Summary
Malicious code in @onum-releases/ixel (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (188c65369497c00333fc54291c970071044f3237a255387903a707cfd2711599)

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.
