A package installation can establish or replace instructions used by several AI-agent tools 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:** 0.1.7 - **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. Installing the package automatically modifies multiple third-party AI-agent skill control surfaces in the user's home directory. It also fetches and executes a remote binary during installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-17T12:11:10.565Z - **Finished:** 2026-09-17T12:11:52.710Z - **Download time:** 510 ms - **Static scan time:** 101 ms - **AI review time:** 41532 ms - **Total time:** 42145 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 modifies multiple third-party AI-agent skill control surfaces in the user's home directory. It also fetches and executes a remote binary during installation. - **Trigger:** npm postinstall runs when the package is installed. - **Impact:** A package installation can establish or replace instructions used by several AI-agent tools without an explicit setup command. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T12:11:52.710Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall downloads a binary and forcibly replaces agent skill directories. - **Attack narrative:** A registry installation invokes scripts/install.js. The script downloads an archive containing an executable, installs it, and runs it for a version check. It then removes and copies a package-provided skill into up to ten AI-agent configuration locations under the user's home directory, including a fallback location it creates. This is unconsented postinstall mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The postinstall hook establishes or replaces skills across unrelated AI-agent products without an explicit user setup action. This meets the install-time foreign/broad AI-agent control-surface mutation block policy. - **Files touched:** scripts/install.js, package.json, 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:** 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 ten AI-agent skill locations under the user's home directory., During installation it forcibly deletes and replaces a skill directory in each detected agent location, and creates a fallback .agents directory., The lifecycle script downloads, extracts, installs, and executes a remote binary. - **Evidence against:** The download URL defaults to the vendor's Yunzhijia host and the initial host is allowlisted., The installer attempts a SHA-256 check when archive metadata supplies a checksum. ## Affected versions and remediation This report applies to @yunzhijia/cli@0.1.7. - Avoid installing @yunzhijia/cli@0.1.7. 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.
