A package installation can alter multiple AI-agent instruction surfaces and run remote code without an explicit setup command. - **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:** 0.1.6 - **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. On npm installation, the package overwrites skills in broad, foreign AI-agent control surfaces. It also downloads and executes an opaque remote native binary during installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T00:06:28.834Z - **Finished:** 2026-09-14T00:07:25.823Z - **Download time:** 1032 ms - **Static scan time:** 104 ms - **AI review time:** 55852 ms - **Total time:** 56989 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:** On npm installation, the package overwrites skills in broad, foreign AI-agent control surfaces. It also downloads and executes an opaque remote native binary during installation. - **Trigger:** npm install, including transitive installation that runs postinstall. - **Impact:** A package installation can alter multiple AI-agent instruction surfaces and run remote code without an explicit setup command. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T00:07:25.823Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic agent-skill overwrite plus remote binary download and execution. - **Attack narrative:** Installing the package invokes its postinstall hook. The hook deletes and replaces a named skill directory across many unrelated AI-agent products, creating a fallback agent directory if none exists. It also retrieves an archive from a remote CDN, extracts a native executable, copies it into the package, and runs it. The checksum is obtained from the same downloaded archive, so it does not establish independent provenance. - **Rationale:** This is an unconsented postinstall mutation of broad foreign AI-agent control surfaces, combined with automatic remote native-code execution. It meets the install-hook abuse blocking policy. - **Files touched:** scripts/install.js, skills/yzj-cli, bin/yzj-cli, ~/.agents/skills/yzj-cli, ~/.claude/skills/yzj-cli, ~/.cursor/skills/yzj-cli, ~/.gemini/skills/yzj-cli, ~/.codex/skills/yzj-cli, ~/.github/skills/yzj-cli, ~/.windsurf/skills/yzj-cli, ~/.cline/skills/yzj-cli, ~/.trae/skills/yzj-cli, ~/.hermes/skills/yzj-cli - **Network endpoints:** https://www.yunzhijia.com/mixed/yzj-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **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 overwrites and copies skills into multiple unrelated AI-agent directories under the home directory., It creates a .agents skill directory even when no supported agent directory exists., The postinstall downloads a remote archive, installs its binary, and executes that binary during installation. - **Evidence against:** The installer restricts the initial download host to an allowlist., No source-level credential harvesting or exfiltration was found in the inspected JavaScript. ## Affected versions and remediation This report applies to @yunzhijia/cli@0.1.6. - Avoid installing @yunzhijia/cli@0.1.6. 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.
