Attack Traffic and Security

Akamai maintains a distributed set of unadvertised agents deployed across the Internet that log connection attempts, which the company classifies as attack traffic. Based on the data collected by these agents, Akamai is able to identify the top countries from which attack traffic originates, as well as the top ports targeted by these attacks. It is important to note, however, that the originating country as identified by the source IP address may not represent the nation in which an attacker resides. For example, an individual in the United States may be launching attacks from compromised systems anywhere in the world.

Akamai observed attack traffic originating from 185 unique countries/regions during the third quarter of 2013, up 10 over the previous quarter. China, which originated 35 percent ofobserved attacks, returned to the top spot this quarter after having been unseated by Indonesia in the second quarter. Indonesia, meanwhile, dropped back to second place after originating 20 percent of observed attacks – slightly more than half of the volume seen in the second quarter. The United States remained in third place as it originated 11 percent of observed attacks during the third quarter, up from 6.9 percent in the previous quarter.
