Aisuru Botnet Drove Record-Breaking Multi-Terabit DDoS Attacks

Researchers and network defenders linked the Aisuru botnet to a wave of hyper-volumetric distributed denial-of-service attacks that pushed internet-scale flooding to new highs. Reports described attacks reaching 11.5 Tbps and later 22.2 Tbps with 10.6 billion packets per second, with one major incident lasting about 40 seconds and being automatically mitigated by Cloudflare. Coverage from Cloudflare, The Register, Cybersecurity Dive, and QiAnXin XLab said the botnet helped fuel a broader rise in DDoS activity and turned parts of the internet into what one report characterized as a terabit-scale stress test.

Government and industry tracking indicated the botnet was not an isolated spike but an active threat affecting organizations across regions, including the UK. Germany's BSI published an Aisuru botnet profile as defenders continued cataloging its infrastructure and behavior, while media reports said British businesses were hit by record botnet-driven barrages. Across the referenced reporting, Aisuru emerged as a large-scale botnet associated with compromised devices and capable of launching short, extremely intense floods that set new benchmarks for DDoS volume and forced providers to rely on automated mitigation at massive scale.
