Package-authored instructions become available to multiple AI-agent clients without an explicit setup 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:** 1.4.0 - **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. Installing the package automatically places its agent skill in a shared global directory and in detected third-party AI-agent directories. It also performs a default outbound update check. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T11:59:50.030Z - **Finished:** 2026-09-12T12:00:34.286Z - **Download time:** 765 ms - **Static scan time:** 72 ms - **AI review time:** 43418 ms - **Total time:** 44256 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:** Installing the package automatically places its agent skill in a shared global directory and in detected third-party AI-agent directories. It also performs a default outbound update check. - **Trigger:** npm installation invokes postinstall. - **Impact:** Package-authored instructions become available to multiple AI-agent clients without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skill.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T12:00:34.286Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic recursive deployment into global AI-agent skill directories. - **Attack narrative:** On npm installation, package.json runs scripts/install-skill.js. The script always creates and populates the shared ~/.agents skill location, then detects and populates several unrelated AI-agent configuration directories. This is an unconsented postinstall mutation of broad agent control surfaces. It also contacts GitHub for an update check unless disabled. - **Rationale:** The package uses an automatic npm lifecycle hook to copy package-controlled skill content into shared and third-party AI-agent directories. This meets the install-time AI-agent control-surface abuse boundary despite no observed secret theft or remote payload execution. - **Files touched:** skills/comsol/\*\*, ~/.agents/skills/comsol, ~/.claude/skills/comsol, ~/.cursor/skills/comsol, ~/.codex/skills/comsol, ~/.pi/agent/skills/comsol, ~/.dsh/skills/comsol - **Network endpoints:** https://raw.githubusercontent.com/2p1c/comsol-skills/master/skills/comsol/VERSION ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically runs the installer., The installer always targets the shared global agent skill directory., It also writes into detected Claude Code, Cursor, Codex, Pi, and DeepSeek skill locations., The installer recursively copies the package skill files into those agent control surfaces., The postinstall performs an outbound version check by default. - **Evidence against:** No credential collection or secret exfiltration was found., The remote request reads only a version string and does not execute its response., No runtime self-dependency, payload download, or obfuscated code was found. ## Affected versions and remediation This report applies to @2p1c/comsol-ai@1.4.0. - Avoid installing @2p1c/comsol-ai@1.4.0. 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.
