Yes, you're reading this right. A five-year-old by the name of Kristoffer Von Hassel discovered a security hole that allowed him to log in and make purchases via his father's account without knowing his password. The youngster discovered that after typing in the wrong password and reaching the second verification stage, inputting a space would give him access to the account.
The issue was reported to Microsoft by his father and fixed. Subsequently Kristoffer has been rewarded for his discovery with four free games, $50, a 1-year Xbox Live subscription and his name is now on the list of Microsoft's security researchers thanked for their contributions.
Now, I'm pretty sure this was just dumb luck on the boy's part and it's definitely not front page news material, so I'm putting it in the User Submitted News as an oddity rather than relevant news. Now, remember kids! Saying nothing at all sometimes opens many doors just like typing in a space sometimes opens your dad's virtual wallet.
