A 5-year-old boy has been able to hack into his father’s Xbox Live account by falsely entering the password with space keys, 10News reports.

The vulnerability has since been corrected. After booting up an Xbox One, Kristoffer Von Hassel would incorrectly enter his father’s password. After it took him to a verification screen, he’d use the space button trick to log on.

Von Hassel’s parents discovered the 5-year-old had accessed the account after they found him playing restricted games. The Von Hassels contacted Microsoft, who thenrewarded the boy with four games, $50 and a yearlong subscription to Xbox Live. Von Hassel is also listed online as one of the security researches who helped make the company’s systems safer.

“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.”

According to the boy’s father, it’s the third or fourth time Kristoffer has found the vulnerabilities in security systems. To see how Von Hassel accomplished his hack, check out the video above.
