Summary
Malicious code in flask-auth-system (PyPI)
Details

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

Source: kam193 (debc87eb7af33e5146831c7e1b8ff69ccdebe2c9bbf353216c719b10ebe8431c)

On importing the module, the code attempts to span a reverse shell. In the current version, the remote domain does not exist

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2025-04-flask-auth-sys

Reasons (based on the campaign):

  • dependency-confusion

  • The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.

  • obfuscation
