Installation can silently replace AI-agent skill content across multiple agent control surfaces. - **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:** 0.5.18 - **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 postinstall hook mutates multiple AI-agent skill locations without an explicit user command. It replaces existing lj-awb skill directories with package-provided content. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-28T08:28:37.347Z - **Finished:** 2026-09-28T08:29:29.053Z - **Download time:** 515 ms - **Static scan time:** 1067 ms - **AI review time:** 50123 ms - **Total time:** 51706 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 mutates multiple AI-agent skill locations without an explicit user command. It replaces existing lj-awb skill directories with package-provided content. - **Trigger:** Installing the npm package triggers the postinstall hook. - **Impact:** Installation can silently replace AI-agent skill content across multiple agent control surfaces. - **Evidence paths:** package.json, install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T08:29:29.053Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook selects default cc-switch, Codex, and Claude skill paths, recursively removes each target, then copies the bundled skill directory. - **Attack narrative:** A registry installation automatically invokes install.mjs. Unless an environment override is supplied, it writes into cc-switch, Codex, and Claude skill directories. Before copying its own skill bundle, it recursively force-removes each existing target. This is an unconsented postinstall mutation of broad AI-agent control surfaces. - **Rationale:** The package has a concrete automatic lifecycle hook that force-replaces skill directories for several unrelated AI-agent environments. This meets the install-control-surface blocking policy even though the hook does not show network exfiltration. - **Files touched:** ~/.cc-switch/skills/lj-awb, $CODEX\_HOME/skills/lj-awb, ~/.claude/skills/lj-awb ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs install.mjs after installation., The installer targets skill directories for cc-switch, Codex, and Claude when no explicit destination is set., The installer forcibly deletes each target directory and copies its bundled skill into it. - **Evidence against:** No network transmission or credential collection was identified in the installation hook. ## Affected versions and remediation This report applies to @lingjingai/lj-awb-cli-pre@0.5.18. - Avoid installing @lingjingai/lj-awb-cli-pre@0.5.18. 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.
