Their postinstall script runs `node postinstall.js` on npm install, which POSTs the hostname, username, platform, working directory and the names of all environment variables to `https://www.hinny.shop/api`. They were published by the npm account kill_shs, which also published @zmtcdn/components with the same script.\n\n---\n_-= Per source details.

The package name uses a vendor-style scope (`@zmtcdn/ui`) and an implausibly high version (9999.0.7) consistent with a dependency-confusion lure, and the fetch destination is unrelated to any declared publisher. No user opt-in, no documentation of the beacon, and no legitimate functional purpose for sending this data off-host at install time.\n","state":0,"publishedAt":"2026-10-28T07:27:15+00:00","modifiedAt":"2026-10-29T14:30:31.3761179+00:00","affected":[{"ecosystem":"npm","name":"@zmtcdn/ui","ranges":[],"versions":["9999.0.0","9999.0.7"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@zmtcdn/ui","https://www.npmjs.com/package/@zmtcdn/ui/v/9999.0.0","https://www.npmjs.com/package/@zmtcdn/ui/v/9999.0.7"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18373","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18373","identifiers":["MAL-2026-18373"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
