A hacker is trying to sell a database dump containing account records for 167 million LinkedIn users. The announcement was posted on a dark market website called TheRealDeal. LinkedIn suffered a data breach back in 2012, which resulted in 6.5 million user records and password hashes being posted online. It’s highly possible that the 2012 breach was larger than previously thought and that the rest of the stolen data is surfacing now. LinkedIn users who haven’t changed their passwords in a long time are advised to do so as soon as possible.”]
