Sudden! The Microsoft Azure platform suffered a record-breaking DDoS attack launched by the Aisuru botnet, with peak traffic reaching 15.72 Tbps and involving more than 500,000 infected IP addresses. Aisuru, dubbed a "Turbo Mirai-level IoT botnet" by Microsoft, mainly attacks by exploiting compromised IoT devices. Previously, its operator successfully invaded the TotoLink router firmware update server and infected approximately 100,000 devices. The multiple motivations of DDoS attacks are generally (retaliation, blackmail, market manipulation) and their low cost. IoT devices lack security and become the main source of botnets.
