The Register has posted a report that spammers have cracked the protection of Windows Live and they were able to create thousands of email accounts.

Websense says that the spammers installed a bot on computers and then it established connections on the Windows Live mail service. It was able to bypass the Captcha, which stands for “completely automated public Turing test to tell computers and humans apart,” requirement about a third of the time.

“Some customers were actually flagging the mail as legitimate because it was coming from Microsoft Live. Clearly, (spammers) are using the fact that (the services) are legitimate,” said Dan Hubbard of Websense.
