Microsoft Corp said that passwords belonging to some users of its Hotmail email service were exposed on an Internet site, but had since
been taken down.
The company did not say how many users were affected, but some reports suggested that passwords to more than 10,000 accounts were exposed.
The accounts are genuine and look like they are mostly Eurpean users who use the @hotmail.com, @msn.com and @live.com domains. More specifically the leaked accounts include usernames that begin with ar to bl.
If your a Windows Live user now might be a good time to go and change your password. Actually, it is good practice to regularly change your passwords.
The software company Microsoft said the exposure of the passwords was not a breach of any Microsoft servers.
