setup.py overrides the install command to collect the installer's hostname and resolved IP address via socket.gethostname()/gethostbyname() and POST them as JSON to a hardcoded webhook.site endpoint (https://webhook.site/f79bb373-481e-4116-b3d1-35005970b62f) before completing installation. The beacon fires automatically during `pip install` of the sdist. The package's own metadata describes it as a POC beacon; no legitimate functionality accompanies the network callout.

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.
