Microsoft has revealed that in the last week of August, it had thwarted a giant 2.4 Tbps DDoS attack targeting an Azure customer in Europe. This was 140% higher than 2020’s 1 Tbps attack & higher than any network volumetric event previously detected on Azure, it said on its blog.
The attack traffic originated from approximately 70,000 sources & from multiple countries in the Asia-Pacific region, such as Malaysia, Vietnam, Taiwan, Japan, & China, as well as from the US. “The attack vector was a UDP reflection spanning more than 10 minutes with very short-lived bursts, each ramping up in seconds to terabit volumes. In total, we monitored three main peaks, the first at 2.4 Tbps, the second at 0.55 Tbps, & the third at 1.7 Tbps,” Microsoft revealed.
The IT giant said attacks of this size demonstrated the ability of bad actors to wreak havoc by flooding targets with gigantic traffic volumes trying to choke network capacity. But Azure’s DDoS protection platform, built on distributed DDoS detection & mitigation pipelines, can absorb tens of terabits of DDoS attacks, said Microsoft. This aggregated distributed mitigation capacity can massively scale to absorb the highest volume of DDoS threats, providing customers the protection they need.
