ThreatFabric researchers discovered StreamRat, a sophisticated Android banking trojan distributed through Meta and TikTok advertisements disguised as a free TV-streaming service targeting Spanish-speaking users. The campaign reached approximately 570,000 potential victims, primarily in Spain. StreamRat employs a two-stage installation process, utilizing a dropper that implements internet-blocking mechanisms via non-functional VPN connections. Once installed, the trojan abuses Accessibility Services and MediaProjection API to provide operators with near-complete device control, featuring VNC and hidden-screen control, UI-tree collection, keylogging, credential-stealing overlays, and screen-blocking capabilities. The malware appears designed as a Malware-as-a-Service offering, with a sophisticated control panel supporting multiple user roles and WebSocket-based C2 communications.

Mirax is a newly identified Android Remote Access Trojan operating as Malware-as-a-Service, actively targeting European users, particularly in Spanish-speaking regions. Distributed through Meta advertisements and GitHub-hosted droppers, the malware has reached over 200,000 accounts. It employs sophisticated techniques including dynamically fetched HTML overlays, comprehensive keylogging, and remote device control capabilities. A distinctive feature is its integration of SOCKS5-based residential proxy functionality, transforming infected devices into proxy nodes that enable attackers to route traffic through legitimate residential IP addresses. This capability allows operators to bypass geolocation restrictions and evade fraud detection systems while conducting account takeovers and transaction fraud. The malware uses commercial-grade obfuscation through Golden Encryption and establishes persistence through Accessibility Service abuse.
