Intelligent Platform grew significantly in the second quarter as customers of all sizes IPv6-enabled their Web sites ahead of the launch. Attack Traffic and Top Ports Attacked Akamai maintains a distributed set of agents deployed across the Internet that monitor attack traffic. Based on 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. Akamai observed attack traffic from 188 unique countries/regions during the second quarter of 2012. This was up from 182 in the first quarter, with China remaining the single largest volume source of observed traffic at 16 percent. The U.S. experienced a slight increase in originated attack traffic while staying in second place with 12 percent. Turkey rounded out the top three with a slight increase in the second quarter to 7.6 percent. Nine out of the top 10 countries remained consistent, with the exception of Italy displacing Germany from the list. South Korea saw the most significant decrease in attack traffic originations among the top 10, dropping from 4.3 percent in the first quarter of 2012 to 2.1 percent this quarter. The concentration of observed attack traffic targeting the top 10 ports dropped to 62 percent in the second quarter from 77 percent in the first quarter. The decline is largely attributable to fewer attacks against Port 445 after an unusually large increase in the first quarter. Port 445 was the single-most targeted in the second quarter, accounting
