Microsoft Blocks Hacked Hotmail Accounts
Microsoft has blocked some Hotmail accounts after signs they may have been taken over by attackers. Affected people may be locked out until they verify their identity and secure their account.
Who is at risk
Anyone using a Hotmail account, especially people who reuse passwords or have not added extra sign-in protection, is most at risk.
What to watch for
Watch for unexpected sign-in problems, password reset messages you did not request, missing emails, or messages sent from your account that you do not recognize.
What to do
Immediately reset your Hotmail password to a new unique one, review your recent account activity, and turn on two-step verification if it is available.
