If you’re a Hotmail user, next time you get an email from your “friend” that clearly isn’t from your friend at all, select the “My friend’s been hacked!” option from the “Mark as” menu and from there, Microsoft will investigate the report and then help your friend recover their account.
Additionally, Microsoft has also made it harder for users to set easily hackable passwords to begin with. Users will no longer be able to set simple passwords like “password” and “12345678”.
