Summary
Malicious code in risk-utilities (PyPI)
Details

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

Source: kam193 (e348257ce9a3bae45ebd2659c04fbfea50b94293533efd04ce326900921fd130)

During installation, the package starts obfuscated code that downloads and runs remote executables in specific environments - in older packages - attempts to exfiltrate some basic information using DNS requests and then likely cover tracks by installing a similarly named package from private repository

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

Campaign: 2026-02-urllib-slim

Reasons (based on the campaign):

  • typosquatting

  • Downloads and executes a remote executable.

  • obfuscation

  • dependency-confusion
