AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source confirms unconsented installation-time disclosure of identifying host and project metadata to a fixed external endpoint with no evident functional need. This supports blocking as install hook abuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-26T07:23:32.332Z - **Finished:** 2026-10-26T07:24:15.394Z - **Download time:** 780 ms - **Static scan time:** 13 ms - **AI review time:** 42268 ms - **Total time:** 43062 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:** An automatic install hook reports machine and package-location metadata to a fixed external endpoint. Importing the package entrypoint also triggers the report. - **Trigger:** Package installation or import of index.js. - **Impact:** The endpoint receives the machine hostname, install path, working directory, and npm version. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-26T07:24:15.394Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The beacon constructs a metadata payload and sends it by HTTP POST without an affirmative consent check. - **Attack narrative:** Installing the package automatically runs a beacon that sends machine and package-location metadata to a fixed external endpoint. The package entrypoint triggers the same report when imported. - **Rationale:** Source confirms unconsented installation-time disclosure of identifying host and project metadata to a fixed external endpoint with no evident functional need. This supports blocking as install hook abuse. - **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 during postinstall., The beacon sends a POST to a fixed external HTTP endpoint., The transmitted payload includes the machine hostname, install path, working directory, and npm version., The beacon also fires when the package entrypoint is imported. ## Affected versions and remediation This report applies to @greenlake/session@2.0.0. - Avoid installing @greenlake/session@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.
