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.

Microsoft has announced significant upgrades to its Azure security protocols, including the purging of dormant tenants and the rotation of keys to prevent future breaches, particularly following a nation-state hack. The company claims to have made substantial progress on its Secure Future Initiative, focusing on enhanced authentication and defenses against potential attack vectors.
