Kristoffer's father, Robert, noticed soon after Christmas that his son was logging into his account and playing games that weren't appropriate for his age. When he asked how, Kristoffer showed him a hack that seems simple but is fairly impressive considering a 5­year­old boy found it.

　　Kristoffer would go to his dad's account and type in an incorrect password. That would take him to a password verifications screen, where he would simply tap the space bar repeatedly and then press “Enter”．

　　“How awesome is that！” said Davies, who works in online security himself. “Just being 5 years old and being able to find a vulnerability and getting attached to that. I thought that was pretty cool.” He told KGTV that Kristoffer has figured out three or four other “hacks”， including getting past the lock on a smartphone by holding down the “home” key for long enough.

　　Davies reported the vulnerability to Microsoft. And Microsoft acted, issuing a fix for it. “We're always listening to our customers and thank them for bringing issues to our attention，” the company said in a written statement. “We took security seriously at Xbox and fixed the issue as soon as we learned about it.”

　　The company has even included Kristoffer's name on a list of security researchers who have helped make online Microsoft products safer. For his discovery, or more accurately, for reporting it with his father's help, Kristoffer will receive four games, $50 and a year's subscription to Xbox Live from Microsoft.
