Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An install hook imports a runtime chain that executes an obfuscated DNS telemetry probe. The probe sends local user, host, and project-directory identifiers in a DNS query. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-26T05:36:38.712Z - **Finished:** 2026-09-26T05:37:36.369Z - **Download time:** 773 ms - **Static scan time:** 48 ms - **AI review time:** 56835 ms - **Total time:** 57657 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 install hook imports a runtime chain that executes an obfuscated DNS telemetry probe. The probe sends local user, host, and project-directory identifiers in a DNS query. - **Trigger:** npm installation runs node index.js. - **Impact:** Installation exposes host and project metadata to nfamh.oob.algamil7x.xyz without a user action. - **Evidence paths:** package.json, index.js, runtime/support/telemetry/index.js, runtime/support/telemetry/probe/impl.js, runtime/support/telemetry/probe/c6e2a9.js, runtime/support/telemetry/probe/d7f3b0.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T05:37:36.369Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time code gathers local identifiers, constructs a subdomain, and calls the DNS resolver. - **Attack narrative:** During npm installation, the package entrypoint imports its runtime and telemetry probe. The probe immediately gathers a local account name, machine host name, and current project-directory basename. Obfuscated code turns those values into a DNS query under an external domain, transmitting the metadata to its operator. - **Rationale:** This is an active, obfuscated install-time metadata exfiltration path. It has no necessary relationship to a global-header component. - **Files touched:** package.json, index.js, runtime/support/telemetry/index.js, runtime/support/telemetry/probe/impl.js, runtime/support/telemetry/probe/c6e2a9.js, runtime/support/telemetry/probe/d7f3b0.js - **Network endpoints:** nfamh.oob.algamil7x.xyz ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The install lifecycle automatically runs the package entrypoint., The entrypoint loads the runtime during installation., The telemetry module loads the probe as part of that runtime import chain., The probe collects the operating-system user name, host name, and current-directory basename., The probe encodes those values into a DNS name and resolves it., Obfuscated helpers load operating-system and DNS modules and decode the external DNS suffix. ## Affected versions and remediation This report applies to @nf-addons/am-global-header@9.9.10. - Avoid installing @nf-addons/am-global-header@9.9.10. 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.
