We’re receiving reports via Neowin that thousands of Hotmail passwords have been leaked via pastebin.com, a tool used primarily by developers to share code snippets.
Neowin claim to have seen part of the list posted and can confirm the accounts are genuine and most appear to be based in Europe. The list includes details of over 10,000 accounts starting from A through to B, which implies there may very well be additional lists from C-Z.
Microsoft owned Hotmail, MSN and Live.com accounts are believed to the only addresses leaked.
If you have an email address ending with any of the above, change your password and security question immediately.
This is breaking news, we will update if and when we receive more details.
