Microsoft Azure fended off the largest DDoS attack recorded, peaking at 15.72 Tbps, attributed to the Aisuru botnet. This botnet, which has infected over 700,000 IoT devices, has shifted from simple attacks to renting out these devices for illicit proxy services. The rise of such threats underscores the vulnerabilities of poorly secured IoT devices.

The Aisuru botnet targeted Microsoft's Azure network with a DDoS attack of 15.72 Tbps from over 500,000 IP addresses. This attack, using high-rate UDP floods, is part of a trend of record-breaking DDoS incidents linked to the botnet, which exploits vulnerabilities in IoT devices.
