Details

Source: kam193 (6f61fcbf30122cbf577490fab3968c6b41f95d4d23f6916a7211066bd735ff6e)

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
