Akamai is worried about embedded and other devices becoming a "larger part of the attack landscape," Summers said. "People have built ways to crack into those devices, then install software that they ... can launch DDoS attacks from."
Compared to the second quarter, the total number of DDoS attacks Akamai measured was up only 2 percent, but the average attack bandwidth was up 80 percent in the third quarter, with the average peak packets per second up 10 percent.
Online entertainment, media and technology companies were the most targeted in the third quarter, the company said. Nearly 24 percent of DDoS attacks originated from the U.S., 20 percent were from China and 18 percent were from Brazil, Akamai said.
