Prolexic has reported 45% increased DDoS attacks in Q4 of the last year. That is double than the number of attacks in the third quarter of the year 2011.
Paul Sop, Prolexic's chief technology officer, reported that there is shorter attack duration with bigger packer-per-second attack volume. Average attack bandwidth in Q4 2011 was 5.2Gbps (bits per second), 148 percent higher as compared to the third quarter. This is 136% increase on annual basis.
“We have seen a trend toward shorter overall attack duration, but with unprecedented high packet-per-second volume and lethal attack signatures,” said Sop. “This is a devastating cocktail that can quickly bring down even well protected sites and their mitigation providers. We are starting to see packet-per-second attack volumes that are simply off the charts.”
