AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically transmits host and project environment metadata to a fixed external endpoint during installation, with an additional import-time trigger. This is concrete exfiltration behavior and warrants blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-09T02:46:04.547Z - **Finished:** 2026-10-09T02:46:22.290Z - **Download time:** 1521 ms - **Static scan time:** 12 ms - **AI review time:** 16210 ms - **Total time:** 17743 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 triggers a beacon that transmits local machine and package metadata to a fixed external endpoint. Importing the package also triggers the beacon. - **Trigger:** Package installation or importing index.js. - **Impact:** The endpoint receives identifying details about the machine and consumer project environment. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T02:46:22.290Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** beacon.cjs builds a JSON payload with host and environment metadata and sends it in an HTTP POST. - **Attack narrative:** The postinstall hook launches beacon.cjs, which posts package and host metadata to a fixed external HTTP endpoint. The package entrypoint also fires the beacon when imported. This is active, automatic host metadata exfiltration. - **Rationale:** The package automatically transmits host and project environment metadata to a fixed external endpoint during installation, with an additional import-time trigger. This is concrete exfiltration behavior and warrants blocking. - **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:** package.json runs beacon.cjs automatically after installation., beacon.cjs sends package and host metadata to a fixed external HTTP endpoint., The payload includes hostname, install path, working directory, and npm user agent., Importing index.js also calls the beacon. ## Affected versions and remediation This report applies to wie888r@2.0.1. - Avoid installing wie888r@2.0.1. 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.
