LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.0.1 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-10464 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-10464 confirms this npm version as malicious. node-procmetrics-data@1.0.1 ships archive-sender.js which, at install/execution, tars the installer's root filesystem (excluding /proc, /sys, /dev, /tmp, /run) into /tmp/.archive\_\*.tar.gz, splits the archive into 200MB chunks, and publishes each chunk as a new version of \`node-procmetrics-data\` to the public npm registry... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-07-13T18:39:44.423Z - **Finished:** 2026-07-13T18:40:18.772Z - **Download time:** 260 ms - **Static scan time:** 7 ms - **AI review time:** 34082 ms - **Total time:** 34349 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:** A dormant script can archive \`/\` and exfiltrate it by publishing chunks to npm. It is not wired to package installation or the empty default entrypoint. - **Trigger:** Explicit execution or import of \`archive-sender.js\`. - **Impact:** Potential disclosure of accessible host files through public npm releases. - **Evidence paths:** archive-sender.js, package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-13T18:40:18.772Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Filesystem-root archive followed by npm package publication using an embedded token. - **Rationale:** The package contains a concrete host-data exfiltration payload, but source inspection shows it is dormant rather than install- or import-triggered. Treat it as a staged payload carrier and warn rather than block. - **Files touched:** archive-sender.js, package.json, index.js, /tmp/.archive\_\.tar.gz, /tmp/npm-chunk-\/data.bin - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for AI warning decision:** \`archive-sender.js\` archives filesystem root using \`tar\` via \`bash\`., \`archive-sender.js\` splits the archive and republishes chunks with \`npm publish\`., \`archive-sender.js\` decodes an embedded npm token and configures it for npmjs., \`archive-sender.js\` invokes \`archiveAndSend()\` at module load. - **Evidence against:** \`package.json\` has no lifecycle scripts or entrypoint fields., \`index.js\` is empty and does not import \`archive-sender.js\`., The payload is not reachable through normal package install or import. ## Affected versions and remediation This report applies to node-procmetrics-data@1.0.1. - Avoid installing node-procmetrics-data@1.0.1. 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.
