Modern Android banking malware is evolving with architectural enhancements for increased stealth, resilience, and operational flexibility. In early 2026, a new variant of the TrickMo Android banking trojan was identified, actively targeting banking and wallet users in France, Italy, and Austria. This variant has replaced its predecessor in ongoing campaigns and has transitioned its command-and-control traffic to The Open Network (TON). Key features of the new TrickMo variant include: - The primary command-and-control channel now operates over TON, utilizing .adnl endpoints through an embedded local TON proxy. - It employs a runtime-loaded APK (dex.module) with enhanced functionalities, including reconnaissance, SSH tunneling, and SOCKS5 proxying, allowing infected devices to act as network pivots. - TrickMo is classified as Device Take Over (DTO) malware, targeting banking, fintech, wallet, and authenticator applications on Android devices. - Operators gain control over infected devices through accessibility-service permissions, enabling capabilities such as credential phishing, keylogging, screen recording, remote control, and SMS interception. The new variant features a modular architecture with a host APK functioning as a launcher and persistence layer, while offensive capabilities are delivered through the dynamically loaded dex.module. Significant enhancements include network reconnaissance commands (curl, dnslookup, ping, telnet, traceroute) and socket-level tunneling via an embedded SSH client. Indicators of compromise include specific SHA-256 hashes and package names associated with TrickMo dropper applications and host applications. The malware retains unused permissions for NFC capabilities, suggesting a strategic approach to device filtering.
