A user in a Russian forum says that he has hacked and uploaded almost 6.5 million LinkedIn passwords, according to The Verge. Though his claim has yet to be confirmed, Twitter users are already reporting that they’ve found their hashed LinkedIn passwords on the list, security expert Per Thorsheim said.
To test if your account was one of those hacked. Go to this address and enter your password (you don’t need to enter your account name). http://www.leakedin.org/
If the system says your password was leaked.. we suggest you head to linkedin now and change it..
