It mutates foreign AI-agent control surfaces without a user command and can cause further package installation. - **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:** 0.5.9 - **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. Installing the package automatically replaces skill directories used by multiple AI-agent products. Those injected instructions can later trigger a global npm installation when an agent uses the skill. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T12:54:51.055Z - **Finished:** 2026-09-12T12:55:59.101Z - **Download time:** 765 ms - **Static scan time:** 975 ms - **AI review time:** 66305 ms - **Total time:** 68046 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 replaces skill directories used by multiple AI-agent products. Those injected instructions can later trigger a global npm installation when an agent uses the skill. - **Trigger:** npm installation runs postinstall; later AI-agent use of the copied skill invokes its bootstrap script. - **Impact:** It mutates foreign AI-agent control surfaces without a user command and can cause further package installation. - **Evidence paths:** package.json, install.mjs, skills/lj-awb/scripts/resolve-lj-awb-cmd.sh - **Review source:** ai\_review - **Reviewed:** 2026-09-12T12:55:59.101Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-agent skill replacement and bootstrap installation. - **Attack narrative:** The package runs install.mjs automatically during npm installation. Unless an environment variable is set, it force-removes and replaces skill directories for Codex, Claude, and cc-switch. The copied skill tells an agent to run a bootstrap script; if the CLI is absent or old, that script runs npm install -g for this package. This creates an unconsented cross-agent persistence and installation path. - **Rationale:** This is a concrete postinstall mutation of foreign AI-agent control surfaces, followed by an automatic package-install path. The behavior meets the install-hook abuse blocking policy despite being unobfuscated. - **Files touched:** skills/lj-awb, ~/.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 manifest automatically runs the installer after npm installation., The installer targets Codex, Claude, and cc-switch skill directories without an explicit user command., It forcibly deletes each existing lj-awb skill directory before copying its bundled agent instructions., The installed skill can automatically run a global npm install when an agent first uses it. - **Evidence against:** The installer is readable JavaScript with no obfuscation or hidden network request., The reviewed API client sends its access key only to the configured product API during user-invoked CLI operations. ## Affected versions and remediation This report applies to @lingjingai/lj-awb-cli@0.5.9. - Avoid installing @lingjingai/lj-awb-cli@0.5.9. 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.
