1. Albert Gonzales
The last hacker on our list of the biggest hackers the world has ever known, Albert Gonzalez, specialized in credit card hacks. Between 2005 and 2008, he was involved in the biggest credit card data theft in the history, getting his hands on the credit card information of users from Heartland Payment Systems and TJX Companies. He was caught in 2008 trying another credit card hack, and sentenced to 20 years in prison, the biggest sentence for any hack related crime in history.
