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:** 84.0% - **Started:** 2026-10-15T06:44:23.398Z - **Finished:** 2026-10-15T06:45:19.172Z - **Download time:** 519 ms - **Static scan time:** 36 ms - **AI review time:** 55218 ms - **Total time:** 55774 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 package routes its package-manager registry traffic through a fixed host and uses a native engine downloaded from that host. The engine’s implementation is not available in the inspected source, leaving its behavior unresolved. - **Trigger:** Installation runs the postinstall downloader; a later invocation of pxnpm or pxnpx prepares network settings and launches the native engine. - **Impact:** The fixed host receives package-manager network requests and supplies the executable used for package operations; source inspection cannot establish what the opaque engine does with those requests. - **Evidence paths:** package.json, dist/launcher.cjs, dist/download.cjs, dist/native-manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-15T06:45:19.172Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher overrides the registry and proxy configuration, while the downloader fetches and installs a manifest-pinned native executable. - **Rationale:** Source confirms forced routing through a package-specific registry and proxy, plus installation and execution of a native engine whose implementation is unavailable for review. Hash checks limit download tampering relative to the included manifest, but do not resolve trust in the host or engine, so this remains a warning-level unresolved risk. - **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/, registry-pxnpm.rdc.nfjbill.ren:20022 ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The package postinstall invokes an installer that downloads the native engine., The launcher pins registry traffic to a package-controlled host and replaces inherited proxy settings with a built-in proxy when run., With fixed network policy, the downloader uses the manifest’s download base; it stores the resulting native executable for later use., The downloaded archive and executable are checked against manifest sizes and SHA-256 hashes before the executable is installed and launched., The native engine receives the package-manager arguments and prepared environment; its implementation is not included in the inspected source. - **Evidence against:** The downloader verifies both archive and executable against hashes in the package’s native manifest before installing the executable. ## Affected versions and remediation This report applies to pxnpm@7.0.1. - Avoid installing pxnpm@7.0.1. 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.
