BTMOB Platform Turns Android Banking Trojan into Customizable Fraud Campaign Constructor

Researchers at QuimeraX have uncovered BTMOB, a platform that evolved from a banking trojan into a full-featured builder for fraudulent Android campaigns. The service allows clients without development skills to select an app name, icon, command-and-control server, permissions, and social-engineering lure, after which the system automatically compiles a ready-to-use APK. The package includes an Android payload, dropper, VB.NET control panel, PHP and MySQL backend, and build tools that enable rapid production of localized copies of streaming services, banking protection modules, parcel trackers, and social networks. One BTMOB 2.5 variant was distributed via a phishing site mimicking the Turkish iNat TV service, while Brazilian operators created fake Google Play pages impersonating Nubank, TikTok, and the government portal Gov.BR. After installation, the trojan requests accessibility permissions and, once granted, grants operators near-complete device control including screen viewing, keystroke capture, audio recording, and real-time WebSocket interaction that lets attackers perform actions directly on the victim’s device. Analysts link BTMOB to the SpySolr family and earlier commercial RATs CypherRAT and CraxsRAT, which had already attracted more than 100 licensees.
