Record-Breaking DDoS Attack Detected and Mitigated

A recent distributed denial-of-service (DDoS) attack attributed to the AISURU/Kimwolf botnet has set a new record, peaking at 31.4 Terabits per second (Tbps) and lasting only 35 seconds. This extraordinary attack was automatically detected and mitigated by Cloudflare, a leading cybersecurity firm.

The AISURU/Kimwolf botnet has been linked to a growing number of hyper-volumetric HTTP DDoS attacks in the fourth quarter of 2025. These attacks are characterized by their extremely high volume of traffic, which can quickly overwhelm a targeted system or network.
