13.5M Device Botnet Launches 2 Tbps DDoS Attacks on Financial Services

A massive botnet of 13.5 million compromised devices is targeting financial services with devastating 2 Tbps DDoS attacks, representing a tenfold growth in one year. The botnet uses blockchain-based command-and-control infrastructure via Polygon to avoid traditional takedown methods, making it extremely resilient. Financial institutions face the highest risk, with FinTech companies bearing 44% of attacks, followed by banks at 23%, demonstrating the critical need for robust DDoS defense strategies. The multi-vector attack approach across network, transport, and application layers shows how sophisticated these threats have become.
