Security firm Cloudflare disclosed that during the third quarter of 2025, a botnet dubbed Aisuru (also referred to as Kimwolf) carried out an enormous Distributed Denial of Service (DDoS) attack, achieving a traffic peak of 29.7 Tbps and setting a new record. This botnet, which harnessed an estimated 1 million to 4 million compromised devices across the globe, primarily set its sights on sectors including telecommunications, gaming, web hosting services, and finance. To sidestep detection, the attack utilized UDP carpet - bombing tactics, which involve randomizing packet attributes. While Cloudflare's automated defenses managed to thwart the attack, the company issued a cautionary note, highlighting that such assaults have the potential to indirectly cripple Internet Service Providers (ISPs) that aren't the direct targets of the attack.
