The package ships no actual functionality — it impersonates the Nagios XI commercial monitoring product (name `nagios-xi`, version `19.5.0` mimicking real Nagios XI versioning) while declaring an anonymous ProtonMail author (`Coding Team <pocbug@protonmail.com>`), a generic `package utility` description, and an empty README. The combination of brand impersonation, placeholder metadata, and an import-time OAST beacon as the package's sole behavior is reconnaissance for a supply-chain attack against developers searching for Nagios XI integrations.

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.
