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. Installation changes AI client behavior and enables the registered WoWok MCP server for affected clients. - **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:** 3.3.0 - **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. The npm postinstall automatically mutates user-level configuration for multiple AI clients and registers an MCP server by default. This meets the policy for blocking unconsented install-time changes to a broad AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-08T09:40:21.398Z - **Finished:** 2026-10-08T09:40:47.075Z - **Download time:** 1032 ms - **Static scan time:** 434 ms - **AI review time:** 24210 ms - **Total time:** 25677 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 postinstall hook modifies user-level AI client skill and MCP configuration. It registers the package’s MCP server across automatically resolved client targets by default. - **Trigger:** Installing the package through npm, which invokes postinstall. - **Impact:** Installation changes AI client behavior and enables the registered WoWok MCP server for affected clients. - **Evidence paths:** package.json, scripts/install.js, dist/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T09:40:47.075Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle handler installs skill files for resolved user targets and, unless opted out, ensures an MCP server and registers it in client configuration files. - **Attack narrative:** The package’s automatic postinstall writes skills and MCP server registration into user-level AI client configurations. The registration is on by default; an environment variable can disable MCP management. This is an unconsented install-time change to AI-agent control surfaces. - **Rationale:** The npm postinstall automatically mutates user-level configuration for multiple AI clients and registers an MCP server by default. This meets the policy for blocking unconsented install-time changes to a broad AI-agent control surface. - **Files touched:** package.json, scripts/install.js, dist/installer.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 scripts/install.js from postinstall., The postinstall handler installs skills for automatically resolved user targets., Unless an environment variable disables it, postinstall checks and registers an MCP server in client configuration files., The installer writes an MCP server command and arguments into client configuration. - **Evidence against:** The installer’s MCP registration has an opt-out environment variable, but registration is enabled by default. ## Affected versions and remediation This report applies to @wowok/skills@3.3.0. - Avoid installing @wowok/skills@3.3.0. 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.
