The U.S. government reported that the probes of it's Internet networks has quadrupled since September 11, 2001. The increases have been most noticeable from the servers in the Middle East and South East Asia. These probes are the initial moves for any hacker trying to find a Internet server vulnerable to attack. Such probes are easy to make, and free, automated software to make such probes is available on the Internet. Most of this increased probe activity is most likely the work of such amateurs (often called "Script Kiddies" or "weenies.") There has been a much smaller increase in actual attacks on U.S. government networks, but no increase in successful attacks. Most of the successful attacks continue to come from the United States (49 percent), South Korea (17 percent) and China (15 percent.) The Internet infrastructure in places like the Middle East and Southeast Asia is not substantial enough to support a lot of attacking activity. America has more than half the planet's Internet infrastructure, South Korea has the largest portion of users with high speed (cable or DSL) connections and China has a lot of black hat and anti-American hackers.
