Installing this dependency can alter broad AI-agent control surfaces without an explicit user command. - **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:** 3.2.4 - **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. Automatic installation changes AI-client skill and MCP configuration. It also installs and launches a separate MCP package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-28T05:57:42.589Z - **Finished:** 2026-09-28T05:58:49.895Z - **Download time:** 772 ms - **Static scan time:** 385 ms - **AI review time:** 66148 ms - **Total time:** 67306 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:** Automatic installation changes AI-client skill and MCP configuration. It also installs and launches a separate MCP package. - **Trigger:** npm postinstall - **Impact:** Installing this dependency can alter broad AI-agent control surfaces without an explicit user command. - **Evidence paths:** package.json, scripts/install.js, dist/installer.js, dist/targets.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T05:58:49.895Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle handler writes user-target skills, globally installs @wowok/agent-mcp, and registers its launcher in client MCP configuration. - **Attack narrative:** The package's postinstall hook automatically invokes an installer. That installer targets user AI-client locations, installs a separate MCP package globally, and registers the MCP launcher in client configuration files, including Codex configuration. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The automatic lifecycle chain performs broad AI-agent configuration mutation and installs an additional executable MCP dependency. This meets the install-control-surface blocking rule. - **Files touched:** package.json, scripts/install.js, dist/installer.js, dist/targets.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall hook., The lifecycle shim invokes the installer during the npm lifecycle event., Postinstall installs skills into all resolved user client targets., Postinstall globally installs a separate MCP package and registers it in client configuration files., The target definitions include user and project Codex MCP configuration paths. ## Affected versions and remediation This report applies to @wowok/skills@3.2.4. - Avoid installing @wowok/skills@3.2.4. 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.
