Malicious code in vercel-runtime-python (PyPI)

Type: advisorySource: OSV1 source record

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (f59b48451cf996ea42b291d60ed56205aeb9803222d156f7880fd6b92032b1c6) The package presents itself as a Vercel Python runtime helper but ships no runtime functionality. 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. ## Source: kam193 (5bd13c006fe4fbaf8bb81d068f6e3c822ea1e664b24d0045370aead862ccd06f) Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose. --- Category: 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.
