Over a third of cyber-attacks come from China, according to U.S.-based content delivery network Akamai Technologies, with the nation once again topping the global charts for hacking.
The report uses measurements from monitoring systems – which it calls "unadvertised agents" -- deployed across the internet which log connection attempts. Akamai then assesses whether these attempts are "attack traffic".
In the third quarter of 2013, China originated 35 percent of these attacks, Akamai said, up from 33 percent in the previous quarter. China overtook Indonesia, who had taken a surprise lead in the second quarter and since fallen back to second place with 20 percent of attack traffic. The U.S. was in third, ahead of Taiwan and Russia. Akamai state that It is important to note that the originating country as identified by an IP (internet protocol) address may not represent the nation in which an attacker resides.
