AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source confirms an automatic install-time beacon that sends host and project metadata to an unrelated fixed endpoint. This is concrete exfiltration behavior, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-09T06:58:03.370Z - **Finished:** 2026-10-09T06:58:25.178Z - **Download time:** 514 ms - **Static scan time:** 12 ms - **AI review time:** 21281 ms - **Total time:** 21808 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 reports local machine and project metadata to a fixed external endpoint. Installation triggers the report, and importing the package triggers it again. - **Trigger:** npm postinstall or importing index.js - **Impact:** The operator of the endpoint receives identifying host and project-path metadata without an install-time opt-in. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:58:25.178Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** beacon.cjs gathers the hostname, install path, current working directory, and npm user agent, then sends them in an HTTP POST. - **Attack narrative:** During installation, the postinstall hook runs beacon.cjs, which posts the hostname, install path, working directory, and npm user agent to a fixed external IP. Importing the package also invokes the beacon. This is active metadata exfiltration. - **Rationale:** Source confirms an automatic install-time beacon that sends host and project metadata to an unrelated fixed endpoint. This is concrete exfiltration behavior, so the package should be blocked. - **Files touched:** beacon.cjs - **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 runs beacon.cjs automatically., beacon.cjs sends an HTTP POST to a fixed external IP address., The payload includes the machine hostname, install path, working directory, and npm user agent., Importing index.js also triggers the beacon. ## Affected versions and remediation This report applies to testrrrd@1.0.0. - Avoid installing testrrrd@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.
