This can alter how installed AI coding agents behave in user and project contexts without consent. - **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 silently installs behavior-bearing instructions into AI-agent configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-07T08:24:53.555Z - **Finished:** 2026-10-07T08:25:16.698Z - **Download time:** 513 ms - **Static scan time:** 137 ms - **AI review time:** 22492 ms - **Total time:** 23143 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 silently installs behavior-bearing instructions into AI-agent configuration. - **Trigger:** Installing the package through npm, which invokes its postinstall script. - **Impact:** This can alter how installed AI coding agents behave in user and project contexts without consent. - **Evidence paths:** package.json, bin/inboost-proxy.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T08:25:16.698Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler calls installIDESkills, which writes or appends skill, command, and rules files under the user's home directory and the current project. - **Attack narrative:** On npm installation, the postinstall script invokes the CLI with --postinstall. The handler calls installIDESkills, which writes or appends instructions across global and project AI-agent configuration locations. The package therefore creates an unconsented agent control surface during installation. - **Rationale:** The postinstall hook reaches code that mutates broad AI-agent configuration locations without a consent prompt. This meets the blocking policy for unconsented installation-time control-surface mutation. - **Files touched:** package.json, bin/inboost-proxy.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs the CLI with --postinstall during npm installation., The postinstall handler immediately calls installIDESkills without checking for user consent., That installer writes and appends agent instructions in global and project configuration locations, including Claude, Cursor, and OpenHands. ## Affected versions and remediation This report applies to @inboost-pro/inboost-ai-proxy@0.3.0. - Avoid installing @inboost-pro/inboost-ai-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.
