In a somewhat nefarious climb to the top, Indonesia overtook China to become the top source of Internet attacks.

Attack traffic from Indonesia nearly doubled in the second quarter of 2013, according to Akamai's latest "The State of the Internet" report published Wednesday. From April to June, attack traffic out of Indonesia spiked to 38 percent, a 17 percent increase from the previous quarter, according to the report.

Indonesia claims the dubious top spot from China, which dropped to No. 2 on Akamai's list. China's share remained roughly consistent, Akamai said, with 33 percent of attack traffic originating from the country in the second quarter.

Rounding out the top 10 on Akamai's list of attack traffic by country: the United States, Taiwan, Turkey, India, Russia, Brazil, Romania, and South Korea. These ten countries were the source of 89 percent of attacks, said Akamai. In total, Akamai observed attack traffic originating from 175 unique countries/regions in the second quarter, two fewer than in the first quarter.

Akamai noted in the report that its "methodology captures the source IP address of an observed attack and cannot determine attribution of an attacker." Which basically means, the actual attackers aren't always in the country where their attack traffic is originating.

The security section of the report also said Akamai customers reported being targeted by 318 DDoS attacks in the second quarter, 54 percent more than the prior quarter, and that enterprise customers were the most frequently targeted.
