AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package's dependency declaration activates a preinstall hook that sends identifying installer and environment data to a collector without a consent guard. This supports blocking as an installation beacon and data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-16T11:13:19.257Z - **Finished:** 2026-10-16T11:13:54.159Z - **Download time:** 770 ms - **Static scan time:** 5 ms - **AI review time:** 34126 ms - **Total time:** 34902 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 this package automatically installs a hosted dependency whose preinstall hook discloses identifying machine and user details. - **Trigger:** npm installs the declared dependency during package installation. - **Impact:** The collector receives identifying details about the installer and its environment without an evident consent guard. - **Evidence paths:** package.json, .lpm-dependency-evidence-8cc63208-59d8-4a37-b422-54369f2e0759/0/npm-linux/package.json, .lpm-dependency-evidence-8cc63208-59d8-4a37-b422-54369f2e0759/0/npm-darwin/package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-16T11:13:54.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The dependency's preinstall command sends the current username, hostname, and working directory in an HTTP POST to artifacts.creditslib.com/api/pings. - **Attack narrative:** Installing the package pulls in a hosted dependency with an automatic preinstall hook. In both inspected npm platform profiles, the hook sends the installer's username, hostname, and current working directory to a collector endpoint. This is an installation-time disclosure of identifying data. - **Rationale:** The package's dependency declaration activates a preinstall hook that sends identifying installer and environment data to a collector without a consent guard. This supports blocking as an installation beacon and 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 package installs daemon-thread-lookup-buffer from a hosted URL, activating that dependency's install lifecycle., The Linux and Darwin dependency manifests each define a preinstall command that POSTs the installer username, hostname, and working directory to artifacts.creditslib.com/api/pings. ## Affected versions and remediation This report applies to @flexmr/utils@2.0.12. - Avoid installing @flexmr/utils@2.0.12. 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.
