That code collects `os.userInfo().username`, `os.hostname()`, and `process.cwd()` and issues a DNS `resolve4` for a label chain of the form `<pkg>.<user>.<host>.<cwd>.<ts>.oob.algamil7x.xyz`, exfiltrating installer identity and working-directory information over DNS to an attacker-controlled domain. The destination host and the `os`/`dns`/`process` module names are obfuscated in `lib/c5df9a.js` and `lib/b4ce8f.js` using char-code byte arrays (`String.fromCharCode`) and loaded via `module.constructor._load` instead of plain `require`, concealing both the APIs and the C2 destination. The obfuscation and DNS-label-encoded channel are inconsistent with the package's presentation as a shared web assets helper.\n","state":0,"publishedAt":"2026-09-18T14:06:59+00:00","modifiedAt":"2026-09-18T14:30:07.102573+00:00","affected":[{"ecosystem":"npm","name":"@shared-web/assets","ranges":[],"versions":["9.9.10"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@shared-web/assets/v/9.9.10"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16283","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16283","identifiers":["MAL-2026-16283"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
