Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose. Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities. Campaign: GENERIC-standard-pypi-install-pentest Reasons (based on the campaign): - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk. - The package overrides the install command in setup.py to execute malicious code during installation. Judge assessment: This is a dependency-confusion proof-of-concept that clearly phones home on import/install, but the package also self-identifies as security research and bug bounty material in both the module docstring and setup metadata. The `setup.py` code collects `socket.gethostname()`, `os.environ` username, current working directory, and pip config paths, then sends them via `urllib.request.urlopen()` and DNS lookup to `abc123.oast.fun` / `webhook.site`, which is consistent with exfiltration behavior. However, the presence of `print("[DEPENDENCY CONFUSION] ... Security research PoC")`, the `https://bugcrowd.com` URL, and the explicit researcher contact strongly indicate a pentest/test package rather than real malware. Because the attacker model is ambiguous and the package appears designed to demonstrate install-time callback behavior, this should be treated as suspicious but likely a false positive for malware submission.
