The package changes files that guide AI-agent behavior across multiple tools. - **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:** 0.3.1 - **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. LPM flags this version as an AI-agent control-surface risk. The npm postinstall hook modifies AI-agent configuration in user and project locations without an interactive consent step. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-07T08:36:13.517Z - **Finished:** 2026-10-07T08:36:54.369Z - **Download time:** 1282 ms - **Static scan time:** 135 ms - **AI review time:** 39434 ms - **Total time:** 40852 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 modifies AI-agent configuration in user and project locations without an interactive consent step. - **Trigger:** Installing the package through npm, which invokes its postinstall script. - **Impact:** The package changes files that guide AI-agent behavior across multiple tools. - **Evidence paths:** package.json, bin/inboost-proxy.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T08:36:54.369Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The handler calls the IDE skill installer, which writes skill and command files and appends instructions to agent configuration. - **Attack narrative:** During npm installation, the postinstall handler runs the skill installer silently. That installer writes agent skills and commands and appends instructions to global Claude configuration, with corresponding writes for other agent tools. This is unconsented mutation of broad AI-agent control surfaces. - **Rationale:** The manifest's postinstall hook reaches code that automatically writes to multiple AI-agent configuration locations without a consent prompt. This meets the block criterion for unconsented install-time mutation of foreign or broad agent control surfaces. - **Files touched:** package.json, bin/inboost-proxy.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs the CLI with a postinstall hook., The postinstall handler automatically installs agent files without prompting., Installation writes skill files and appends instructions to global Claude configuration. - **Evidence against:** The CLI presents itself as an AI proxy and installer for IDE integrations., The inspected excerpts establish agent configuration mutation, but do not establish credential theft or remote code execution. ## Affected versions and remediation This report applies to @inboost-pro/inboost-ai-proxy@0.3.1. - Avoid installing @inboost-pro/inboost-ai-proxy@0.3.1. 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.
