AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The manifest activates the code automatically, and the source shows identifying host data sent to a fixed external collector through DNS. This is an installation beacon and supports blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-27T12:46:51.345Z - **Finished:** 2026-10-27T12:47:12.150Z - **Download time:** 772 ms - **Static scan time:** 1073 ms - **AI review time:** 18959 ms - **Total time:** 20805 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 automatic preinstall hook discloses the local username and hostname through a DNS lookup to a fixed external OAST domain. - **Trigger:** Installing the package when its preinstall hook runs. - **Impact:** The external domain can receive identifying information about the installing machine and observe the installer's DNS egress. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-27T12:47:12.150Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** index.js builds a DNS name containing the username and hostname, then resolves it. - **Attack narrative:** During package installation, the preinstall hook runs index.js. That code reads the local username and hostname, embeds both in a DNS query to a fixed OAST domain, and performs the lookup without a consent guard. - **Rationale:** The manifest activates the code automatically, and the source shows identifying host data sent to a fixed external collector through DNS. This is an installation beacon and supports blocking publication. - **Files touched:** package.json, index.js - **Network endpoints:** dbg6vplohjpkmtolbi6g18ekofkxjzm4s.oast.fun ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs index.js automatically during preinstall., index.js collects the local username and hostname and embeds them in a DNS name under a fixed OAST domain., The preinstall code resolves that name, sending the identifying values to the external domain. ## Affected versions and remediation This report applies to @azure-growth/signup-ux-components@1.2.2. - Avoid installing @azure-growth/signup-ux-components@1.2.2. 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.
