An unofficial version of the popular WhatsApp messaging app called YoWhatsApp has been observed deploying an Android trojan known as Triada.
The goal of the malware is to steal the keys that “allow the use of a WhatsApp account without the app,” Kaspersky said in a new report. “If the keys are stolen, a user of a malicious WhatsApp mod can lose control over their account.”
