Unconsented agent behavior changes and remote third-party code introduction. - **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:** 4.2.0 - **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. This is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, which meets the blocking policy. No exfiltration is needed for this verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-08-08T13:18:48.524Z - **Finished:** 2026-08-08T13:19:21.655Z - **Download time:** 252 ms - **Static scan time:** 72 ms - **AI review time:** 32806 ms - **Total time:** 33131 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:** npm postinstall automatically detects and mutates multiple third-party AI-agent skill directories. It also retrieves and installs unpinned external code. - **Trigger:** npm installation of onemanagency@4.2.0 - **Impact:** Unconsented agent behavior changes and remote third-party code introduction. - **Evidence paths:** package.json, build/postinstall.js, build/installer.js, bin/oma.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T13:19:21.655Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall propagation into detected AI-agent control surfaces - **Attack narrative:** Installing the package triggers build/postinstall.js without a user command. It invokes installAll, which detects numerous AI-agent configuration homes and overwrites this package's skills into their skill directories; it additionally installs global npm packages and clones mutable external repositories by default. - **Rationale:** This is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, which meets the blocking policy. No exfiltration is needed for this verdict. - **Files touched:** ~/.oma/, ~/.claude/skills/, ~/.codex/skills/, ~/.cursor/skills/, ~/.gemini/skills/, ~/.gemini/antigravity/skills/ - **Network endpoints:** https://github.com/voltagent/awesome-design-md.git, https://github.com/coreyhaines31/marketingskills.git, https://github.com/anthropics/skills.git ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs postinstall automatically., build/postinstall.js calls installAll during npm install., build/installer.js copies skills into detected ~/.claude, ~/.codex, ~/.cursor, ~/.gemini and other agent directories., Installer also installs global npm CLIs and clones mutable external Git repositories. - **Evidence against:** No credential harvesting or exfiltration code found in inspected runtime files., CLI's explicit install command offers --no-external, but postinstall does not use it. ## Affected versions and remediation This report applies to onemanagency@4.2.0. - Avoid installing onemanagency@4.2.0. 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.
