WhatsApp Web malware spreads banking trojan automatically

A new malware campaign is turning WhatsApp Web into a weapon. Security researchers say a banking Trojan linked to Astaroth is now spreading automatically through chat messages, making the attack harder to stop once it starts. 

The campaign is known as Boto Cor-de-Rosa. It shows how cybercriminals keep evolving, especially when they can abuse tools people trust every day. This attack focuses on Windows users and uses WhatsApp Web as both the delivery system and the engine that spreads the infection further.
