Every quarter for the last four years, content delivery network provider Akamai has issued a State of the Internet report that identifies the top sources of attack traffic, among other key metrics.
For the fourth quarter of 2011, China topped Akamai’s list of the top originating countries for attack traffic. China was responsible for 13 percent of total attack traffic overall, an increase from 8.6 percent in the previous quarter. China takes over from Indonesia, which previously held the top spot at 14 percent, but fell to 7.6 percent in the fourth quarter.
