Microsoft Faces The Largest DDoS Attack in History

Microsoft has successfully avoided the largest Distributed Denial of Service (DDoS) attack in history. The company said that its Azure cloud service mitigated a total of 2.4 terabytes per second (Tbps) DDoS attack, which is the largest recorded DDoS attack to date.

Microsoft’s Senior Program Manager at Azure Networking, Amir Dahan, explained that the attack was carried out using a botnet of approximately 70,000 bots located mostly around the Asia-Pacific region. This included Malaysia, Japan, China, Taiwan, Vietnam, and some from even the United States.

Dahan only addressed the primary target of the attack as “an Azure customer in Europe.” No further details were shared on this topic.

A Microsoft executive said that the DDoS attack came in three short waves over the course of ten minutes. The first wave came at 2.4 Tbps, the second at 0.55 Tbps, and the third at 1.7 Tbps.

The attack was successfully minimized without the Azure service going down.

Before Microsoft disclosed its Azure attack, the largest DDoS attack in history was recorded at Amazon’s AWS division. It suffered a whopping 2.3 Tbps attack back in February 2020.

Dahan said that the largest DDoS attack that hit Azure before this one was 1 Tbps in Q3 2020. After that, Azure did not see an attack bigger than 625 Mbps all year.
