A LinkedIn hack from back in 2012 is causing problems for users today.
It's been four years since 6.5 million encrypted passwords were stolen and posted onto a Russian hacker forum.
The company announced Wednesday morning that another 100 million LinkedIn members' emails and passwords have been released.
The company is contacting those users affected, but suggests changing your password if you had an account in 2012 on LinkedIn, or used the same password on any other sites. NOTICE FROM LINKEDIN
