Kristoffer von Hassel height - How tall is Kristoffer von Hassel?

After wanting to play his father's video games but having parental blocks preventing it, five-year-old Hassel tried hacking into the Xbox Live system by trying different combinations of passwords. Eventually, he found a back door security glitch that allowed him first to enter the wrong password, then in the following screen to enter a series of spaces to unlock the system. After he had "exploited the security hole", Hassel's parents found him playing the restricted video games and sternly asked him how he gained access. After he showed them, Davies contacted Microsoft to let them know about the security problem. Microsoft responded “We’re always listening to our customers and thank them for bringing issues to our attention. We take security seriously at Xbox and fixed the issue as soon as we learned about it.” They also provided Hassel with a free year-long subscription to Microsoft Live Gold, four video games and $50USD.

Hassel is the son of Robert Davies, who works in computer security, and Jill Nyahay. They live in Ocean Beach, California. When the media started covering Hassel in early April 2014, he was enrolled in Kindergarten.

Kristoffer von Hassel (born 2009) is the world's youngest known hacker and notable for being the youngest "security researcher" listed on Microsoft's Security Techcenter as having exposed a security vulnerability. At the age of five, Hassel exposed security lapses in the Microsoft Live Xbox system, prompting wide media coverage, with some journalists highlighting the dropping age of hackers and their technology mastery.
