Source: kam193 (4c3a6759d779c0fe3ffac5559aa5f8915f72cab6bce545e1fe261f3caab47a65)

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.
