Banking Trojan DoubleTrouble propagates through Discord - stay vigilant
DoubleTrouble Android Banking Trojan Now Distributed Through Discord
The DoubleTrouble Android malware, known for its stealthy capabilities, is currently being distributed via Discord by hosting malicious APK files on Discord channels. This represents a shift from its earlier distribution through phishing sites posing as European banks [1][2][3][4].
The malware, upon installation, deploys as an extension or add-on. It poses as a European bank, so users are warned to beware. To avoid falling victim, it's recommended to download apps only from official repositories.
DoubleTrouble's capabilities have evolved, making it a highly dangerous and evolving mobile banking Trojan. It uses Android’s Accessibility Services to silently perform malicious actions, advanced keylogging that captures every keystroke in real time, and screen recording using Android’s MediaProjection and VirtualDisplay APIs to capture sensitive information such as usernames, passwords, and one-time passwords (OTPs) [1][2][3][4].
The malware also employs fake UI overlays, including lock screen mimics, to steal lock screen credentials like PINs, patterns, and passwords. These overlays also appear as system messages to block legitimate banking/security apps. To hide in plain sight, the malware uses the Google Play icon [1][2][3][4].
DoubleTrouble employs obfuscation techniques that disguise method names using random two-word names, complicating reverse engineering. It also uses dynamic payload installation by hiding malicious code in the app’s resources/raw directory. To phish sensitive data stealthily, it mimics trusted apps with tailored HTML overlays [1][2][3][4].
To prevent user interference, the malware blocks legitimate apps with fake "system maintenance" messages. Kern Smith, VP of Solutions Engineering at Zimperium, stated that attackers are shifting to mobile-first strategies and using dynamic delivery methods like Discord to evade traditional defenses. He warned that DoubleTrouble is a stark reminder that mobile threats are growing more evasive and dangerous, targeting banking credentials and cryptocurrency wallets [1][2][4].
Researchers have warned of a "disturbing trend" of social media platforms being used as delivery channels for malware. To defend against such attacks, it is recommended to keep the device protected with Play Protect and Android security solutions [1][2][3][4].
