On npm install the script reads os.hostname() and issues an HTTPS GET to the hardcoded endpoint https://eo8f3m3ho26a0nm.m.pipedream.net/, sending the installer's hostname and the package name as query parameters to an author-controlled pipedream.net webhook collector. The package has no other functionality: package.json carries an empty description, a placeholder ISC license, a name resembling a token, and version 99.99.99 — the canonical shape used to probe whether a private/internal package name resolves against the public npm registry (dependency confusion). The exfiltrated hostname discloses internal build-host or developer-machine identifiers to the beacon operator.\n","state":0,"publishedAt":"2026-09-21T03:32:25+00:00","modifiedAt":"2026-09-21T04:00:05.8233984+00:00","affected":[{"ecosystem":"npm","name":"keroeltopkkk","ranges":[],"versions":["99.99.99"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/keroeltopkkk/v/99.99.99"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16336","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16336","identifiers":["MAL-2026-16336"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
