Are DDoS Attacks Increasing or Decreasing? Depends on Whom You Ask

Distributed denial-of-service (DDoS) attacks remain unpredictable and dangerous for enterprises, but actual details on how the threat is evolving can differ substantially by the reporting source. Two reports released this week, one by Verisign and the other from Nexusguard, indicate a general increase in multivector attacks and an overall decrease in the number of DDoS attacks in the fourth quarter of 2017 compared to the prior quarter, but they differe on the details based on data gathered from their customer engagements.

Nexusguard reported a 12% decrease in DDoS attacks between the fourth quarter of 2016 and the same quarter in 2017, and a more than 16% drop in attacks between the third and fourth quarters last year. Verisign pegged the decrease in DDoS attacks during the same period at a somewhat higher 25% and said the number of attacks has continued to decrease from quarter to quarter.

Nexusguard says multivector, blended threats represented some 56% of recorded attacks last quarter while single-vector attacks accounted for just over 43%. Verisign, meanwhile, says a massive 82% of the DDoS attacks it mitigated in the fourth quarter of last year employed multiple attack types.
