Hackers Have 20 Percent Of Microsoft Login Credentials

Security experts continue to hammer home the point that reusing login credentials across multiple sites is a bad thing, but now Microsoft gives us an insight into just why it is so bad to reuse passwords.

According to Microsoft Account group manager Eric Doerr, hackers have access to some 20 percent of all Microsoft account system (formerly Windows Live ID) logins, which cover services such as Hotmail, Messenger and SkyDrive. These logins have not been compromised from the Microsoft server, but are instead based on login information leaked from other sites.
