If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

PirxcyPackage/__init__.py fetches https://pastebin.com/raw/91tFF63S and passes the response body to exec() on every import. This is a textbook remote-code-execution supply-chain pattern: the payload is mutable, unauthenticated, unsigned, and controlled by a third-party paste owner, so any installer importing this package runs arbitrary attacker-chosen Python. The staging via Pastebin also ensures static review of the wheel cannot observe actual behavior. Installer harm is direct and unambiguous.
