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:** 7.0.2 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-17710 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-2026-17710 confirms this npm version as malicious. pxnpm 7.0.0-beta.6, 7.0.0-beta.8 and 7.0.0 (published 2026-10-06 by user nfjbill) are a 10-file, 16 KB launcher for a native executable that is not contained in the package. The postinstall script (bin/install.cjs) calls ensureNative() in dist/download.cjs, which downloads a 17-21 MB Brotli archive for the current platform from a non-npm host,... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-15T06:44:23.404Z - **Finished:** 2026-10-15T06:45:22.636Z - **Download time:** 513 ms - **Static scan time:** 36 ms - **AI review time:** 58682 ms - **Total time:** 59232 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:** The launcher forces package operations through a publisher-selected registry and proxy, and rejects user network overrides. This creates a concrete risk that dependency requests reach those services, but the inspected source does not establish what data they receive or whether packages are substituted. - **Trigger:** Installing the package invokes its postinstall downloader; running pxnpm invokes the launcher and native executable. - **Impact:** Package requests may disclose dependency and project-related request data to publisher-selected services; the source does not establish credential disclosure or malicious package substitution. - **Evidence paths:** package.json, bin/install.cjs, dist/launcher.cjs, dist/download.cjs, dist/native-manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-15T06:45:22.636Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher sets a fixed registry, decodes and applies a proxy URL, removes inherited network overrides, and passes the resulting environment to the native executable. - **Rationale:** The forced registry and proxy are active package-manager behavior, not merely scanner hints, and callers cannot override them through inherited settings or network flags. The inspected source does not prove credential theft or package substitution, so this is a warning for unresolved dangerous routing capability rather than a confirmed attack. - **Files touched:** package.json, bin/install.cjs, dist/launcher.cjs, dist/download.cjs, dist/native-manifest.json - **Network endpoints:** https://registry-pxnpm.rdc.nfjbill.ren:20021/, https://registry-pxnpm.rdc.nfjbill.ren:20021/\_\_static/srv/downloads/pxnpm ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The package runs a postinstall hook that invokes the native downloader., The launcher forces package operations to use a publisher-selected registry., The launcher decodes a release-staged proxy URL and applies it to HTTP and HTTPS proxy settings., The launcher rejects external network flags and removes inherited network overrides., The native downloader uses the fixed manifest download host., The launcher starts the native executable with the prepared arguments and environment., The downloader checks the native archive and executable against expected sizes and hashes. ## Affected versions and remediation This report applies to pxnpm@7.0.2. - Avoid installing pxnpm@7.0.2. 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.
