FBI agents spent two years undercover tracking the international "carding" network, locating the cyber thieves and disrupting their activities. They said the hackers used the Internet to steal and sell victims' credit card, bank account and other personal information.

The 24 people arrested include 11 spread throughout the United States, from Wisconsin to Georgia. The others were caught in Europe and Japan.

Four more defendants are still on the loose.
