Xbox One Exploit Proof of Concept Released, Based on Chakra Exploit
- colemickens 9y agoI don't know much at all about the Xbox One architecture (and what I do is from public information obviously), but it seems safe to assume that this exploit would only land in the "Application" portion of the system. As I understand there are two (three?) hypervisor-level isolated portions of the system... particularly for cases like this in order to prevent a compromised application from being able to enable piracy of the "GameOS" portion.
- gambiting 9y agoThere are actually 3 different OSes running on the Xbox One. Applications are in their own OS, so any "kernel" exploit would only grant them access to that very limited OS that can't run games. Unless, of course, they somehow manage to escape that container and force VM to run their own modified version of GameOS.
- my123 9y agoA modified version of Hyper-V called NanoVisor is used. Apps run in SystemOS, which is already accessible officially even through other ways... GameOS and HostOS use a stripped-down version of the NT kernel, compiled differently and without binary compat.
- TazeTSchnitzel 9y agoYes, can't anyone make a Windows Store app for Xbox One?
- my123 9y agoAnyone can, that's right ;) Every Windows Store(UWP) app that isn't a game* is automatically pushed to Xbox devices also, except if the developer opts out. * for games, it's separately handled for validation

- watsonc73 9y ago"I do not have an xbox one and cannot verify that the exploit indeed works. With that being said, there’s enough hints pointing to this being real so if you have an XBox running on the affected firmware, feel free to give it a try and comment." I've no doubt this exploit is legit but it would be nice for reporters to actually verify these issues themselves before posting online. The above basically reads to me I'M TOO LAZY TO CHECK MYSELF
- spondyl 9y agoI would struggle to call wololo a reporter. The site is more of a "scene" blog so I don't actually know what resources he has. For example, you might expect Ars Technica to own an Xbox One but wololo may not have one himself but yeah, I know what you mean. EDIT: Oh, I overlooked the part where he says "yup, I still don’t have an Xbox One…" so there ya go
- lawl 9y agoHe said he doesn't have an xbox one in TFA. What do you want him to do? Go buy one so he can make a blog post?
- aaossa 9y agoHe could have ask a friend to apply the exploit, is a matter of responsibility because you need proofs to support your statements. What would happen if the exploit is not real and he called it out incorrectly?
- icebraining 9y agoThe author stated that a proof of concept was released. This is a verifiably true fact. Nowhere was it claimed it worked, and in fact that's quite clear by the "unconfirmed" in the title and the "[w]e have not confirmed if this exploit works" in the first paragraph.
