Description

setup.py overrides the egg_info command to execute automatically during pip install. The overridden command collects the installer's hostname, current working directory, and OS username, URL-encodes them, and sends them via an HTTP GET request to a hardcoded Interactsh out-of-band callback subdomain at fpvbsifkklbmklusmxby2405wa7x7x5bf.oast.fun. This fires on default install without user interaction and leaks installer host identifiers to an attacker-controlled OOB server, consistent with a dependency-confusion reconnaissance beacon.

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.
