Recently, large-scale DDoS distributed denial-of-service attacks have been “crazy” again in Asia.According to the latest DDoS attack trend report of Microsoft, In November last year, Microsoft successfully alleviated DDoS attacks with the maximum traffic reaching 3.47 Tbps and Packets Per Second rate reaching 340 million PPS through its Azure DDoS protection platform.The attack, which specifically targeted Azure customers in Asia, was billed by Microsoft as the largest DDoS attack in history.Shortly after Microsoft mitigated the largest DDoS attack in history, hackers launched two massive DDoS attacks in December, one targeting 80 ports with 3.25 Tbps of UDP traffic,The other wave is the UDP flood attack targeting 443 ports and 2.55 Tbps traffic, both of which target Azure customers in Asia.Microsoft said the 3.47 Tbps massive Attack in November was the largest DDoS attack the company has faced since late August, when it mitigated a 2.4Tbps traffic attack targeting Azure users in Europe.The spectacular DDoS attack originated from around 10,000 botnets in countries around the world, including the United States, China, South Korea, Russia, Thailand, India, Vietnam, Iran, Indonesia and Taiwan.This 15-minute DDoS attack,Through Simple Service Discovery Protocol (SSDP), Connection-less Lightweight Directory Access Protocol (CLDAP), and Domain Name (DNS)System, Network Time Protocol (NTP), and other attack channels to launch UDP reflection amplification attacks on Port 80.There have been terabytes of large-scale DDoS attacks before, such as Google’s mitigation of the then record-breaking 2.54 Tbps DDoS attack in 2017.Amazon’S AWS Shield DDoS defense platform also detected an alarming 2.3Tbps Volumetric Strike in the first quarter of 2020.In August, Russian Internet giant Yandex was hit by an application-level DDoS attack that sent 21.8 million Requests Per Second (RPS).Several notable trends can be seen in Microsoft’s report, one of which is the trend toward DDoS attacks lasting more than an hour in the second half of 2021, as well as the increasing prevalence of multiple attacks such as the 3.47 Tbps DDoS of November.These more persistent DDoS attacks are a series of short but sustained attacks that can explode to terabytes of traffic in just a few seconds.Another important trend is that the gaming industry continues to be the most affected by DDoS attacks.With mobile games taking off in places like China, Japan, South Korea, Hong Kong and India, it’s no surprise that several recent DDoS attacks have targeted Asia specifically.
