Aisuru Botnet Powers Record DDoS Attack Peaking at 29 Tbps

The Aisuru botnet continues to be responsible for record-breaking distributed denial-of-service (DDoS) attacks, web performance and security firm Cloudflare reported this week. 

A new record DDoS attack was mitigated by Cloudflare in the third quarter of 2025. The attack peaked at 29.7 terabits per second (Tbps) and 14.1 billion packets per second (Bpps).

“The 29.7 Tbps was a UDP carpet-bombing attack bombarding an average of 15K destination ports per second. The distributed attack randomized various packet attributes in an attempt to evade defenses,” Cloudflare explained.

The previous record, also attributed to Aisuru, peaked at 22.2 Tbps and 10.6 Bpps.

Aisuru, dubbed a TurboMirai-class IoT botnet, has been responsible for many hyper-volumetric DDoS attacks. 

Powered by compromised devices such as routers, CCTV cameras, and DVR systems, the botnet is offered under a DDoS-for-hire model. Customers can also use the botnet for residential proxy services, which can ...
