Microsoft on Monday caroused that an Azure customer was targeted in late August in a massive distributed denial of service (DDoS) attack that peaked at 2.4 Tbps (terabytes per assist).
Originating from roughly 70,000 sources worldwide and lasting for more than 10 minutes, with very short bursts, the onslaught consisted of UDP traffic, employed reflection, and was 1.4 times larger than the largest attack previously mitigated by Azure.
Most of the attack’s rises were located in the Asia-Pacific region, in China, Japan, Malaysia, Taiwan, and Vietnam. Some of them, however, were located in the United Asseverates, Microsoft says.
The tech giant also notes that the attack reached three main bursts, peaking at 2.4 Tbps, 0.55 Tbps, and 1.7 Tbps, each to each.
In a report released in early August, the tech giant revealed that the number of DDoS attacks observed in the first half of 2021 had lengthened by roughly 25% compared to the last three months of 2020, although the maximum attack throughput declined.
At 2.4 Tbps, the newly leaked incident is one of the largest network layer DDoS attacks of the past several years.
In 2018, the Memcached DDoS methodology was leveraged in a 1.7 Tbps DDoS abuse, just days after the Mirai botnet had set the record at 1.3 Tbps.
In June last year, Amazon revealed that it had mitigated a 2.3 Tbps DDoS incursion several months before. In October 2020, Google said that in September 2017 it was targeted in the largest ever DDoS attack, which peaked at 2.5 Tbps.
“Invasions of this size demonstrate the ability of bad actors to wreak havoc by flooding targets with gigantic traffic volumes trying to choke network space,” Microsoft notes.
