Germany 2020 was mostly about more: More frequent, faster, and complex attacks. There was one big exception, however: attack duration, which dropped more than 50 percent globally. Attacks were also more complex, as 15-plus vector attacks spiked 126 percent in popularity year over year. This adds up to some bad math for defenders: Shorter duration + increased complexity = less time to respond to increasingly difficult mitigation scenarios. This attack strategy will likely continue, further highlighting the vital role of advanced and automated DDoS technology. Impact Analysis We wanted to understand how much traffic traversing Germany's infrastructure is due solely to DDoS attacks. To find out, we created the DDoS Attack Coefficient (DAC). DAC represents the total sum of DDoS traffic traversing any given region or country in one minute. This allows us to identify the DDoS attack traffic observed by NETSCOUT traveling in and out of the country for the past six months at any point in time. Here, you can clearly see the massive jump in both bandwidth and throughput during March, the height of the pandemic lockdown.
