How, given that we have total control over the firmware, has no one ever bypassed MS's hack checks?

    I don't own an xbox and don't really know anything about it.
    But I have heard that it is effectively impossible to play online even if you don't mod games, you can only "borrow" keyvaults from another console.

    How is this possible? Why can't the modified firmware just try to hide itself from the rest of the OS? I mean, it's at the "root of trust". Is Microsoft running arbitrary code on the console to do these checks? I can't find any technical explanation of this.

    Sorry if this is a dumb question.

    Microsoft has various checks on what runs on a 360.
    Hardware hacked machines run an older version of the hypervisor to enable the vulnerability that grants arbitrary code execution.
    MS can detect it and will remove you from their service.

    Stealth servers are basically the best you're getting on being online on a hardware hacked machine.

    Oh, there's a hypervisor? That explains it.

    Do we have arbitrary code execution on the hypervisor with that vulnerability? If so, could the running hypervisor be replaced by the exploit with a patched version of the current one?

    I just found this which helped me https://www.se7ensins.com/forums/threads/how-do-xbox-live-servers-work.1135011/

    That basically sums it up yes.

    It's possible but only few have achieved it due to the hypervisor

    Xbox live stealth is the big notable one, while they arent free to use it does let you bypass the checks you mentioned and keep you from getting banned(provided you arent doing anything dumb)
