A newly discovered piece of Android malware is targeting the users of close to 300 financial applications across the United States and Europe, Cybereason Nocturnus security researchers warn.
Dubbed EventBot, the threat appears to be newly developed, as its code differs significantly from that of other Android malware out there. Furthermore, the researchers believe this banking Trojan and infostealer is under active development and rapidly evolving.
The Trojan was designed to abuse the Android accessibility features to steal user and device information, and data from various applications, including targeted financial software and SMS messages.
EventBot, Cybereason Nocturnus points out, can potentially steal key business data, given that mobile devices tend to store a lot of business data in addition to personal data, especially within organizations that have a bring-your-own-device policy in place.

The Trojan queries a list of installed apps and system information and sends all the data to its command and control (C&C) server in an encrypted form. It can also parse SMS messages, which allows it to bypass two-factor authentication protections.
A function called parseCommand allows the threat to ..
