TikTok and Google: Android Banker Rokarolla Uses Fake Overlays to Steal PINs, Passwords, and Crypto Wallet Data

New Android Banking Trojan "Rokarolla" Targets 217 Financial Apps in Sophisticated Fraud Campaign

A newly discovered Android banking trojan, Rokarolla, is actively draining victim accounts by targeting 217 banking and cryptocurrency applications through a multi-stage attack chain. Named after its primary Command and Control (C2) infrastructure, the malware spreads via malicious phishing websites impersonating legitimate download portals for apps like TikTok and Google Chrome.

Once installed, Rokarolla deploys a deceptive dropper that tricks users into installing a secondary payload disguised as Google Play Protect to bypass security restrictions. The malware then exploits Android’s Accessibility Services, granting it deep control over the device, including the ability to click through prompts, read on-screen content, and maintain persistence without user interaction.

At the heart of its operation, Rokarolla uses fraudulent screen overlays to intercept credentials. When a victim opens a targeted financial app, the trojan dynamically injects a fake HTML-based phishing page over the legitimate interface, capturing login details, PINs, and credit card information. It even mimics the Android lock screen to steal device PINs and swipe patterns, allowing attackers to bypass security measures.

Beyond credential theft, Rokarolla employs a pseudo-VNC mechanism, silently capturing and exfiltrating screenshots with timestamps while abusing the device clipboard to swap cryptocurrency wallet addresses in real time. This tactic ensures attackers intercept transactions before they’re finalized.

Security researchers have identified malicious distribution URLs (e.g., hxxps[://]infocontablidades[.]it[.]com/) and the active C2 domain (beralisvc.info), with Indicators of Compromise (IOCs) available for further analysis. The trojan’s 137 administrative commands enable undetected financial fraud, making it a severe threat to Android users.
