10 Most Infamous Hackers Who Wreaked Havoc on the World

7. Vladimir Levin

In 1994, Russian-born system administrator Vladimir Levin paid $100 for details on system access deep inside Citibank’s network. These access routes had been cultivated by a group who intended to test their ability before ceasing to use the network. Once Levin paid for access, though, he and six others transferred $10.7 million of Citibank’s money to accounts around the globe. The bank (shockingly) took notice and launched a worldwide manhunt for Levin, eventually nabbing him in London in 1995. He was sentenced to three years in jail and a fine of $240 grand. Here’s the kicker, though: about $400,000 of the stolen money has never been recovered, meaning Levin — or someone close to him — may have gotten some kind of pay day after all.
