AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The active CLI path overrides the user's registry and forwards inherited package-manager configuration to the engine, creating an unconsented credential-disclosure path. This supports blocking publication as credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-15T06:44:36.312Z - **Finished:** 2026-10-15T06:45:32.559Z - **Download time:** 512 ms - **Static scan time:** 36 ms - **AI review time:** 55698 ms - **Total time:** 56247 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 CLI routes package-manager operations to a fixed publisher-selected registry and configures an embedded authenticated proxy. Inherited package-manager configuration reaches the native engine, creating a path for registry credentials to be sent to that selected service. - **Trigger:** A user runs a normal pxnpm command that accesses a package registry. - **Impact:** Registry authentication credentials may be disclosed to a recipient selected by the package rather than the user's configured registry. - **Evidence paths:** package.json, bin/pxnpm.cjs, dist/pxnpm.cjs, dist/launcher.cjs, dist/native-manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-15T06:45:32.559Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher forwards inherited package-manager configuration, replaces the registry with its fixed endpoint, configures its built-in proxy, and starts the native engine with that environment. - **Attack narrative:** When a user runs the CLI, pxnpm passes inherited package-manager settings to its native engine while replacing the registry with a fixed publisher-selected endpoint and setting a built-in authenticated proxy. This makes credentials in inherited registry configuration available to a recipient the user did not select. - **Rationale:** The active CLI path overrides the user's registry and forwards inherited package-manager configuration to the engine, creating an unconsented credential-disclosure path. This supports blocking publication as credential exfiltration. - **Files touched:** package.json, bin/pxnpm.cjs, dist/pxnpm.cjs, dist/launcher.cjs, dist/native-manifest.json - **Network endpoints:** https://registry-pxnpm.rdc.nfjbill.ren:20021/, https://registry-pxnpm.rdc.nfjbill.ren:20022 ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package exposes a CLI described as an ARK package manager, and its entrypoint launches the runtime launcher for ordinary commands., The launcher copies inherited package-manager configuration into the native engine's environment, including configuration values that are not registry or proxy settings., Before launching the engine, the launcher forces a publisher-selected registry and a built-in proxy decoded from an embedded value; it also rejects caller attempts to set external registry or proxy flags., The native engine receives the prepared environment, and the configured registry host is also used for native downloads. ## Affected versions and remediation This report applies to pxnpm@7.0.0. - Avoid installing pxnpm@7.0.0. 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.
