AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The automatically triggered install hook transmits collected host and environment information to an unrelated external endpoint. This is concrete install-time data exfiltration, supporting a malicious verdict and block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-08T15:26:44.348Z - **Finished:** 2026-10-08T15:27:00.266Z - **Download time:** 1016 ms - **Static scan time:** 15 ms - **AI review time:** 14886 ms - **Total time:** 15918 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 install hook gathers host and environment details and transmits them externally over HTTP and DNS. - **Trigger:** Automatic package installation invokes the postinstall script. - **Impact:** Installation exposes local machine, user, and environment metadata to an external recipient. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T15:27:00.266Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script posts serialized host and environment data to oob.s4yhii.com and sends hostname and username encodings in DNS queries to subdomains of that host. - **Attack narrative:** On installation, postinstall.js collects system identity and selected environment values, posts the serialized data to an external host, and issues DNS queries containing encoded hostname and username data. The hook suppresses errors, so these transmissions run without visible failure reporting. - **Rationale:** The automatically triggered install hook transmits collected host and environment information to an unrelated external endpoint. This is concrete install-time data exfiltration, supporting a malicious verdict and block. - **Network endpoints:** oob.s4yhii.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs postinstall.js automatically during installation., postinstall.js collects host, user, network, environment, and CI data, then sends it to an external HTTP endpoint and encodes host and username in DNS queries. ## Affected versions and remediation This report applies to @galicia-toolkit/spa-build-config@999.0.5. - Avoid installing @galicia-toolkit/spa-build-config@999.0.5. 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.
