What happened? Microsoft has revealed that it can use the company's Azure cloud computing service to reduce a 2.4 Terabytes per second (Tbps) DDoS attack targeting one of its customers. By doing so, the tech giant has successfully fended off one of the largest distributed service-related attacks ever recorded.
Amir Dahan, Senior Program Manager at Azure Network, explained how the attack occurred at the end of August. The attack involved nearly 70,000 "exporters" from the Asia-Pacific region, including Malaysia, Vietnam, Taiwan, Japan and China. The United States was also mentioned as a country with different capabilities.
The major DDoS attack was executed in three short steps of over 10 minutes. The first wave increased at a rate of 2.4 Tbps, the second at 0.55 Tbps and finally the third wave rose at 1.7 Tbps.
The goal of a DDoS attack is to flood a website or service with a very high level of traffic. Uncontrollable, effectively forcing the target offline. It is executed by a network of malware-infected devices, allowing an attacker to take control of them remotely.
Despite the record number of attacks, Microsoft has asserted that it cannot "thanks to the distributed adversary capacity, which could" have the broad scope to accommodate the largest volume of DDoS threats" to their infrastructure influence. Azure security platform is able to handle tens of terabytes of DDoS attacks without affecting customers.
The largest DDoS attack before the announcement was the 1 terabyte per second attack that occurred last year in the third quarter of 2020, Dahan said. This year, despite reporting a 25 percent increase in attacks compared to the fourth quarter of 2020, the Microsoft Azure cloud platform did not experience a DDoS attack of more than 625 Mbps in the first half of 2021. The second attack prevented the largest DDoS attack on record Not bad at all for potential Microsoft vendors.But the pride of the biggest attack not yet recorded belongs to Google, which It reduced 2.54 terabytes per second in 2017.
Microsoft reduces DDoS attack at 2.4 terabytes per second, one of the largest attacks ever recorded
