The volume of distributed denial-of-service (DDoS) attacks rose dramatically in the second quarter, according to VeriSign's latest DDoS trends report. In the second quarter, VeriSign reported a 216 percent increase in the average attack size from the first quarter. Year over year, the average DDoS attack size grew 291 percent. During the second quarter, VeriSign also recorded a new record peak attack size of 300 gigabits per second. In addition, VeriSign reported that it repelled multiple 200-plus gigabit-per-second DDoS attacks within a 24-hour period. The media and entertainment market vertical was a primary target of attackers, representing 43 percent of attacks VeriSign saw in the second quarter. Reflection amplification attacks using the Network Time Protocol (NTP) were a primary attack technique for generating large DDoS floods. While attack techniques have not changed over the last quarter, VeriSign found that attackers are not as interested in going after the application layer as much; only 10 percent of attacks targeted the application, down from the 30 percent reported in the first quarter. Here are key findings from the report.
