The package gains automatic execution in Claude Code sessions and records session event data in the user's Claude configuration area. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm install automatically rewrites Claude Code's shared hook configuration. The added hooks run on many Claude Code events, collect event payloads, and launch a detached worker. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-09T10:31:32.680Z - **Finished:** 2026-09-09T10:32:31.493Z - **Download time:** 258 ms - **Static scan time:** 917 ms - **AI review time:** 57637 ms - **Total time:** 58813 ms The recorded confidence comes from the underlying analysis.

The added hooks run on many Claude Code events, collect event payloads, and launch a detached worker. - **Trigger:** npm install -g syndes, unless an environment guard suppresses postinstall. - **Impact:** The package gains automatic execution in Claude Code sessions and records session event data in the user's Claude configuration area. - **Evidence paths:** package.json, bin/postinstall.mjs, src/install.mjs, src/settings.mjs, runtime/hook.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-09T10:32:31.493Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of Claude Code settings to register persistent command hooks. - **Attack narrative:** Installing this package globally triggers postinstall, which invokes its installer without requiring the user to run syndes install. The installer copies code into the Claude configuration directory and adds command hooks to shared Claude Code settings for numerous events. Each invoked hook reads the event payload, writes it to a local spool, and can start a detached worker. This is an automatic, foreign AI-agent control-surface modification rather than an explicit user-command setup. - **Rationale:** The global-only guard reduces scope but does not obtain explicit consent before postinstall rewrites Claude Code's shared settings and installs persistent hooks. This meets the policy for unconsented install-time mutation of a foreign AI-agent control surface. - **Files touched:** ~/.claude/settings.json, ~/.claude/settings.json.syndes-backup, ~/.claude/hooks/syndes, ~/.claude/syndes/spool ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically., On global installation, that script calls the installer without an explicit setup command., The installer modifies Claude Code's settings to add command hooks for every configured event., Those hooks capture Claude Code event payloads, store them under the user's Claude directory, and start a detached worker. - **Evidence against:** The lifecycle script skips local installs, CI, dry runs, and an opt-out environment variable., No automatic network endpoint or self-dependency was found; team sharing requires later configuration. ## Affected versions and remediation This report applies to syndes@0.3.0. - Avoid installing syndes@0.3.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
