AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package has no delivered runtime implementation but performs an unconsented external hostname beacon during \`postinstall\`. This is concrete install-time data exfiltration and warrants blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-14T13:46:33.766Z - **Finished:** 2026-07-14T13:47:19.990Z - **Download time:** 506 ms - **Static scan time:** 21 ms - **AI review time:** 45697 ms - **Total time:** 46224 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:** Install-time code contacts an external callback service and includes the local hostname in the request. This is a concrete telemetry/exfiltration action with no package functionality. - **Trigger:** npm package installation - **Impact:** Exposes install occurrence and host identity to a third party. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-07-14T13:47:19.990Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall HTTPS hostname beacon - **Attack narrative:** Installing the package invokes \`postinstall.js\`. It uses \`https.request\` to beacon to an OASTify-controlled host, embedding the local machine hostname in the request path, while suppressing request errors. The declared \`index.js\` entrypoint is absent and the package ships only the postinstall script, so the install-time callback is its only delivered behavior. - **Rationale:** The package has no delivered runtime implementation but performs an unconsented external hostname beacon during \`postinstall\`. This is concrete install-time data exfiltration and warrants blocking. - **Files touched:** package.json, postinstall.js - **Network endpoints:** https://jm93mcf6lwbl1ltezpqohn8t0k6bu4it.oastify.com/poc?evt=install&pkg=home-mp-commons&host={hostname} ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`package.json\` runs \`node postinstall.js\` automatically on install., \`postinstall.js\` sends an HTTPS GET request during install., The request transmits the installing machine hostname to an external OAST host., Request errors are silently ignored, reducing visible failure signals. - **Evidence against:** No credential, token, or file-content harvesting was found in inspected sources. ## Affected versions and remediation This report applies to home-mp-commons@999.0.1. - Avoid installing home-mp-commons@999.0.1. 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.
