A newly identified Android banking trojan named Rokarolla has been discovered, distributed through malicious websites masquerading as popular applications like TikTok or Google Chrome. The malware targets 217 distinct cryptocurrency and banking applications using 137 sophisticated commands for device control. Capabilities include harvesting lock screen credentials, exfiltrating contact lists and SMS data, deploying keyloggers, blocking calls, creating fraudulent screen overlays, and disabling Google Play Protect. The infection begins with a dropper impersonating Google Play Protect that installs a secondary payload. Rokarolla communicates with C2 infrastructure via HTTPS, uses overlays to steal banking credentials and device unlock patterns, silently monitors WhatsApp contacts, hijacks SMS and calls, manipulates clipboard content for cryptocurrency theft, and employs snapshot-based screen surveillance. It maintains persistence by hiding its icon, muting device audio, and keeping screens active indefinitely.
Zanubis is an evolving Android banking Trojan that emerged in 2022, targeting financial institutions in Peru before expanding to virtual cards and crypto wallets. It impersonates legitimate apps to trick users into granting accessibility permissions, enabling extensive data theft and device control. The malware has undergone significant development, incorporating features like SMS hijacking, screen recording, and device credential stealing. Recent versions show improved obfuscation, encryption, and silent installation techniques. The threat actors, likely based in Peru, continue to refine the malware's capabilities and targeting strategy, focusing on high-value financial targets in the region.
