The overridden command collects the installer's hostname, current working directory, and OS username, URL-encodes them, and sends them via an HTTP GET request to a hardcoded Interactsh out-of-band callback subdomain at fpvbsifkklbmklusmxby2405wa7x7x5bf.oast.fun. This fires on default install without user interaction and leaks installer host identifiers to an attacker-controlled OOB server, consistent with a dependency-confusion reconnaissance beacon.\n\n## Source: kam193 (e41b6a5ae4af745c6bc5b2514fa7202d95242ef71a60a57f130524ccfddc99da)\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.
