There has been a 168% increase in DDoS attacks in Q4 2019, compared with Q4 2018, and a 180% increase overall in 2019 vs. 2018, according to Neustar.
The company saw DDoS attacks across all size categories increase in 2019, with attacks sized 5 Gbps and below seeing the largest growth. These small-scale attacks made up more than three quarters of all attacks the company mitigated on behalf of its customers in 2019.
DDoS attacks increase, take varied forms
In 2019, the largest mitigated threat, at 587 gigabits per second (Gbps), was 31% larger than the largest attack of 2018, while the maximum attack intensity observed in 2019, 343 million packets per second (Mpps), was 252% higher than that of the most intense attack seen in 2018.
However, despite these higher peaks, the average attack size (12 Gbps) and intensity (3 Mpps) remained consistent year over year. The longest single, uninterrupted attack experienced in 2019 lasted three days, 13 hours and eight minutes.
Though the number of attacks increased significantly across all size categories, small-scale attacks (5 Gbps and below) again saw the largest growth in 2019, continuing the trend from the previous year.
The combination of DDoS-for-hire and botnet rental services has made DDoS attacks much easier to execute, but the fact that perpetrators seem to be in many cases choosing to engage in small-scale attacks suggests that their goal may often be something other than taking a site completely offline.
“Large, headline-making DDoS attacks do still take place, but many cybersecurity professionals believe that smaller attacks are being used simply to degrade site performance or as a smokescreen for other forms of cy ..
