LinkedIn passwords hacked
Business social network LinkedIn said it is investigating reports that more than six million passwords have been stolen and leaked on to the internet.
Although LinkedIn did not confirm if any user data had been hacked or leaked, researchers at UK web security company Sophos say they have confirmed that a file posted online does contain, in part, LinkedIn passwords "hashes." That's a way of encrypting or storing passwords in a different form.
Graham Cluley, a consultant with Sophos, recommended that LinkedIn users change their passwords immediately.
