Microsoft Recently Fought Off The Largest DDoS Attack In History

Microsoft says it recently fought off the largest DDoS in history, the attack was measuring a high of 2.4Tbps in August 2021. DDoS known as Distributed Denial-of-Service is a coordinated attack used to force websites or servers offline. This happens when there’s extreme stressing of the target system with so much traffic than it can handle.

The attack went on for 10 minutes and it was at an unnamed Azure customer in Europe. This beats the previous known largest DDoS attack by 140%. The previous record was at a peak of 2.3 Tbps targeted at Amazon Web Services.

Microsoft was able to absorb the high peak of 2.4Tbps malware. It later said it declined to 0.55Tbps thanks to its strong firewall.

A senior program manager at Azure said “The attack traffic originated from approximately 70,000 sources and from multiple countries in the Asia-Pacific region, such as Malaysia, Vietnam, Taiwan, Japan, and China, as well as from the United States,”

Microsoft didn’t waste time promoting its Azure systems. “Azure’s DDoS protection platform, built on distributed DDoS detection and mitigation pipelines, can absorb tens of terabits of DDoS attacks.”

“This aggregated distributed mitigation capacity can massively scale to absorb the highest volume of DDoS threats, providing our customers the protection they need.”

Microsoft recently advised its Windows 11 users to activate its Tamper protection security feature. This will prevent hackers from locking them out of their systems and eliminate ransomware.
