Marking a new frontier for DDoS attacks

The year 2025 marks a fundamental paradigm shift in the DDoS threat landscape. The changes observed are not merely incremental; they represent a new reality defined by unprecedented scale, algorithmic speed and a complete transformation of the underlying attack infrastructure.

Terabit-scale distributed denial-of-service (DDoS) attacks, once a rare hundred-year storm-level event, now happen regularly to major cloud and telecommunications providers.

In 2025, massive new botnets emerged, including Aisuru and Kimwolf. Aisuru set a new global benchmark for volumetric carpet-bombing DDoS attacks, achieving a record-breaking 29.7 terabits per second (Tbps). These botnets are created and maintained by cybercriminals who provide DDoS-for-hire services, enabling even low-skilled actors to launch multi-Tbps attacks.
