Distributed denial of service (DDOS) attacks rose by 39 percent between the first half of 2018 and June of this year, Netscout Systems said in a new threat intelligence report.

During that 12-month period, attackers turned more attention to attacks of lesser sizes, what Netscout called “the juicy middle of attack sizes, resulting in staggering growth of 776 percent in attacks between 100 Gbps and 400 Gbps in size.”

Among the industry segments more frequently targeted during the period were satellite communications providers, with a 255 percent jump in attacks and wireless communications provider, with a 193 percent increase.

Netscout also said the Mirai malware “continues to dominate the IoT malware scene with a growing number of variants reported” in the first half of 2019.  Further on the IoT front, the company said that malware targeting IoT devices behind firewalls has been increasing.  It called those targets a “rich opportunity, considering that there are 20 times more IoT devices behind firewalls than directly connected to the internet.”
