A consultant at IT security and data protection firm Sophos has said that the leak of six million passwords from LinkedIn does not include the associated email addresses.
But he warned that it is "reasonable to assume that such information may be in the hands of the criminals". He advised the following:
All LinkedIn users [should] ... change their passwords as soon as possible as a precautionary step. Of course, make sure that the password you use is unique - in other words, not used on any other websites - and that it is hard to crack.
