Microsoft acknowledged in an official blog post that it was likely the victim of the largest distributed denial-of-service attack ever.
A deluge of junk data with a throughput of 3.47 terabits per second and a packet rate of 340 million packets per second (pps) attacked an Azure client in Asia, according to Microsoft’s Azure DDoS Protection team. The DDoS attack is thought to be the largest ever recorded.
A Distributed Denial-of-Service (DDoS) attack is a type of cyberattack in which an attacker attempts to make a machine or network resource unavailable to its intended users by disrupting the services of the host connected to the network or computer.
Typically, the assaults begin by flooding the targeted machine or resource with multiple requests in an attempt to overwhelm the system and prevent legitimate requests from being performed.
The DDoS attack in November, according to Microsoft, was launched from 10,000 sources in at least ten nations. The United States, China, South Korea, Russia, Thailand, India, Vietnam, Iran, Indonesia, and Taiwan were among the countries represented. The assault lasted about two minutes in total.
According to the official Azure blog, the world saw a significant number of Distributed Denial of Service (DDoS) assaults in 2021. These attacks wreaked havoc on Blizzard games, Titanfall, Escape from Tarkov, Dead by Daylight, Final Fantasy, and a slew of other titles.
The current assault outperformed a 2.5Tbps attack that Microsoft had blocked earlier in 2021. Since then, the corporation has successfully countered three major attacks.
One of the attacks was a 3.25 Tbps UDP attack that occurred in four bursts and lasted over 15 minutes. The other was a 2.55 Tbps UDP flood attack with a single burst lasting over five minutes.
Given Azure’s DDoS protection infrastructure, Microsoft guaranteed its clients that they do not need to worry about protecting their workloads on Azure. The technology is based on DDoS detection and mitigation pipelines that are distributed.
Azure’s DDoS protection architecture is built to scale exponentially in order to absorb the biggest amount of DDoS attacks and provide customers with the best degree of security possible.
