Zimperium’s zLabs has identified a new Android banking trojan, Rokarolla, that targets 217 banking and cryptocurrency applications and gives attackers broad control over infected devices through 137 remote commands. The malware is distributed via malicious websites impersonating popular apps such as TikTok and Chrome, then installs a secondary dropper disguised as Google Play Protect to obtain Accessibility permissions and deploy the payload. Researchers said Rokarolla steals credentials with fake overlays and phishing pages placed over legitimate financial apps and even the device lock screen, enabling theft of usernames, passwords, PINs, and SMS one-time codes.
Beyond financial theft, Rokarolla supports deep surveillance and device manipulation, including keylogging, screenshot and screen-log capture, contact and notification scraping, WhatsApp data theft, call suppression, sound muting, clipboard hijacking to reroute cryptocurrency transfers, and disabling Google Play Protect scans. Zimperium said the malware also uses multiple fallback command-and-control domains and a Pseudo-VNC capability to maintain resilient access and monitor victims in near real time, underscoring how Android banking trojans are evolving from credential theft into full device takeover that can bypass multi-factor authentication protections.

Zimperium zLabs identified four Android malware families—**RecruitRat, SaferRat, Astrinox, and Massiv**—in active campaigns targeting users of more than **800 banking, cryptocurrency, and social media apps**. The malware is being spread through phishing sites, smishing messages, fake job application and streaming lures, counterfeit app-store pages, and bogus updates that trick victims into installing malicious APKs. Researchers said the campaigns rely heavily on overlay attacks, with fake login screens placed over legitimate apps to steal credentials; **RecruitRat** alone reportedly includes more than **700** fraudulent login pages. Once installed, the trojans abuse Android features including **Accessibility Services**, the **Session Installation API**, **MediaProjection**, overlays, and **WebView** to gain persistence, intercept SMS and one-time passwords, log keystrokes, enumerate apps, steal contacts, freeze screens, stream displays, and remotely control infected devices. The malware also uses anti-analysis techniques such as APK tampering, encrypted strings, reflection, dynamic DEX loading, and environment-aware execution, while command-and-control traffic is sent over HTTPS or WebSockets, with RecruitRat additionally using **RC4** encryption. Researchers warned the activity creates enterprise risk because infected employee devices can enable account takeover, bypass MFA, and expose corporate resources.

Researchers identified **OverlayPhantom**, a previously undocumented Android banking trojan distributed through malicious URLs that impersonate trusted apps including Austria’s **ID Austria** and **TikTok**. The malware uses a two-stage infection chain: a dropper installs a payload disguised as **Google Play Services**, then abuses Android **Accessibility Service** to gain persistent control of the device. Investigators said the campaign has been active since early May 2025 and is aimed at large-scale financial fraud across Western markets. OverlayPhantom targets more than **180 banking, financial, and cryptocurrency applications** across **10 countries**, using embedded HTML overlay phishing pages to steal credentials and payment data. The malware also leverages Android’s **MediaProjection API** for near-real-time JPEG screen streaming and supports more than **30 remote commands**, including gesture simulation, clipboard manipulation, fake notifications, device locking, and PIN or password capture. Its command-and-control infrastructure was tied to `199.217[.]99[.]122`, using non-standard ports `9091`, `9092`, and `9090` for command execution, device reporting, and screen streaming.

A sophisticated Android banking Trojan, identified as Android/BankBot-YNRK, has been discovered targeting users primarily in Indonesia and potentially other Southeast Asian countries. The malware disguises itself as legitimate applications, including news readers and digital ID apps such as "Identitas Kependudukan Digital," to trick users into installation. Once installed, it leverages Android's accessibility features and device administrator privileges to gain extensive control over the device, allowing it to read on-screen content, simulate user actions, and overlay fake login screens on top of real banking and cryptocurrency apps to harvest credentials. The Trojan employs advanced evasion techniques, such as checking for emulators to avoid detection, obfuscating its code, and muting device notifications to operate stealthily. It connects to a remote command-and-control server to exfiltrate sensitive data, including banking credentials and cryptocurrency wallet keys, and can receive further instructions to update itself or erase traces. The malware's primary objective is financial theft, enabling attackers to drain victims' bank accounts and crypto wallets without their knowledge. Security researchers note that the malware's abuse of accessibility permissions is mitigated in Android 14, which requires explicit user approval for such access, but devices running Android 13 and earlier remain vulnerable.
