AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically sends host and CI details to an unrelated external collector during installation. This is concrete install-time data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-29T17:26:31.832Z - **Finished:** 2026-10-29T17:26:50.734Z - **Download time:** 771 ms - **Static scan time:** 10 ms - **AI review time:** 18120 ms - **Total time:** 18902 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 collects host and CI details and sends them to an external collector. - **Trigger:** Package installation runs the postinstall script. - **Impact:** Unsolicited disclosure of local machine and CI environment details. - **Evidence paths:** package.json, index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-29T17:26:50.734Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script gathers hostname, home directory, platform, and CI provider, then POSTs the data to a fixed webhook.site endpoint. - **Attack narrative:** On installation, the postinstall hook runs index.cjs. It collects the machine hostname, home directory, platform, and a CI provider label, then sends those details in a POST request to a fixed webhook.site URL without installer consent. - **Rationale:** The package automatically sends host and CI details to an unrelated external collector during installation. This is concrete install-time data exfiltration. - **Files touched:** package.json, index.cjs - **Network endpoints:** https://webhook.site/d730a68c-27bd-4bb5-b1b9-d57a0a4b17ac/semz ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall script automatically runs index.cjs., index.cjs collects the machine hostname, home directory, platform, and CI provider., index.cjs sends the collected data in a POST request to a fixed webhook.site URL. ## Affected versions and remediation This report applies to @pcb-dp/qa-commons@1.0.0. - Avoid installing @pcb-dp/qa-commons@1.0.0. 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.
