Passwords belonging to up to 10,000 Hotmail users were exposed on an Internet site, but had since been taken down, Reuters reported.

Microsoft said the passwords had been removed from the website. Hotmail had blocked access to all affected accounts and was helping users to reclaim their accounts.
It said the attack did not breach of any Microsoft servers.
