AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The declared dependency has an automatic preinstall beacon that discloses installer and environment identifiers to a publisher-selected endpoint. This supports blocking as installation-time data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-16T11:12:49.582Z - **Finished:** 2026-10-16T11:13:19.548Z - **Download time:** 1287 ms - **Static scan time:** 12 ms - **AI review time:** 28666 ms - **Total time:** 29966 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:** Installing the declared remote dependency triggers disclosure of installer and environment identifiers to its publisher endpoint. This is an automatic installation beacon with no consent guard shown. - **Trigger:** Installing @flexmr/utils and running the dependency’s preinstall hook. - **Impact:** The publisher receives identifying information about the installer and installation environment. - **Evidence paths:** package.json, .lpm-dependency-evidence-bb3573a3-61e0-403d-92a1-e504181d2441/0/npm-linux/package.json, .lpm-dependency-evidence-bb3573a3-61e0-403d-92a1-e504181d2441/0/npm-darwin/package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-16T11:13:19.548Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook sends an HTTP POST containing the username, hostname, working directory, and a package-linked event identifier. - **Attack narrative:** The root package depends on a remotely hosted package whose npm Linux and Darwin snapshots define a preinstall hook. That hook automatically posts the installer’s username, hostname, and working directory to the publisher’s endpoint. The scanner-profile snapshot lacks the hook, but that variation does not clear the install behavior present in both npm-profile snapshots. - **Rationale:** The declared dependency has an automatic preinstall beacon that discloses installer and environment identifiers to a publisher-selected endpoint. This supports blocking as installation-time data exfiltration. - **Network endpoints:** https://artifacts.creditslib.com/api/pings ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The root manifest declares the remote dependency whose install hook runs during installation., The npm Linux snapshot’s preinstall posts the username, hostname, and working directory to the publisher endpoint., The npm Darwin snapshot contains the same install-time disclosure with a different event identifier. ## Affected versions and remediation This report applies to @flexmr/utils@10.0.12. - Avoid installing @flexmr/utils@10.0.12. 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.
