The script fires automatically on npm install, confirming installation on the installer's machine and providing a channel to exfiltrate host or environment values via the expanded shell expression. The shipped index.js is an empty stub, so the manifest's postinstall beacon is the package's entire effect. The destination is an anonymous ngrok-free.app tunnel with no relationship to any legitimate publisher, consistent with a dependency-confusion or install-confirmation probe.\n","state":0,"publishedAt":"2026-10-29T14:59:21+00:00","modifiedAt":"2026-10-29T15:30:05.3951173+00:00","affected":[{"ecosystem":"npm","name":"black-spindle-2","ranges":[],"versions":["301.0.0","100.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/black-spindle-2/v/301.0.0","https://www.npmjs.com/package/black-spindle-2/v/100.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18376","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18376","identifiers":["MAL-2026-18376"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
