On pip install (and even pip download), the package's setup.py overrides the install and egg_info commands to execute a RunCommand() routine that serializes every entry in os.environ into a key=value query string and captures the output of ps -elf. The combined payload is then POSTed via curl over plaintext HTTP to http://gjampdwmdjmppwedtkpbbdkq05f6iiz6r.oast.fun, a unique subdomain on the public interactsh out-of-band testing service. Any CI/build secrets present in the environment at install time (AWS_*, GITHUB_TOKEN, NPM_TOKEN, CI provider tokens, etc.) leak to the attacker-controlled OAST listener, along with a snapshot of running processes on the host.

During installation, the package exfiltrates env variables
