Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The lifecycle hook activates an automatic DNS disclosure of host-identifying data to an unrelated out-of-band recipient. This is concrete install-time collection and transmission, 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:** 2026-10-19T16:27:52.178Z - **Finished:** 2026-10-19T16:31:31.486Z - **Download time:** 756 ms - **Static scan time:** 176 ms - **AI review time:** 218376 ms - **Total time:** 219308 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 lifecycle script runs code that sends host-identifying data through DNS to an out-of-band domain. No consent guard is present in the inspected path. - **Trigger:** The package prepare lifecycle script runs. - **Impact:** The DNS request discloses installation host metadata to an unrelated recipient. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T16:31:31.486Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint resolves a fixed hostname, then makes another DNS lookup whose subdomain contains the machine hostname and the first lookup's result or error code. - **Attack narrative:** The prepare hook starts the entrypoint. It performs a DNS lookup and then sends the host name and lookup result in a second DNS query to an out-of-band domain, without an apparent user-consent check. - **Rationale:** The lifecycle hook activates an automatic DNS disclosure of host-identifying data to an unrelated out-of-band recipient. This is concrete install-time collection and transmission, so the package should be blocked. - **Files touched:** index.js - **Network endpoints:** ssrf-target.iad.github.net, npmint19u4--768.oob.awss.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs index.js from an automatic prepare lifecycle script., index.js queries DNS with the machine hostname and a derived lookup result encoded under an out-of-band domain, without a consent check. ## Affected versions and remediation This report applies to @an1mshnpmb9c84920/pipe-dns-m19t2@1.0.1. - Avoid installing @an1mshnpmb9c84920/pipe-dns-m19t2@1.0.1. 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.
