The installation can change how supported coding agents behave in the user's home directory and current project. - **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. The npm postinstall hook automatically installs agent instructions and configuration into global and project-level control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-07T06:30:07.785Z - **Finished:** 2026-10-07T06:30:29.967Z - **Download time:** 509 ms - **Static scan time:** 137 ms - **AI review time:** 21535 ms - **Total time:** 22182 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The npm postinstall hook automatically installs agent instructions and configuration into global and project-level control surfaces. - **Trigger:** Installing the package through npm triggers its postinstall script. - **Impact:** The installation can change how supported coding agents behave in the user's home directory and current project. - **Evidence paths:** package.json, bin/inboost-proxy.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T06:30:29.967Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler calls installIDESkills, which writes skill and command files and appends instructions across multiple agent-specific directories without requesting consent. - **Attack narrative:** During npm installation, the postinstall handler calls installIDESkills. That function writes and appends agent-facing skills, commands, and rules in global and project-level directories for multiple tools. This creates a broad, unconsented agent control-surface mutation. - **Rationale:** The package's postinstall hook reaches code that silently writes instructions and configuration across multiple AI-agent control surfaces. This meets the blocking policy for unconsented install-time mutation of broad agent configuration. - **Files touched:** package.json, bin/inboost-proxy.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs the entrypoint with --postinstall during installation., The postinstall handler invokes installIDESkills without a user prompt., That installer writes or appends agent instructions and configuration across global and project-level Claude, Cursor, and OpenHands locations. ## Affected versions and remediation This report applies to inboost-proxy@0.3.0. - Avoid installing inboost-proxy@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.
