Package contains code to silently execute a RAT-like agent, allowing the attacker to access the file system and execute arbitrary code.

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

Campaign: 2026-05-venv-utils

Reasons (based on the campaign):

  • rat

  • typosquatting

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

  • obfuscation
