VERY IMPORTANT

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.
