Its postinstall.js runs automatically on npm install and POSTs a host fingerprint (hostname, username, platform, arch, cwd, node version, pid, non-internal IP addresses, uptime, package name) to the hardcoded bare-IP endpoint http://69.48.229.140:8080/b. Its main entry index.js opens a require-time HTTP polling channel to the same host, retrieves JSON commands from /c every 30 seconds (with 10-minute re-beacons), executes them via child_process.exec, and posts stdout/stderr back to /r — providing full remote code execution on the installer's machine. A source comment self-identifies the code as a 'Minimal stealth agent' and 'typosquat'.\n","state":0,"publishedAt":"2026-09-16T06:27:22+00:00","modifiedAt":"2026-09-16T06:45:06.5932846+00:00","affected":[{"ecosystem":"npm","name":"@prime0/alanced-match","ranges":[],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@prime0/alanced-match/v/1.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16204","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16204","identifiers":["MAL-2026-16204"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
