Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Soft block: AI-agent control surface** — Warn by default; block when configured. Agent behavior can be changed without an affirmative setup action from the installer. - **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:** 0.3.3 - **Selected version is latest:** Yes - **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. The manifest activates a postinstall routine that automatically writes package-provided instructions into global and project AI-agent configuration. This is unconsented lifecycle mutation of a broad agent control surface, supporting a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-19T13:14:21.814Z - **Finished:** 2026-10-19T13:18:17.937Z - **Download time:** 1022 ms - **Static scan time:** 138 ms - **AI review time:** 234961 ms - **Total time:** 236123 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 automatic install hook changes global and project AI-agent configuration by installing skills and adding instructions. - **Trigger:** Installing the package through npm, which runs its postinstall hook. - **Impact:** Agent behavior can be changed without an affirmative setup action from the installer. - **Evidence paths:** package.json, bin/inboost-proxy.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T13:18:17.937Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook calls installIDESkills, which writes and appends package-provided content to Claude and other agent configuration paths. - **Attack narrative:** On npm installation, the package's postinstall hook invokes its entrypoint with --postinstall. That path calls installIDESkills, which writes skills and commands and appends instructions under global and project agent configuration directories. The configuration changes occur without an affirmative setup action, creating an unconsented AI-agent control surface. - **Rationale:** The manifest activates a postinstall routine that automatically writes package-provided instructions into global and project AI-agent configuration. This is unconsented lifecycle mutation of a broad agent control surface, supporting a block. - **Files touched:** package.json, bin/inboost-proxy.js ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json defines a postinstall hook that invokes the entrypoint with --postinstall., The --postinstall path calls installIDESkills(false) automatically., The installer writes skill and command files and appends instructions to global and project Claude configuration., The write helpers create directories and write or append configuration content. ## Affected versions and remediation This report applies to @inboost-pro/inboost-proxy@0.3.3. - Avoid installing @inboost-pro/inboost-proxy@0.3.3. 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.
