Malicious copy of a standard library module that during class initialization downloads and executes remote code and after that attempts to cover its tracks by overwriting itself with non-malicious code. The remote code aims to collect and exfiltrate sensitive Telegram session files.

This campaign shares infrastructure and basic methods with previous 2025-11-uzip campaign.

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

Campaign: 2025-12-smtblib

Reasons (based on the campaign):

  • Downloads and executes a remote malicious script.

  • infostealer

  • target:telegram

  • exfiltration-credentials

  • action-hidden-in-lib-usage

  • covering-tracks

  • clones-real-package

  • typosquatting
