You may not make much use of the career referral service LinkedIn, but chances are that you or someone you know has an account with them. If so, you should take note that a 2012 data breach affecting more than 6 million of the site’s members is much worse than initially realized: It’s more like 117 million compromised passwords.

The site reported Wednesday that the 2012 hack by an unknown person or persons had actually withheld the total amount of information collected. CNN claims the passwords are currently being offered on the black market. While a person's LinkedIn profile may not be all that intriguing, the presumption is that many people use the same security logins for multiple internet, banking, and personal accounts.

While LinkedIn will alert the stolen account holders to change their passwords, it’s probably a good idea to revise your information regardless. A password manager can keep track of different logins for different sites, minimizing the chance of hackers being able to access the rest of your online life in a single breach.
