iStock_000018807376_SmallLinkedIn issued a blog post today reporting that a data breach from 2012 compromised as many as 117 million users’ account credentials. The amount of compromised passwords was originally estimated to be close to 6.5 million.

It was initially thought only passwords were compromised during the 2012 breach, but now it’s shown that email addresses were compromised a well. LinkedIn has emailed users whose accounts the company suspects were compromised, and is encouraging users to begin using two-step verification processes when accessing LinkedIn.

Social media users are encouraged to regularly change passwords, and use different credentials on different networks and applications.
