A post on the TheNextWeb site indicates that a Norweigan IT webite, Dagens IT, reported the breach. That site indicates that 6.5 million encrypted LinkedIn passwords have been posted to a Russian hacker site.
LinkedIn has responded that they are looking into the breach.
To be safe, LinkedIn users should change their passwords immediately.

Not a lot of info from LinkedIn on this so far today. Two earlier tweets indicating they are investigating and haven’t yet confirmed that a breach occurred.
A further tweet and post on one of their blogs at 2:30pm indicating they are still investigating, have still yet to confirm a breach has occurred, and a recommendation the LinkedIn users change their passwords and follow password best-practices (and they provide an excellent list of them).
Please change your LinkedIn password if you have not yet done so – and take a look at the password best practices in the LinkedIn post so that you use a password that is harder for the hackers to crack.
Not a bad time to change the passwords on your other accounts. If you use Google, consider enabling Google’s two-factor authentication, especially if you are using it for your law practice. See instructions on how to do this here.
You could also consider using a password manager like LastPast. It is a cross-platform and device tool that will safely store and remember passwords for you, thereby making it easier to use different and stronger passwords for your various accounts.
