First half of 2020 saw a 151 percent increase in DDoS activity compared to the same period last year. One of the largest and longest attacks that Neustar has ever mitigated came in at 1.17 terabits-per-second (Tbps) and lasted five days and 18 hours. DDoS attacks are getting bigger, with the number of attacks sized 100Gbps and above growing 275 percent. The snowballing of growth across all DDoS metrics correlates with the COVID-19 pandemic.
