A package install can alter an AI-agent control surface 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:** 0.2.8 - **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. A global npm install silently changes a shared AI-agent skills directory. It can remove an existing matching entry and replace it with a symlink to this package's skill content. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-06T05:27:12.597Z - **Finished:** 2026-09-06T05:28:00.399Z - **Download time:** 264 ms - **Static scan time:** 113 ms - **AI review time:** 47424 ms - **Total time:** 47802 ms The recorded confidence comes from the underlying analysis.

It can remove an existing matching entry and replace it with a symlink to this package's skill content. - **Trigger:** Global installation of the package runs postinstall. - **Impact:** A package install can alter an AI-agent control surface without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-06T05:28:00.399Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time replacement of AI-agent skill entries under the user's home directory. - **Attack narrative:** When installed globally, npm runs the postinstall script. The script creates ~/.agents/skills, removes an existing zmyt-\* entry if it is not already the expected link, and symlinks package-provided skills into that shared agent directory. This happens without an explicit setup command and suppresses failures. - **Rationale:** The automatic global postinstall mutates a shared AI-agent skill control surface and can recursively remove existing matching content before replacing it. This is concrete install-hook abuse despite the lack of automatic network activity. - **Files touched:** package.json, scripts/postinstall.mjs, skills/zmyt-crm, ~/.agents/skills/zmyt-crm ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs a postinstall script., The script activates for global lifecycle installs and targets the shared AI-agent skills directory., It recursively deletes an existing matching skill entry, then replaces it with a package-controlled symlink., The install-time mutation is silent and does not require a user command. - **Evidence against:** The installer limits entries to names beginning with zmyt-., The postinstall script contains no network request or credential collection. ## Affected versions and remediation This report applies to zmyt-cli@0.2.8. - Avoid installing zmyt-cli@0.2.8. 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.
