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.

The package's setup.py, executed automatically during pip install, iterates a hardcoded list of installer-side filesystem paths (/flag, /flag.txt, /app/flag, /root/flag, and similar candidates), reads their contents, and transmits them via urllib.request.urlopen as a query-string parameter to the hardcoded endpoint https://webhook.site/f41d2013-dd84-4139-85f8-8e989e0761b8. The webhook.site host is an anonymous request-collector controlled by whoever provisioned that endpoint. The name and version suggest a proof-of-concept exfiltration package, but the shipped code performs real install-time filesystem reads and outbound HTTP exfiltration against any host that runs pip install on this artifact.

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.
