect expansion, parameter transformation @P/@Q/@E/@A/@K/@a, nested command substitution, default-with-command-substitution, redirection inside $(), adjacent ${RANDOM}${RANDOM}, eval). Runs in standard npm run test Vitest suite โ€” gates every PR.
  • โœ… Prompt-level rules โ€” .github/prompts/00-scope-and-ground-rules.md ยง47 (short-form forbidden-pattern list, imported by every news-<type>.md workflow body) + .github/prompts/08-infrastructure.md ยง177-181 (long-form safe-replacement idioms) + .github/prompts/02-analysis-protocol.md ยง10 (mandates delegation to pre-audited scripts/*.sh helpers).
  • โœ… gh-aw shell-safety filter โ€” sandbox-side parser rejects forbidden patterns at workflow execution time (defence-in-depth against patterns that escape the test suite).
  • โœ… AWF Squid egress firewall โ€” even if RCE succeeds, outbound traffic is restricted to the upstream allowlist (no exfiltration to arbitrary hosts).
  • โœ… Ephemeral GITHUB_TOKEN โ€” workflow-scoped, expires at job completion; least-privilege permissions: block per workflow.
  • โœ… Safe-outputs constraints โ€” agent cannot push to protected branches; the only write path is safeoutputs___create_pull_request which lands a PR for review.

Attack Vectors:

  1. Prompt-injection via EP debate content โ€” hostile MEP debate text crafted to coerce the agent into emitting ${VAR@P} or eval $(curl ...).
  2. Contributor PR with crafted scripts/*.sh โ€” committed shell helper containing forbidden patterns; relies on test suite catching at PR-time.
  3. Workflow .md body editing โ€” direct injection into .github/workflows/*.md bash blocks; must pass the gh-aw compile step + lint.

Residual Risk: Low-Medium โ€” Three independent layers (test drift-guard + prompt rules + sandbox parser) + AWF egress containment. The dominant residual risk is a novel expansion pattern not covered by the regex set; mitigated by quarterly review of bash-injection literature and the gh-aw upstream filter rules.

Risk Treatment: Mitigate โ€” Maintain the drift-guard test as part of the test/unit/ baseline; review prompt rules every release; subscribe to the gh-aw security advisory feed for new pattern disclosures.


Threat T-030: MCP Gateway Impersonation & Safe-Outputs Constraint Escape

AttributeValue
Threat IDT-030
STRIDE CategorySpoofing, Elevation of Privilege, Information Disclosure
MITRE ATT&CKT1557 (Adversary-in-the-Middle), T1078 (Valid Accounts), T1199 (Trusted Relationship)
Threat AgentCompromised dependency, malicious MCP server registration, Docker bridge attacker
LikelihoodLow (2/5) โ€” Docker bridge is local-only, but supply-chain risk is real
ImpactHigh (4/5) โ€” Tampered analysis artefacts โ†’ flawed political-intelligence output
Risk ScoreMedium (8/25)
PriorityP2

Description: Two related attack paths share the same trust-boundary surface:

  1. MCP Gateway Impersonation โ€” a malicious process binds to host.docker.internal:8080 (or to a port advertised in /home/runner/.copilot/mcp-config.json) and serves crafted responses to the European Parliament MCP, IMF fetch-proxy, or World Bank MCP endpoints. The agentic workflow consumes the poisoned data and writes plausible-looking but factually false analysis artefacts. Because the agent is gradient-corrected toward Economist-quality prose, the resulting articles would still pass Stage-C completeness gates while encoding the attacker's narrative.
  2. Safe-Outputs Constraint Escape โ€” the safe-outputs subsystem enforces that the only way an agent can mutate the repository is via a constrained create_pull_request call (no direct push, no branch deletion, no protected-ref edits). An attacker who finds a parser bug in the safe-outputs validator, or who tampers with the compiled .lock.yml between compile and execute, could inject extra mutations (e.g. modifying package-lock.json to introduce a typosquat).

Existing Controls:

  • โœ… Local-only MCP transport โ€” EP_MCP_GATEWAY_URL defaults to host.docker.internal:8080. The Docker bridge is not reachable from outside the runner; impersonation requires a co-located malicious container.
  • โœ… Auth-token extraction via scripts/mcp-setup.sh โ€” uses node -e JSON parsing, not shell expansion of untrusted JSON values; eliminates the class of "API key injected via shell metacharacter" attacks.
  • โœ… 180s MCP timeout (MCP_CLIENT_TIMEOUT_MS=180000) โ€” bounds the blast radius of a hung or slow-loris MCP impersonator.
  • โœ… Drift-proofing tool list assertions โ€” test/integration/mcp/imf-mcp.test.js, worldbank-mcp.test.js, and ep-mcp.test.js assert that the tool catalogue exposed by each MCP server matches the canonical exports in src/mcp/*-mcp-client.ts. Any silent tool addition (a likely impersonation indicator) fails CI.
  • โœ… Cross-source triangulation โ€” IMF + EP + World Bank are independent providers. Stage-C validators flag claims supported by only one source; the editorial IMF-primary policy means any economic claim must reconcile across IMF and the article narrative.
  • โœ… Lock-file compilation (compile-agentic-workflows.yml) โ€” compiles .github/workflows/*.md to .lock.yml deterministically; PR diff review catches unexpected changes to the compiled artefact.
  • โœ… Safe-outputs schema validation โ€” the agent's create_pull_request call payload is schema-validated; non-conforming mutations are rejected before reaching the GitHub API.
  • โœ… max-patch-size cap โ€” limits how large a single safe-output PR can be, bounding the impact of a successful escape (T-025 covers the bypass attempt).
  • โœ… OIDC for AWS / npm โ€” no long-lived deployment credentials accessible to a compromised MCP server.

Attack Vectors:

  1. Co-located malicious container binding host.docker.internal:8080 first (race condition with the legitimate MCP gateway). Mitigated by gh-aw startup sequencing + drift-proofing tool list checks.
  2. **Compromised european-parliament-mcp-server npm package (T-002 / T-012 coverage). Pinned to 1.3.12 with provenance verification.
  3. Parser bug in the safe-outputs validator allowing extra fields. Mitigated by gh-aw upstream test coverage + lock-file diff review.
  4. .lock.yml tampering between compile and execute (T-024 coverage).

Residual Risk: Low โ€” Docker-bridge locality + drift-proofing + cross-source triangulation + safe-outputs schema together cap exploitability. Residual risk is dominated by undisclosed parser bugs in the gh-aw safe-outputs validator (out of repository control).

Risk Treatment: Mitigate โ€” Maintain drift-proofing tool list assertions; subscribe to gh-aw security advisories; quarterly review of .lock.yml diff patterns for anomalies.
