identityauthorizationserv@21.0.0

identityauthorizationserv@28.0.0 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. ## Source: ghsa-malware (ef1d43e872519f6b1865d149c6f202e9079165bc28c12645e8154155d61e7455) Any computer that has this package installed or running should be considered fully compromised.
