Repeat DDoS Attacks the Norm in Q4 2015, 24 Attacks per Target on Average

During Q4, repeat DDoS attacks were the norm, with an average of 24 attacks per targeted customer in Q4, reports Akamai in its newly released Q4 2015 State of the Internet – Security Report. Malicious actors aren’t backing down, says Stuart Scholly, VP and General Manager of Security Business Unit: “They’re hammering away at the same targets over and over again, looking for a moment when defenses may be down.” Study found more than half of the Q4 attacks (54%) targeted gaming companies, with another 23% targeting the software and technology industry.

The largest attack of Q4 peaked at 309 Gigabits per second (Gbps) and 202 Million packets per second (Mpps). This attack targeted a customer in the software and technology industry and used an unusual combination of SYN, UDP and NTP attacks originating from the XOR and BillGates botnets. The attack was part of a sustained campaign in which the victim was targeted 19 times over an eight-day period, with additional attacks following in early January.
