feat(llm-security): add /security ide-scan — VS Code / JetBrains extension prescan (v6.3.0)
New standalone scanner (prefix IDE) discovers installed VS Code extensions across forks (Cursor, Windsurf, VSCodium, code-server, Insiders, Remote-SSH) and runs 7 IDE-specific threat checks: blocklist match (CRITICAL), theme-with-code, sideload (unsigned .vsix), dangerous uninstall hook (HIGH), wildcard activation, extension-pack expansion, typosquat (MEDIUM). Per-extension reuse of UNI/ENT/NET/TNT/MEM/SCR scanners with bounded concurrency. Offline-first; --online opt-in. JetBrains discovery stubbed for v1.1. 22 new tests (1296 total, was 1274).

Security scanning, auditing, and threat modeling for agentic AI projects.
|

Built on OWASP LLM Top 10 (2025), OWASP Agentic AI Top 10, and the AI Agent Traps taxonomy (Google DeepMind, 2025). Three layers of protection:
|
||||
|
||||
- **Automated enforcement** — 9 hooks that block dangerous operations in real time (prompt injection, secrets in code, destructive commands, supply chain guardrails, transcript scanning before context compaction)
|
||||
- **Deterministic scanning** — 21 Node.js scanners (10 orchestrated + 11 standalone) for byte-level analysis: Shannon entropy, Unicode codepoints, typosquatting detection, taint flow, DNS resolution, git forensics, AI-BOM, attack simulation. Bash-normalize T1-T6 for obfuscation-resistant denylists
|
||||
- **Advisory analysis** — 18 commands that scan, audit, and model threats with structured reports, letter grades, and actionable remediation
|
||||
- **Deterministic scanning** — 22 Node.js scanners (10 orchestrated + 12 standalone) for byte-level analysis: Shannon entropy, Unicode codepoints, typosquatting detection, taint flow, DNS resolution, git forensics, AI-BOM, attack simulation, IDE extension prescan. Bash-normalize T1-T6 for obfuscation-resistant denylists
|
||||
- **Advisory analysis** — 19 commands that scan, audit, and model threats with structured reports, letter grades, and actionable remediation
|
||||
- **Enterprise governance** — Compliance mapping (EU AI Act, NIST AI RMF, ISO 42001), SARIF 2.1.0 output, structured audit trail, policy-as-code, standalone CLI
|
||||
- **Opus 4.7 aligned** — Agent instructions rewritten for literal instruction-following (system card §6.3.1.1), defense-in-depth posture per §5.2.1, production hardening guide

## [6.3.0] - 2026-04-17
|
||||
|
||||
### Added
|
||||
- **IDE extension prescan** — New `/security ide-scan` command and `scanners/ide-extension-scanner.mjs` (prefix IDE) discover and audit installed VS Code extensions across 6 roots (`~/.vscode/extensions`, `~/.vscode-insiders/extensions`, `~/.cursor/extensions`, `~/.windsurf/extensions`, `~/.vscode-oss/extensions`, `~/.vscode-server/extensions`, plus Linux `code-server`). OS-aware discovery via `scanners/lib/ide-extension-discovery.mjs`. Manifest parsing via `scanners/lib/ide-extension-parser.mjs`. Data loading via `scanners/lib/ide-extension-data.mjs`. JetBrains discovery is a v1.1 stub.
|
||||
- **7 IDE-specific detection categories** — Blocklist match (CRITICAL), theme-with-code (HIGH, Material Theme pattern), sideload `.vsix` (HIGH unsigned / MEDIUM signed), broad activation `*` / `onStartupFinished` (MEDIUM/LOW, suppressed for top-100 exact matches), Levenshtein typosquat ≤2 vs top-100 (HIGH distance-1 / MEDIUM distance-2 against top-50), extension-pack expansion ≥3 (MEDIUM), dangerous `vscode:uninstall` hooks referencing `child_process`/`curl`/`wget`/`rm`/`powershell` (HIGH/LOW)
|
||||
- **Per-extension scanner orchestration** — Each discovered extension runs through UNI, ENT, NET, TNT, MEM, SCR scanners with bounded concurrency (default 4). MEM gets a filtered file list (README.md / CHANGELOG.md / package.json) to catch prompt-injection in marketplace-rendered text
|
||||
- **New knowledge files** — `knowledge/ide-extension-threat-patterns.md` (10 categories with 2024-2026 case studies from Koi Security — GlassWorm, WhiteCobra, TigerJack, Material Theme, VS Code Cryptojacking, MaliciousCorgi), `knowledge/top-vscode-extensions.json` (top ~100 Marketplace IDs + blocklist), `knowledge/top-jetbrains-plugins.json` (stub)
|
||||
- **CLI integration** — `bin/llm-security.mjs` gains `ide-scan` subcommand with passthrough flags
|
||||
- 22 new tests in `tests/scanners/ide-extension-scanner.test.mjs` (fixtures under `tests/fixtures/ide-extensions/`). 1296 tests total (was 1274)

Per-extension orchestration of UNI/ENT/NET/TNT/MEM/SCR scanners with bounded concurrency. OS-aware discovery via `lib/ide-extension-discovery.mjs` (Platform-specific suffix parsing for `darwin-x64`, `linux-arm64`, etc.). Offline-first; `--online` opt-in for future Marketplace/OSV.dev lookups. New knowledge files: `ide-extension-threat-patterns.md` (10 categories, 2024-2026 case studies from Koi Security — GlassWorm, WhiteCobra, TigerJack, Material Theme), `top-vscode-extensions.json` (typosquat seed + blocklist), `top-jetbrains-plugins.json` (stub). 1296 tests (was 1274). |

New `pre-compact-scan.mjs` PreCompact hook — scans transcript tail (500 KB cap, <500 ms) for injection + credentials before context compaction. Modes: `block` / `warn` / `off` via `LLM_SECURITY_PRECOMPACT_MODE`. Agent files reframed for Opus 4.7's more literal instruction-following (Step 0 generaliseringsgrense + parallell Read-hint in skill-scanner + mcp-scanner). New `docs/security-hardening-guide.md` with env-var reference, sandboxing notes, system-card §5.2.1 / §6.3.1.1 mapping. CLAUDE.md Defense Philosophy links to system card. 1274 tests (was 1264). |

Policy `ci` section in `policy.json`. Pipeline templates: GitHub Actions, Azure DevOps, GitLab CI with SARIF upload. CI/CD guide (`docs/ci-cd-guide.md`) with Schrems II/NSM compliance docs. npm publish preparation (`files` whitelist). 1264 tests. |

# /security ide-scan
|
||||
|
||||
Scan installed IDE extensions (VS Code + forks like Cursor/Windsurf/VSCodium/code-server; JetBrains is v1.1 stub).
|
||||
|
||||
Runs the IDE scanner plus reused scanners (UNI, ENT, NET, TNT, MEM, SCR) per extension. Offline by default.
|
||||
|
||||
## Step 1: Run Scanner
|
||||
|
||||
Run the IDE extension scanner:
|
||||
|
||||
```
|
||||
node <this plugin's scanners/ide-extension-scanner.mjs> [target]
|
||||
```
|
||||
|
||||
Arguments (pass through as provided by the user):
|
||||
- `[target]` — omit, `.`, or `all` to discover all installed extensions. Absolute path to an extracted extension directory for single-scan mode.
|
||||
- `--vscode-only` / `--intellij-only` — restrict discovery
|
||||
- `--include-builtin` — include Microsoft builtin extensions (default: excluded)
|
||||
- `--online` — enable Marketplace/OSV.dev lookups (opt-in; default: fully offline)
|
||||
- `--format compact|json` — output format
|
||||
- `--fail-on <severity>` — exit 1 if findings at/above severity
|
||||
|
||||
Parse the JSON output. The result contains:
|
||||
- `meta.scanner`, `meta.version`, `meta.target`, `meta.extensions_discovered` (per type), `meta.roots_scanned`, `meta.warnings`
|
||||
- `extensions[]` — per-extension results with `id`, `version`, `type`, `publisher`, `source`, `is_builtin`, `signed`, `scanner_results` (IDE/UNI/ENT/NET/TNT/MEM/SCR), `aggregate` (counts, risk_score, risk_band, verdict), `warnings`
|
||||
- `aggregate` — top-level counts, risk_score, risk_band, verdict, extensions_total, extensions_blocked, extensions_warning
|
||||
|
||||
## Step 2: Format Report
|
||||
|
||||
Present the results:
|
||||
|
||||
```
|
||||
# IDE Extension Scan
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Scanner** | ide-extension-scanner v[version] |
|
||||
| **Target** | [target] |
|
||||
| **Roots** | [comma-separated roots_scanned] |
|
||||
| **Extensions** | [vscode] VS Code, [jetbrains] JetBrains |
|
||||
| **Top Verdict** | [ALLOW/WARNING/BLOCK] |
|
||||
| **Risk** | [risk_score]/100 ([risk_band]) |
|
||||
| **Duration** | [duration_ms]ms |
|

## Counts
|
||||
|
||||
crit=[N] high=[N] medium=[N] low=[N] info=[N]
|
||||
|
||||
## Per-Extension Results
|
||||
|
||||
[One row per extension, sorted: BLOCK first, then WARNING, then ALLOW with findings]
|
||||
|
||||
| Extension | Version | Source | Verdict | Risk | Top Issue |
|
||||
|-----------|---------|--------|---------|------|-----------|
|
||||
|
||||
Omit ALLOW rows with zero findings unless the user passed `--verbose`.
|
||||
|
||||
## Top Findings
|
||||
|
||||
[For each extension with verdict != ALLOW, list up to 3 findings as:
|
||||
- [SEV] [SCANNER]: title — file:line — recommendation]
|
||||
|
||||
## Warnings
|
||||
|
||||
[Any top-level or per-extension `warnings` entries, if present]
|
||||
```
|
||||
|
||||
## Step 3: Recommendations
|
||||
|
||||
- `aggregate.verdict === 'BLOCK'`: "One or more extensions are block-listed. Uninstall immediately — `code --uninstall-extension <id>`."
|
||||
- `aggregate.verdict === 'WARNING'`: "High/medium findings detected. Review the Top Findings list. Audit suspicious extensions before continuing."
|
||||
- `aggregate.verdict === 'ALLOW'` and counts.info > 0: "Extensions look clean. Info-level findings are observational only."
|
||||
- `aggregate.extensions_total === 0`: "No extensions discovered. Run `code --list-extensions` to confirm, or pass a specific path."
|
||||
|
||||
If the user has many sideloaded (`source=vsix`) extensions: suggest re-installing from Marketplace where possible.
|
||||
|
||||
## Notes
|
||||
|
||||
- First run with no `--online` is fully offline.
|
||||
- JetBrains discovery is deferred to v1.1 (see `knowledge/ide-extension-threat-patterns.md`).
|
||||
- Pass a single extracted extension directory to scan just one extension.

# IDE Extension Threat Patterns
|
||||
|
||||
Detection categories used by `scanners/ide-extension-scanner.mjs` (prefix `IDE`).
|
||||
Based on Koi Security / ExtensionTotal research 2024-2026 and VS Code / JetBrains official documentation.
|
||||
|
||||
Research brief: `/Users/ktg/.claude/plans/research-ide-extension-prescan.md`.
|
||||
|
||||
## Scope
|
||||
|
||||
MVP (v6.3.0): VS Code + forks (Cursor, Windsurf, VSCodium, code-server, Insiders, Remote-SSH).
|
||||
IntelliJ plugins deferred to v1.1 — JetBrains manual-review + opt-in signing reduces public case-study volume.
|
||||
|
||||
## 1. Blocklist Match (CRITICAL)
|
||||
|
||||
**Signal:** Extension ID (lowercased `publisher.name`) matches entry in `knowledge/top-vscode-extensions.json` `blocklist` array.
|
||||
|
||||
**Case:** TigerJack (11 malicious extensions, 17K+ installs). WhiteCobra (24 extensions, ~$500K crypto theft). VS Code Cryptojacking Campaign ("Mark H" impersonator, 1M+ installs). Known-malicious IDs are CRITICAL.
|
||||
|
||||
**Format:** `publisher.name@version` or `publisher.name@*` for any version.
|
||||
|
||||
**OWASP:** LLM03 (Supply Chain), ASI04.
|
||||
|
||||
## 2. Theme-with-Code (HIGH)
|
||||
|
||||
**Signal:** `package.json` `categories` includes `"Themes"` AND (`main` is truthy OR `activationEvents` non-empty).
|
||||
|
||||
**Case:** "A Wolf in Dark Mode" — the Material Theme malware. Popular theme with hidden malware under color-scheme. Pure themes require zero runtime code; any `main`/`activationEvents` on a theme is a strong red flag.
|
||||
|
||||
**OWASP:** LLM06 (Excessive Agency), ASI02.
|
||||
|
||||
## 3. Sideload Signal (HIGH unsigned, MEDIUM signed)
|
||||
|
||||
**Signal:** `extensions.json` entry has `metadata.source === "vsix"` (i.e. installed from file, not Marketplace).
|
||||
|
||||
**Rationale:** Marketplace signature verification and malware-scan bypassed for `.vsix`-file installs. Legitimate use cases exist (private extensions, dev testing), but high malware-ratio in observed incidents.
|
||||
|
||||
**Modifier:** If `.signature.p7s` file present in extension root → downgrade to MEDIUM (possibly Marketplace-downloaded .vsix).
|
||||
|
||||
**OWASP:** LLM03.
|
||||
|
||||
## 4. Broad Activation Surface (MEDIUM / LOW)
|
||||
|
||||
**Signal:** `package.json` `activationEvents` includes `"*"` (MEDIUM) or `"onStartupFinished"` (LOW).
|
||||
|
||||
**Rationale:** "Wants to run always" is a strong capability signal — necessary for a few legitimate tools (shell integrators, system monitors) but unusual for most extensions. Exemption: exact-match against top-100 list.
|
||||
|
||||
**Note:** VS Code 1.74+ no longer requires `activationEvents` for declarative `contributes` — absence of events is NOT suspicious.
|
||||
|
||||
**OWASP:** LLM06.
|
||||
|
||||
## 5. Typosquat (HIGH / MEDIUM)
|
||||
|
||||
**Signal:** Extension ID has Levenshtein distance ≤ 2 from a top-100 extension ID, excluding exact match.
|
||||
|
||||
- Distance 1 → HIGH
|
||||
- Distance 2 AND target is in top-50 → MEDIUM
|
||||
|
||||
**Case:** TigerJack aliases `ab-498`, `498`, `498-00` targeting popular AI / utility extensions. Publisher impersonation (e.g. `ms-pythom.pythom` vs `ms-python.python`). AI-assistant typosquats (`claude-code`, `codeium`, `cody`).
|
||||
|
||||
**OWASP:** LLM03.
|
||||
|
||||
## 6. Extension Pack Expansion (MEDIUM)
|
||||
|
||||
**Signal:** `package.json` `extensionPack` array contains ≥ 3 bundled extension IDs.
|
||||
|
||||
**Rationale:** Extension packs amplify trust chain — installing one extension installs N others, each of which brings its own risk surface.
|
||||
|
||||
**OWASP:** LLM03.
|
||||
|
||||
## 7. Dangerous Uninstall Hook (HIGH / LOW)
|
||||
|
||||
**Signal:** `package.json` `scripts["vscode:uninstall"]` exists AND references one of: `child_process`, `curl`, `wget`, `rm`, `powershell`, `iex`, `Invoke-Expression`, `Start-Process`.
|
||||
|
||||
**Rationale:** Uninstall scripts are a persistence hook — attacker can delay destructive payload to trigger on uninstall attempt. VS Code runs these scripts with the user's privileges.
|
||||
|
||||
**OWASP:** LLM06, ASI02.
|
||||
|
||||
## 8. Data Exfiltration Patterns (delegated)
|
||||
|
||||
Detected by reused scanners on extension bundled source:
|
||||
|
||||
- **Hardcoded webhooks** (Discord, Pipedream, webhook.site, Burp Collaborator, interactsh) → detected by NET scanner
|
||||
- **Base64-encoded C2 domains** → detected by ENT scanner
|
||||
- **Unicode Tag steganography** (GlassWorm pattern) → detected by UNI scanner
|
||||
- **Env var exfiltration** (`process.env.HOME`, SSH keys, `.aws/credentials`, `.env`) → detected by TNT scanner
|
||||
- **Clipboard / screen capture misuse** → detected by NET + TNT via API surface
|
||||
|
||||
**Cases:** GlassWorm (Unicode steganography + blockchain C2), MaliciousCorgi (AI-assistant data leaks), VS Code Cryptojacking (PowerShell download-and-execute), screen-capture malware ("Bitcoin Black", "Codo AI").
|
||||
|
||||
**OWASP:** LLM01 (Prompt Injection), LLM02 (Sensitive Disclosure), LLM03.
|
||||
|
||||
## 9. Nested npm Supply Chain (delegated)
|
||||
|
||||
Detected by SCR scanner on extension's bundled `package-lock.json` or flat `package.json` dependencies.
|
||||
|
||||
**Rationale:** A typical VS Code extension with `main` bundles 50–500+ transitive npm deps. VS Code Marketplace malware-scan does NOT inspect nested deps. Compromised npm packages (event-stream, rc, nx, ua-parser-js, lottie-player) flow into extensions automatically at build time.
|
||||
|
||||
**OWASP:** LLM03, ASI04.
|
||||
|
||||
## 10. Memory Poisoning via README / CHANGELOG (delegated)
|
||||
|
||||
Detected by MEM scanner on extension `README.md` and `CHANGELOG.md`.
|
||||
|
||||
**Rationale:** Extension README is displayed in VS Code when user inspects extension details. Prompt-injection payloads in README can poison co-located LLM assistants (Copilot, Claude Code) if the user asks about the extension.
|
||||
|
||||
**OWASP:** LLM01.
|
||||
|
||||
## Known Limitations
|
||||
|
||||
- No bytecode analysis of IntelliJ JARs (v1.1+)
|
||||
- No VSIX extraction (pass extracted directory instead)
|
||||
- No Marketplace API lookups without `--online` flag (publisher age, download count, verified status unavailable offline)
|
||||
- Profile-specific extension filtering not implemented (all installed extensions are scanned)
|
||||
- `.obsolete` file parsing not implemented (extensions marked obsolete are still scanned — harmless but redundant)
|
||||
- Real-time IDE hooks are out of scope (separate repo, planned)
