Changes shared agent instructions and capabilities outside the package directory. No credential theft was established. - **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:** 2026.8.20 - **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. The npm postinstall hook automatically installs external skills into a shared AI-agent control surface without affirmative consent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-01T08:06:03.359Z - **Finished:** 2026-10-01T08:08:13.934Z - **Download time:** 8177 ms - **Static scan time:** 42086 ms - **AI review time:** 80310 ms - **Total time:** 130575 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 npm postinstall hook automatically installs external skills into a shared AI-agent control surface without affirmative consent. - **Trigger:** Installing the published package when Lark skills are absent and the opt-out environment variable is unset. - **Impact:** Changes shared agent instructions and capabilities outside the package directory. No credential theft was established. - **Evidence paths:** package.json, scripts/postinstall-bundled-plugins.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-01T08:08:13.934Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script invokes npx with automatic approval and global installation flags for all larksuite/cli skills. - **Attack narrative:** An ordinary npm installation launches the postinstall script, which automatically invokes the external skills installer from the user's home directory. It adds all larksuite/cli skills globally, targeting the shared agent skills directory. Existing-install checks and an opt-out variable limit activation but do not establish consent for this broad agent configuration mutation. - **Rationale:** The inspected lifecycle chain performs unconsented install-time mutation of a broad AI-agent control surface, meeting the supplied blocking policy. The separate guarded runtime integrations do not neutralize that automatic behavior. - **Files touched:** ~/.agents/skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs scripts/postinstall-bundled-plugins.mjs after npm installation., The lifecycle script directly calls installLarkCliSkills without a consent prompt., The installer targets the shared ~/.agents/skills directory; disabling it requires an environment-variable opt-out., The installer runs npx with automatic approval to add all larksuite/cli skills globally from the user's home directory. - **Evidence against:** Installation skips source checkouts and systems where Lark skills are already present., The flagged runtime plugin command requires authorization and administrator scope; the flagged compaction code reads workspace AGENTS.md rather than modifying it. ## Affected versions and remediation This report applies to kaijibot@2026.8.20. - Avoid installing kaijibot@2026.8.20. 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.
