Maverick: a new banking trojan abusing WhatsApp in a massive scale distribution

A new banking Trojan named Maverick has emerged, targeting Brazilian users through a massive WhatsApp distribution campaign. The infection chain begins with a malicious LNK file sent via WhatsApp, leading to a complex, fileless infection process. Maverick uses the WPPConnect project to automate message sending from hijacked accounts, spreading the malware further. The Trojan monitors 26 Brazilian bank websites, 6 cryptocurrency exchanges, and 1 payment platform, aiming to capture banking credentials. It employs advanced evasion techniques, including AI-assisted code development, and shares similarities with the Coyote banking Trojan. The campaign's impact is significant due to its worm-like nature and exploitation of a popular messaging platform.
