She said Microsoft said it was able to mitigate a DDoS attack with a traffic volume of 2.4 terabytes per second in August.
The attack targeted an Azure client in Europe, and was 140 percent higher than the highest attack bandwidth volume the software giant recorded in 2020.
It also exceeds the peak traffic volume of 2.3 terabytes per second, the previous largest attack, directed at Amazon Web Services last year.
The company says the attack lasted more than 10 minutes, with short-lived bursts of traffic peaking at 2.4 terabytes per second, 0.55 terabytes per second, and 1.7 terabytes per second.
DDoS attacks are commonly used to force websites or services to go offline. This is thanks to the influx of traffic that a web host cannot handle.
It is usually conducted through a network of bots, a network of devices that have been hacked with malware to control them remotely.
Azure was able to stay online throughout the attack. This is thanks to its ability to accommodate DDoS attacks with traffic volumes of tens of terabytes per second.
“The attack traffic originated from about 70,000 sources,” explains Amir Dahan, Senior Program Manager for the Azure Networking Team at Microsoft. It included multiple countries in the Asia Pacific region. Such as Malaysia, Vietnam, Taiwan, Japan and China, as well as from the United States.
And while the number of DDoS attacks increased in 2021 against Azure. The maximum attack traffic size was reduced to 625 Mbps before the 2.4 Tbps attack.

The company does not mention the name of the Azure customer in Europe that was targeted. But such attacks can also be used as a cover for secondary attacks that try to spread malware and infiltrate company systems.
Amazon Web Services previously held the record for mitigating the largest DDoS attack. An attempt with a traffic volume of 2.3 terabytes per second exceeded the previous record of 1.7 terabytes per second. maintained by NetScout Arbor in March 2018.
Attacks of this scale demonstrate the actors’ ability to wreak havoc. This is done by flooding targets with massive traffic volumes in an attempt to throttle network capacity.
