A new strain of Android malware called RatOn was identified on July 5, 2025, targeting banking applications and cryptocurrency wallets, particularly in the Czech Republic. It integrates near-field communication (NFC) relay attacks with automated transfer system (ATS) capabilities, allowing attackers to hijack devices and execute unauthorized transactions. RatOn builds on tactics from previous malware like PhantomCard and employs overlay attacks to capture user credentials. It gains root-level access through vulnerabilities such as KernelSU, enabling call hijacking to bypass two-factor authentication. RatOn specifically targets local banking applications and cryptocurrency wallets, scanning for wallet apps and extracting private keys. Defending against RatOn involves enabling app sideloading restrictions, using reputable antivirus software, and monitoring NFC settings, while banks are enhancing anomaly detection systems. The emergence of RatOn raises concerns about mobile security globally, with calls for stricter app store vetting and improved NFC protocols. Experts predict that future malware will increasingly use AI-driven adaptations, complicating detection efforts.
