What is MAL-2026-6124?
MAL-2026-6124 is a malicious package in @onum-releases/ixel, published on 18 Jun 2026.
Official description
On import, index.js reads os.hostname() and issues an HTTPS GET to
ixel.<hostname>.200majoeu01dk02xnjdajro1isojc90y.oastify.com/ixel (oastify.com is Burp Suite's Collaborator out-of-band interaction domain). The hostname is embedded as a DNS subdomain label, so the DNS resolution alone leaks the installer's hostname to an attacker-controlled nameserver regardless of whether the HTTP request succeeds. Any developer machine or CI runner that require()s this package — directly or transitively — sends a host identifier to the operator of the configured Collaborator instance. The package.json description ("Security PoC placeholder - benign, no runtime payload") contradicts the shipped code, and the @onum-releases scope appears designed to resemble a legitimate vendor releases namespace.What should I do about MAL-2026-6124?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
