The 2012 LinkedIn hack refers to the computer hacking of LinkedIn on June 5, 2012. Passwords for nearly 6.5 million user accounts were stolen. Yevgeniy Nikulin was convicted of the crime and sentenced to 88 months in prison.
Owners of the hacked accounts were unable to access their accounts. LinkedIn said, in an official statement, that they would email members with instructions on how they could reset their passwords. In May 2016, LinkedIn discovered an additional 100 million email addresses and passwords that had been compromised from the same 2012 breach.
