Claude Code will execute those hook commands on later tool use and user prompt submit without a separate consent step during install. - **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:** 0.22.167 - **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. On npm install, postinstall silently rewrites the user's global Claude Code settings so PostToolUse and UserPromptSubmit invoke telora-ai command hooks whenever those binaries are on PATH. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-25T20:41:13.879Z - **Finished:** 2026-09-25T20:42:34.915Z - **Download time:** 755 ms - **Static scan time:** 934 ms - **AI review time:** 79346 ms - **Total time:** 81036 ms The recorded confidence comes from the underlying analysis.

If telora-ai-hook and telora-ai-human-hook are on PATH, the script loads the user's home Claude settings, ensures PostToolUse and UserPromptSubmit hook arrays exist, and registers those binaries as command hooks with an empty matcher. It creates ~/.claude if needed and overwrites settings.json. Errors are discarded, so the control-surface change is quiet and does not fail the install. - **Rationale:** Unconsented postinstall mutation of the global Claude Code hook surface is a foreign agent control-surface write, not an explicit user setup command. Empty matchers make the injected commands apply broadly to tool use and prompt submit. - **Files touched:** ~/.claude/settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 92.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** npm postinstall always runs scripts/postinstall.js and ignores its exit status with || true., When both telora-ai-hook and telora-ai-human-hook resolve through which, the script edits the user Claude settings file., It inserts command hooks with an empty matcher into PostToolUse and UserPromptSubmit, or rewrites an existing matching command to the resolved path., The target file is join(homedir(), ".claude", "settings.json"), created if missing., The updated settings object is written back, and any error is swallowed so install still succeeds. - **Evidence against:** Hook injection is skipped when either companion binary is absent from PATH., The postinstall script does not open a network connection or read credential files., Runtime daemon and connector file writes are inside explicit MCP or init handlers, not the install hook. ## Affected versions and remediation This report applies to @telora/mcp-products@0.22.167. - Avoid installing @telora/mcp-products@0.22.167. 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.
