## Overview

_-= 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.

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.


Campaign: GENERIC-standard-pypi-install-pentest


Reasons (based on the campaign):


 - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.


 - The package overrides the install command in setup.py to execute malicious code during installation.


## Affected packages

- `vercel-runtime-python`

## Remediation

Refer to the advisory for the patched release.
