Microsoft: DDoS attack at 2,4 terabytes per second

Microsoft said its Azure cloud service was able to stop a DDoS that reached 2,4 terabytes per second (Tbps).

The attack took place in late August, and was the largest DDoS attack ever recorded.

Amir Dahan, Senior Program Manager for Azure Networking, said the attack was carried out using a botnet that has about 70.000 bots and are mainly located in the Asia-Pacific region, such as Malaysia, Vietnam, , Japan, China, as well as the United States.

Dahan did not say much about the target of the attack as he described him only as an "Azure customer in Europe".

A Microsoft spokesman said the record-breaking DDoS attack came in three waves over a period of ten minutes, with the first at 2.4 Tbps, the second at 0.55 Tbps and the third at 1.7 Tbps. He added that Microsoft mitigated the attack without dropping Azure.

Prior to Microsoft's revelation, the previous DDoS record was from a 2,3 Tbps attack on Amazon's AWS division in February 2020.

Dahan said the previous major DDoS attack on Azure before the August attack was a 1 Tbps attack in the third quarter of 2020.

A few days after the Microsoft attack, a botnet called Meris broke another DDoS record - the record for the largest volumetric DDoS attack (volumetric DDoS attack).

According to Qrator Labs, the operators of the Mernet botnet launched a 21,8 million requests per second (RPS) DDoS attack in early September. It targeted a Russian bank that hosted e-banking on Yandex Cloud servers.
