The destination is an oast.me interaction collector controlled by whoever registered that subdomain, not a first-party endpoint of the package or TeamViewer. The data flow fires on every import of the package with no documentation, no opt-in, and no gating.\n\n## Source: kam193 (6b304890f921805fe9244874cd220f54c2def48cadfe880097124afef1dc4bfc)\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.
