DDoS Threat Report 2017 Q1

During Q1 2017, application-layer attacks like HTTP GET/POST Flood predominated, overtaking volumetric-based attacks.

  • In Q1 2017, the number of DDoS attacks observed by Nexusguard registered a 380% year-on- year growth, suggesting that DDoS attacks occurred more frequently than the same period a year ago.
  • Uncommonly fierce attacks were observed in Q1 2017 - much more so than in preceding quarters. An enormous 275Gbps attack took place during Valentine’s Day and a lengthy attack spanning 4,060 minutes occurred over the Chinese New Year.
  • The percentage of days with sizeable attacks (larger than 10Gbps) grew considerably between January (48.39%) and March (64.29%).
  • HTTP attack counts and total attack counts increased over Q4 2016 by 147.13% and 37.59% respectively.
2017_Q1

 

Q1 2017 saw increased frequency of DDoS attacks compared with corresponding quarters in 2015 and 2016, during which attacks were less scalable and frequent. 2017 attack counts increased by 231.12% over Q1 2015 and 379.84% over Q1 2016. The turning point, when gigantic, continuous attacks began to wreak havoc, appears to be Q4 2016, reflecting a ripple effect of increased Botnet activity that occurred in the year’s final quarter.
