Microsoft successfully mitigated a 3.47 Tbps distributed denial-of-service attack that was targeted at one of its Azure customers from Asia, the company reports in an Azure blog post on DDoS attack trends for Q3 and Q4, published on Tuesday.

This is almost 1 Tbps more than the previous largest DDoS attack, reported in October 2021, which had an attack rate of 2.4 terabytes per second at its peak.

Alethea Toh, product manager for Azure Networking, says in the blog post that the company believes this latest attack is "the largest attack ever reported in history." The post does not mention the exact date or month when the attack took place, but says that it lasted for approximately 15 minutes and originated from approximately 10,000 sources across multiple countries, including the United States, China, South Korea, Russia, Thailand, India, Vietnam, Iran, Indonesia and Taiwan. At its peak throughput of 3.47 Tbps, the DDoS attack attained a packet rate of 340 million packets per second.
