According to the Verisign DDoS Trends Report for the second quarter of 2016, the number of distributed denial of service (DDoS) attacks increased by 75 percent year over year.
The average peak attack size in the second quarter was 17.37 Gbps, an increase of 214 percent over Q2 2015. Fully 75 percent of attacks peaked over 1 Gbps, and 32 percent exceeded 10 Gbps.
The largest and fastest DDoS attack detected by Verisign in Q2 2016 peaked at 256 Gbps for about 15 minutes before settling in at more than 200 Gbps for almost two hours.
Sixty-four percent of DDoS attacks detected in Q2 2016 employed multiple attack types, indicating that DDoS attacks continue to increase in complexity.
Forty-five percent of DDoS attacks targeted the IT services industry, followed by financial services (23 percent) and the public sector (14 percent).
The Kaspersky DDoS Intelligence Report for Q2 2016 found that 77.4 percent of resources targeted by DDoS attacks were located in China. The three most targeted countries for Q2 2016 were China, South Korea and the U.S.
While most attacks lasted no more than four hours, 8.6 percent lasted 20-49 hours, and 4 percent last 50-99 hours. The longest DDoS attack in Q2 2016 lasted for 291 hours (12.1 days), a significant increase over the previous quarter's maximum of 8.2 days.
Over 70 percent of all attacks detected by Kaspersky in Q2 2016 were launched from Linux botnets, almost twice the number for the previous quarter.
Just under 70 percent of all command and control (C&C) servers were located in South Korea, followed by China (8.1 percent), the U.S. (7.1 percent), Russia (4.5 percent) and Brazil (2.3 percent).
And the Nexusguard Q2 2016 Threat Report states that the number of DDoS attacks increased by 83 percent to more than 182,900 attacks in the second quarter.
The most targeted countries seen by Nexusguard were Russia, the U.S. and China.
"We were surprised to see an increase in DDoS attacks this quarter, especially as hackers experiment with ransomware, phishing schemes and other data-grabbing methods for monetary gain," Nexusguard chief scientist Terrence Gareau said in a statement. "Organizations can expect cyber attacks to continue growing in frequency this year, especially with more attention on the Summer Olympics and the November election season in the U.S."
"The results from this quarter also show how important it is to not only protect your website, but also to plan for new payloads and attacks on your infrastructure," Gareau added.
