Sturnus: New Android Banking Trojan Targets WhatsApp, Telegram, Signal
The Android trojan Sturnus targets secure messaging apps like WhatsApp, Telegram, and Signal. It can steal banking credentials, remotely control devices, and bypass encrypted messaging by capturing on-screen content. The malware is still under development but is already targeting financial institutions in certain regions, indicating preparation for a broader campaign. Sturnus uses HTML overlays and accessibility-based keylogging to steal data and monitor user actions in real-time. It also employs screen mirroring and a fallback system for screen capture, ensuring full remote control of infected devices. The malware's sophisticated tactics include device administrator abuse and comprehensive environmental monitoring, making it a significant threat to financial security and privacy.
