The 40-year old had a similar conviction in 2011, after having hacked the Facebook accounts of several employees of a media group, and made public some of the private contents.
He is also believed to have hacked the accounts of actors Steve Martin and Mariel Hemingway, as well as of a former CIA analyst Laura Manning Johnson.
Among the most famous of his actions was hacking the e-mail of former state secretary Colin Powell, and revealing an alleged affair with Romanian MEP Corina Cretu.
