What is MAL-2026-6127?
MAL-2026-6127 is a malicious package in @onum-releases/utils, published on 18 Jun 2026.
Official description
On require('@onum-releases/utils'), index.js reads os.hostname() and issues an HTTP GET to 'utils.<hostname>.200majoeu01dk02xnjdajro1isojc90y.oastify.com', leaking the installer's hostname via DNS and HTTP to an out-of-band collaborator endpoint controlled by the package publisher. The beacon fires unconditionally on module load, so any consumer that imports the package exposes its host identifier to the attacker-controlled collaborator. The package.json description claims 'Security PoC placeholder - benign, no runtime payload', directly contradicting the shipped code. The scope '@onum-releases' impersonates the Onum vendor namespace, consistent with a dependency-confusion lure aimed at that organization's developers.
What should I do about MAL-2026-6127?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
