attention after he exposed a security weakness that let him log into his dads xbox live account，without permission.kristoffers father，robert，noticed soon after christmas that his son was logging into his account and playing games that werent 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 dads 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 that is！”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.“were 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 kristoffers 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 fathers help，kristoffer will receive four games，50 and a years subscription(会员费) to xbox live from microsoft.5why did a san diego boy attract the gaming worlds attention?ahe is a security researcher.bhe designed a new software.che is addicted to playing games.dhe got past the lock of a
