AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source confirms an automatic installation beacon that discloses identifying host and project metadata to a hardcoded external recipient without installer consent. This meets the installation beacon policy for blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-26T07:25:46.891Z - **Finished:** 2026-10-26T07:29:30.231Z - **Download time:** 775 ms - **Static scan time:** 31 ms - **AI review time:** 222533 ms - **Total time:** 223340 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 discloses machine and project identifiers to a hardcoded external endpoint during installation. Importing its main entrypoint also triggers the beacon. - **Trigger:** Package installation runs the postinstall hook; importing index.js is a second trigger. - **Impact:** The recipient can associate an installation with its host and local paths without installer consent. - **Evidence paths:** package.json, beacon.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-26T07:29:30.231Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** beacon.cjs builds a payload containing the hostname, install path, and working directory, then sends it by HTTP POST to 185.158.107.175. - **Attack narrative:** During postinstall, the package sends host and local path identifiers to a hardcoded external endpoint without an installer consent guard. The main entrypoint independently triggers the same beacon when imported. - **Rationale:** Source confirms an automatic installation beacon that discloses identifying host and project metadata to a hardcoded external recipient without installer consent. This meets the installation beacon policy for blocking. - **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 package runs beacon.cjs automatically through its postinstall lifecycle hook., The beacon sends an HTTP POST to a hardcoded external IP address., The request payload includes the machine hostname, install path, and working directory., Importing index.js also calls the beacon without a user action. ## Affected versions and remediation This report applies to @greenlake/common-context@3.0.0. - Avoid installing @greenlake/common-context@3.0.0. 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.
