The average DDoS attack quintupled in size to more than 26 Gbps and the maximum attack size quadrupled to 359 Gbps compared to the same period last year, according to Nexusguard´s “Q2 2018 Threat Report,´ the company said.
The quarterly report, which unbiasedly evaluates thousands of worldwide DDoS attacks, attributes the dramatic rise to IoT botnets and Satori malware exploits, which is a variant of the notorious Mirai malware. Communications service providers (CSPs) and vulnerable organizations will need to enhance bandwidth protection if they hope to stay ahead of the surging attack sizes.
Due to the increase in IoT-related malware exploits and the rampant growth of large-scale DDoS attacks, research conclusions point to the continued use of IoT botnets. Cyberattacks hit the 2018 FIFA World Cup as well as cryptocurrency-related businesses, maximizing revenue loss. For example, attacks on the Verge Network (XVG) caused a loss of 35 million XVG tokens, valued at more than USD 1.7 million.
Nexusguard analysts warn that CSPs and susceptible operations should enhance their preparedness to maintain their bandwidth, especially if their infrastructures don´t have full redundancy and failover plans in place.
Hackers favored attacks using universal datagram protocol (UDP), with more than 31 percent of all attacks leveraging this volumetric strategy. The connectionless protocol helps launch mass-generated botnets, which also saps host resources and can ultimately make them inaccessible. With nearly one-third of the worldwide Internet users, the US and China held their spots as the top two sources of attack traffic, contributing 20 percent and more than 16 percent of attacks, respectively.
