Key metrics from the 1H 2022 Netscout DDoS Threat Intelligence Report / ISSUE 9: FINDINGS FROM 1ST HALF 2022

Despite a slight decrease in DDoS attack frequency toward the end of 2021, adversaries unfortunately ramped up their nefarious activities in 1H 2022. Not content to simply rest on their laurels, attackers increasingly used powerful DDoS-capable botnets to launch TCP-based direct path attacks and often tied them to sociopolitical and entertainment events – think war, politics, religion, and sports.

The end result is that adversaries are constantly innovating, trying new attack methods, vectors, and motivations. EMEA experienced a 7 percent increase in DDoS attacks, with many of those tied to the conflict between Russia and Ukraine. The APAC region experienced about 8,600 DDoS attacks per day – or a new attack launched every 10 seconds. The LATAM region experienced an increase of 125 percent in botnet-based TCP floods. And North America experienced 1.04 million DDoS attacks in the six-month period, with adversaries increasingly targeting cloud-related service providers and even primary schools.
