Its only substantive code path is a public function send_info() that gathers hostname, resolved IP, operating system, and machine architecture via get_device_info() and POSTs the result as JSON to the hardcoded URL https://webhook.site/f9bff304-3053-4d54-be05-86537267514a. The destination is not caller-configurable, is not documented, and is not associated with Vercel. Any consumer that invokes the advertised API silently discloses host reconnaissance data to an attacker-controlled webhook.site inbox. The typosquat-shaped name (mimicking an official Vercel component) combined with a module surface consisting solely of host-info collection and outbound POST is consistent with reconnaissance-oriented installer targeting rather than a legitimate runtime library.\n\n## Source: kam193 (5bd13c006fe4fbaf8bb81d068f6e3c822ea1e664b24d0045370aead862ccd06f)\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.
