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-2026-18648 confirms this npm version as malicious. Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-04T21:34:07.500Z - **Finished:** 2026-11-04T21:35:03.867Z - **Download time:** 771 ms - **Static scan time:** 417 ms - **AI review time:** 55178 ms - **Total time:** 56367 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:** Creating NMiner without an address can direct mining proceeds to the maintainer's published donation address. - **Trigger:** A caller constructs NMiner without providing an address; mining begins after the constructor connects and receives a job. - **Impact:** Users who omit the address may spend CPU resources mining shares credited to the maintainer. - **Evidence paths:** index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-04T21:35:03.867Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The miner defaults to a hard-coded pool and XMR address, logs in with that address, then starts its native mining job. - **Rationale:** The package is intentionally a miner and does not mine on import, but constructing it without an address silently sends mining proceeds to the maintainer's donation address. This undisclosed default creates a meaningful risk for callers who omit the wallet parameter, so warn rather than block. - **Network endpoints:** pool.supportxmr.com:3333 ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** NMiner defaults to pool.supportxmr.com:3333 and a hard-coded XMR address., Constructing NMiner triggers a connection automatically unless stealth mode delays it., The same hard-coded XMR address is listed in the README as the maintainer's donation address., The pool login uses the configured address, and mining starts after a job arrives. - **Evidence against:** The package is explicitly described as a RandomX CPU miner, and its quick-start example supplies the user's wallet address., The manifest declares no install, preinstall, or postinstall scripts., The concern is triggered by creating a miner instance; importing the package alone does not start mining. ## Affected versions and remediation This report applies to nminer@3.0.0. - Avoid installing nminer@3.0.0. 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.
