It can alter the instructions and capabilities available to several installed AI-agent tools without the user's consent. - **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:** 0.1.4 - **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. An automatic npm lifecycle hook modifies AI-agent skill control surfaces in the user's home directory. No user command or opt-in is required for this mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-22T03:38:12.745Z - **Finished:** 2026-09-22T03:39:01.234Z - **Download time:** 1037 ms - **Static scan time:** 78 ms - **AI review time:** 47373 ms - **Total time:** 48489 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:** An automatic npm lifecycle hook modifies AI-agent skill control surfaces in the user's home directory. No user command or opt-in is required for this mutation. - **Trigger:** Installing the package runs its postinstall hook. - **Impact:** It can alter the instructions and capabilities available to several installed AI-agent tools without the user's consent. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T03:39:01.234Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook deletes and copies a package skill into detected directories for multiple AI-agent products, or creates a fallback agent skill directory. - **Attack narrative:** During npm installation, the package automatically runs an installer. That installer discovers multiple AI-agent skill locations below the user's home directory, removes any existing yzj-cli skill there, and replaces it with the package's skill content. It performs this across several unrelated agent products and creates a fallback agent directory if none are detected. This is an unconsented, broad AI-agent control-surface mutation at install time. - **Rationale:** The postinstall hook performs cross-product AI-agent skill deployment into home-directory control surfaces. This meets the blocking policy for unconsented install-time mutation of a foreign or broad AI-agent control surface. - **Files touched:** scripts/install.js - **Network endpoints:** https://www.yunzhijia.com/mixed/yzj-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs scripts/install.js automatically through postinstall., The installer targets skill directories for numerous unrelated AI-agent products in the user's home directory., The postinstall code removes and replaces a yzj-cli skill in each detected agent directory, and creates a fallback agent skill directory when none is found., Installation invokes that cross-agent skill deployment after downloading or when its binary already exists. - **Evidence against:** The installer checks the initial download hostname against an allowlist, although redirects are followed. ## Affected versions and remediation This report applies to @yunzhijia/cli@0.1.4. - Avoid installing @yunzhijia/cli@0.1.4. 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.
