The beacon fires from two independent paths: setup.py calls the reporter at module top level, so it runs during `pip install` of the sdist, and metricboxlite/__init__.py performs the same collect-and-POST at top level, so any `import metricboxlite` also phones home. Network errors are silently swallowed. The destination is an OAST/out-of-band-callback host that is not first-party to the package or its ecosystem, and the collected fields are installer identity rather than package operational data.\n\n## Source: kam193 (83407b9909ebc137e4d47fbb7fe2672a5920dd22bfd7d86ce8edb536bdd5fcab)\nInstalling the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.\n\n\n---\n\nCategory: 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.\n\n\nCampaign: GENERIC-standard-pypi-install-pentest\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username.
