AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall beacon sends host and project metadata to a hard-coded external endpoint, establishing covert data exfiltration. The package's import-time beacon and no-op proxy reinforce that this is not ordinary compatibility-shim behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-09T11:10:57.038Z - **Finished:** 2026-10-09T11:11:21.222Z - **Download time:** 1527 ms - **Static scan time:** 14 ms - **AI review time:** 22643 ms - **Total time:** 24184 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 package automatically reports host and install-directory metadata to an external endpoint during installation. Importing its main entry point also triggers the report. - **Trigger:** Package installation or import of index.js. - **Impact:** The recipient learns identifying host and project directory metadata without an explicit runtime call by the user. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T11:11:21.222Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook runs beacon.cjs, which sends a JSON POST to a hard-coded IP. The payload contains host and package-install context. - **Attack narrative:** Installation invokes the beacon automatically. It sends the machine hostname, installation path, working directory, package identity, and npm version to a fixed external IP. Importing the package also fires the same report; the main export is a proxy that supplies no-op functions. - **Rationale:** The automatic postinstall beacon sends host and project metadata to a hard-coded external endpoint, establishing covert data exfiltration. The package's import-time beacon and no-op proxy reinforce that this is not ordinary compatibility-shim behavior. - **Files touched:** package.json, beacon.cjs, index.js - **Network endpoints:** http://185.158.107.175:8787/\_ah/dc ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook automatically runs beacon.cjs., beacon.cjs sends a POST to a hard-coded external IP address., The payload includes the machine hostname, install path, current directory, and npm version., Importing index.js also calls the beacon, and its proxy returns no-op functions. ## Affected versions and remediation This report applies to @wxwxtest/testrrrdd@1.0.0. - Avoid installing @wxwxtest/testrrrdd@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.
