San Diego's KGTV has a cool profile of Kristoffer Von Hassel, a five-year-old who discovered a security hole in the Xbox One account login. Kristoffer accidently managed to log in to his father's Xbox One account without knowing the password, according to the news station. He did this simply by entering spaces into the password prompt after failing to punch the right password in the first time.
A five-year-old boy who managed to accidentally hack into his father's Xbox One account has received gifts and an official thank you from Microsoft for helping the company discover the security hole. His father Robert Davies is, interestingly enough, a security researcher. Shortly after Christmas he verified the exploit, recorded it and sent the video to Microsoft. Microsoft later patched the vulnerability out.
Microsoft was grateful, and rewarded Von Hassel (and his dad) by officially acknowledging him a Microsoft Security Researcher for March 2014, giving him $50, four Xbox One games, and a year of Xbox Live Gold.
"We're always listening to our customers and thank them for bringing issues to our attention," Microsoft said in a statement. "We take security seriously at Xbox and fixed the issue as soon as we learned about it."
