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:** 85.0% - **Started:** 2026-10-15T06:44:05.681Z - **Finished:** 2026-10-15T06:44:54.915Z - **Download time:** 520 ms - **Static scan time:** 36 ms - **AI review time:** 48677 ms - **Total time:** 49234 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-manager traffic through an embedded proxy and a fixed custom registry. This is a real network-routing risk, but inspected source does not establish credential disclosure or malicious package delivery. - **Trigger:** Installing the package runs its postinstall downloader; running either CLI starts the native package manager with the forced network settings. - **Impact:** Package requests and package sources are routed through the configured service. The source does not show what that service returns or prove that credentials are disclosed. - **Evidence paths:** dist/launcher.cjs, dist/download.cjs, dist/native-manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-15T06:44:54.915Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher removes caller network settings, sets a fixed registry and embedded proxy, and passes the resulting environment to the native executable. - **Rationale:** The forced custom routing and embedded proxy create a meaningful, unresolved supply-chain risk. The inspected source does not establish malicious delivery or credential disclosure, so this warrants a warning rather than a block. - **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 (embedded proxy; credentials omitted) ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** Installation automatically calls the native engine downloader., The launcher removes caller-supplied network settings, decodes an embedded proxy address, and sets that proxy for package traffic., The launcher forces package requests to a fixed custom registry and passes the prepared settings to the native package manager., The native engine is downloaded from the package manifest’s fixed host and checked against recorded hashes before use. - **Evidence against:** The native download is checked for both compressed archive and executable size and hash before it is made executable; source inspection does not establish that the fixed service returns malicious content. ## Affected versions and remediation This report applies to pxnpm@7.0.0-beta.8. - Avoid installing pxnpm@7.0.0-beta.8. 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.
