AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The declared dependency’s Linux and Darwin preinstall hooks automatically disclose installer and environment identifiers to a remote collector. This supports blocking as install-hook abuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-16T10:46:59.130Z - **Finished:** 2026-10-16T10:47:32.800Z - **Download time:** 259 ms - **Static scan time:** 4 ms - **AI review time:** 33406 ms - **Total time:** 33670 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 package brings in a dependency with an automatic preinstall disclosure on Linux and Darwin. - **Trigger:** An npm installation that installs the declared dependency and runs its preinstall hook. - **Impact:** The endpoint receives identifying information about the installer and installation environment. - **Evidence paths:** package.json, .lpm-dependency-evidence-4566f94d-4c24-4668-87b9-d7d2883ab0d7/0/npm-linux/package.json, .lpm-dependency-evidence-4566f94d-4c24-4668-87b9-d7d2883ab0d7/0/npm-darwin/package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-16T10:47:32.800Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook sends the installer’s username, hostname, and current working directory to a remote endpoint without an indicated consent guard. - **Attack narrative:** The package declares a dependency hosted at an external artifact URL. The prepared Linux and Darwin dependency manifests both define a preinstall command that posts the installer’s username, hostname, and working directory to an endpoint on that host. This is automatic installation-time disclosure with no consent guard shown in the inspected source. - **Rationale:** The declared dependency’s Linux and Darwin preinstall hooks automatically disclose installer and environment identifiers to a remote collector. This supports blocking as install-hook abuse. - **Network endpoints:** https://artifacts.creditslib.com/api/pings ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares a dependency fetched from an external artifact host, creating an install path to that dependency., The Linux dependency manifest runs a preinstall command that sends the current user, hostname, and working directory to a remote endpoint., The Darwin dependency manifest contains the same identifying-data transfer in its preinstall command. ## Affected versions and remediation This report applies to @flexmr/utils@1.0.0. - Avoid installing @flexmr/utils@1.0.0. 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.
