AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The manifest activates a postinstall hook that automatically discloses identifying host and user metadata to a fixed external collector. This is an installation beacon and warrants blocking; the source does not show environment variable values being collected. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-28T11:54:39.450Z - **Finished:** 2026-10-28T11:55:05.378Z - **Download time:** 765 ms - **Static scan time:** 9 ms - **AI review time:** 25154 ms - **Total time:** 25928 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:** The install hook automatically sends identifying host and user information to a fixed external webhook. - **Trigger:** Installing the package runs its postinstall script. - **Impact:** An external recipient receives identifying installation and host metadata. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-28T11:55:05.378Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook gathers host, user, working-directory, and environment-key metadata, then POSTs it to webhook.site without a consent check. - **Attack narrative:** On package installation, the postinstall hook collects host and user identifiers, the current directory, and environment variable names. It sends this data to a fixed webhook.site endpoint without an installer consent guard. - **Rationale:** The manifest activates a postinstall hook that automatically discloses identifying host and user metadata to a fixed external collector. This is an installation beacon and warrants blocking; the source does not show environment variable values being collected. - **Files touched:** package.json, postinstall.js - **Network endpoints:** https://webhook.site/f52af355-4783-4acb-9de1-5e44b5963025 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs postinstall.js automatically during installation., postinstall.js collects host name, platform, username, working directory, environment variable names, and time., postinstall.js sends the collected data by POST to a fixed webhook.site URL without a consent guard. - **Evidence against:** The hook collects environment variable names, not their values. ## Affected versions and remediation This report applies to @zmtcdn/components@9999.0.0. - Avoid installing @zmtcdn/components@9999.0.0. 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.
