Attack traffic now comes from every corner of the world, though some countries are responsible for more volume than others. According to Akamai’s second-quarter 2013 “State of the Internet” report, Indonesia is now the top origination source for attack traffic, based on IP address. Indonesia is responsible for 38 percent of attack traffic, followed in second place by China, which accounts for 33 percent of attack traffic.
AlienVault’s Open Threat Exchange data for October provides a different viewpoint. AlienVault reports that China has more malicious IP addresses than any other country in the world, followed in second place by the United States.
