It also removes legacy agent skills and a home-directory state directory. - **Trigger:** npm postinstall - **Impact:** Unconsented installation can alter multiple AI-agent control surfaces and replace or remove local skill state. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/bundle.js - **Review source:** ai\_review - **Reviewed:** 2026-09-20T02:52:56.443Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle hook runs the bundled skill installer with force for multiple slugs; the bundle fetches remote artifacts and distributes them across detected client directories. - **Attack narrative:** On npm installation, the package runs a postinstall hook that force-installs remotely sourced skills into a fallback agent directory and several detected third-party AI-client directories. This is a broad foreign AI-agent control-surface mutation without a user-invoked setup action. The same hook also removes legacy skills and a home-directory state directory. - **Rationale:** The complete automatic lifecycle path downloads remote content and writes it into broad AI-agent directories, while also deleting local agent-related state. This is concrete install-hook abuse rather than ordinary package setup. - **Files touched:** ~/.yunke/skillshub.json, ~/.omnicli, .agents/skills, .claude/skills, .workbuddy/skills - **Network endpoints:** https://skillshub.yunke.ai ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs a postinstall script., The postinstall script invokes skill installation for seven slugs without a user command., The bundled installer distributes downloaded skills to detected AI-client directories, including fallback .agents and several third-party client directories., The bundle obtains its API base URL from local configuration and fetches remote skill manifests and artifacts from it., The install hook deletes legacy skills and the ~/.omnicli directory during installation. ## Affected versions and remediation This report applies to @yunkeai/yunke-cli@2.0.4. - Avoid installing @yunkeai/yunke-cli@2.0.4. 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.
