AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The remote dependency’s automatic preinstall collects identifying system data and sends it to an unrelated OAST host. This verified installation-time disclosure warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-16T09:38:29.375Z - **Finished:** 2026-10-16T09:39:00.681Z - **Download time:** 771 ms - **Static scan time:** 37 ms - **AI review time:** 30497 ms - **Total time:** 31306 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:** Installation of the remote dependency triggers disclosure of machine and user identifiers to an unrelated OAST host. - **Trigger:** Installing brass-common installs its remote dependency, whose preinstall script runs automatically. - **Impact:** The identifiers are exposed to the remote collector during dependency installation. - **Evidence paths:** package.json, .lpm-dependency-evidence-9fa2a133-c458-4a57-bd34-509e4c5dabb2/0/package.json, .lpm-dependency-evidence-9fa2a133-c458-4a57-bd34-509e4c5dabb2/0/test.js, .lpm-dependency-evidence-9fa2a133-c458-4a57-bd34-509e4c5dabb2/0/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T09:39:00.681Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script encodes the username, hostname, and home directory and uses each value in an HTTP request hostname. - **Attack narrative:** Installing the package installs a remote tarball dependency. Its preinstall hook runs a script that encodes the system username, hostname, and home directory, then sends requests to an OAST host with each value in the hostname. The dependency issues the HTTP request, so this is an active installation-time disclosure. - **Rationale:** The remote dependency’s automatic preinstall collects identifying system data and sends it to an unrelated OAST host. This verified installation-time disclosure warrants blocking publication. - **Files touched:** package.json, .lpm-dependency-evidence-9fa2a133-c458-4a57-bd34-509e4c5dabb2/0/package.json, .lpm-dependency-evidence-9fa2a133-c458-4a57-bd34-509e4c5dabb2/0/test.js, .lpm-dependency-evidence-9fa2a133-c458-4a57-bd34-509e4c5dabb2/0/index.js - **Network endpoints:** brass-common.fn6vi3beh5nm3yb5n651m03960cx0noc.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package depends on a remote tarball whose manifest runs a preinstall script., That script encodes the machine username, hostname, and home directory, then sends requests using those values to an OAST host., The dependency performs an HTTP request to the constructed destination, making the identifying data disclosure active during installation. ## Affected versions and remediation This report applies to brass-common@99.9.1. - Avoid installing brass-common@99.9.1. 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.
