A sophisticated Phishing-as-a-Service platform called Balonx Sistema, operated from Mexico, targets over 20 financial institutions through tiered subscriptions. The platform employs real-time WebSocket session hijacking to defeat multi-factor authentication, distributing a Spyroid-based Android RAT via fake security alerts. Since October 2025, over 1,100 victims' credentials have been harvested. The operation includes CallFlow, an AI-driven vishing module using GPT-4o-mini, ElevenLabs synthetic voice, and OpenAI Whisper for automated telephone fraud, eliminating human operators. The platform uses continuous domain rotation across 350+ domains since 2019, maintains centralized PostgreSQL infrastructure, and is openly promoted through Facebook groups. The operator, identified as 'balonx', manages a sophisticated criminal enterprise generating approximately $99,000 USD through subscription-based access priced between 3,000-6,000 MXN weekly.
