The Akamai report also details Internet attack traffic patterns, which show the United States accounting for an increasing share of Internet attacks, with 12% of all attack traffic originating from this country.

"The United States remained in first place during this period, responsible for nearly one-eighth of the observed attack traffic -- slightly more than in the prior quarter," Akamai writes.

Previously, the United States accounted for 11% of worldwide attack traffic. Russia, meanwhile, dropped from 10% to 8.9% and China dropped from 11% to 8.2%.
