AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook performs active, automatic credential and host data exfiltration to a package-unrelated fixed endpoint over HTTP and DNS. This is concrete malicious install-time behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-08T16:17:56.503Z - **Finished:** 2026-10-08T16:18:16.147Z - **Download time:** 1018 ms - **Static scan time:** 17 ms - **AI review time:** 18609 ms - **Total time:** 19644 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 collects host identity and sensitive environment values, then exfiltrates them over HTTP and DNS. - **Trigger:** Package installation invokes the postinstall lifecycle script. - **Impact:** Installation can disclose host identity, CI metadata, and available cloud or service credentials to an external endpoint. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:18:16.147Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script serializes host details and selected environment values, posts them to oob.s4yhii.com, and encodes host and username data into DNS queries to that domain. - **Attack narrative:** On installation, the postinstall hook gathers system details and selected environment values, including cloud and CI credentials. It sends the resulting data in an HTTP POST to a fixed external host and encodes host and username information into DNS queries. The hook suppresses errors, so failed delivery does not interrupt installation. - **Rationale:** The postinstall hook performs active, automatic credential and host data exfiltration to a package-unrelated fixed endpoint over HTTP and DNS. This is concrete malicious install-time behavior. - **Files touched:** postinstall.js - **Network endpoints:** oob.s4yhii.com:9999, \*.h.dc.oob.s4yhii.com, \*.u.dc.oob.s4yhii.com, \*.m.dc.oob.s4yhii.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The automatic postinstall hook runs the data-collection script and suppresses its errors., The hook collects CI and cloud credential environment variables., It posts serialized host and environment data to a fixed external host., It sends host and username data in DNS query names. ## Affected versions and remediation This report applies to @galicia-toolkit/tag-manager@999.0.6. - Avoid installing @galicia-toolkit/tag-manager@999.0.6. 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.
