MAL-2026-11100 Malicious code in identityauthorizationserv (npm)

[email protected] wires scripts.preinstall to node index.js, so on npm install the package auto-executes code that collects host reconnaissance data (os.hostname(), os.platform(), os.arch(), os.homedir(), and dns.getServers()) and POSTs it to a hardcoded out-of-band callback host at lwl8ethu6t8j3dg96z7zfd7scjib68ux.oastify.com/hit. oastify.com is Burp Collaborator infrastructure used for OOB exfiltration in dependency-confusion probes; the destination is attacker-controlled and unrelated to any legitimate publisher. The package self-describes as a dependency-confusion proof of concept, and the name pattern is consistent with a squat targeting an internal package name.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
