Xbox hack allows unsigned code

You may now run unsigned code on any xbox. Discovered by GliGli, the exploit requires a chip, but works on any 360: "it sends little pulses to the processor in order to destabilize the console and make it believe a modified CB is correctly hashed and signed. This operation doesn't succeed every time, but it is repeated till it works." [logic-sunrise via Hack a Day]

That is dedication and some deep, deep wizardry.

  It sounds a little like the mechanism some unlicensed NES carts used to defeat the old Nintendo lockout chip, actually.
  
  I’m surprised that all the variations on the 360 are still similar enough for the exploit to work in all of them, too.

    Yep, the 10NES chip could be reliably defeated by a voltage spike, and wasn’t glitching the power supply what allowed geohot to crack the PS3′s hypervisor?
    
    If you can get that level of access to a system you can cause all kinds of interesting failure modes. Truly secure hardware would brick the instant someone opened the case the wrong way. Consumer stuff isn’t even close to that level of anti-tamper (with the possible exception of CableCARD, and those are considered high-grade anyway, being the cableco’s property)

It violates the Xbox Terms of Service, just like any other console which has been modded or even opened by anyone not Microsoft. A console, once sensors within report it has been opened, is permanently banned from use on Xbox Live. Do that & be banned from Xbox Live; your choice.

  Yes, if it lets me run homebrew, kinect hacks, unlock the processing for any number of non-game uses.

  There are no chassis-intrusion sensors in the 360. What happens is they can query the DVD drive firmware (which is what most modchips mess with).
  
  Or, you know, someone mods their console and outright cheats on live, which they catch really quick.

@ Anon_etc . . . How very Borg of you. You will be assimilated into Xbox live!

  I kind of was coming in here to remind everyone of the same thing, only without the condescending parent tone.
  
  So, yeah. If Microsoft catches you (and it’s basically when, not if), you can look forward to your console being banned from connecting to Xbox Live. Ever. If you’re okay with that, enjoy.

  I already have been.

And it only took seven years! Wow, that was fast. [not picking on the people that made the hack, I would have no hope of doing so. Just pointing out that it took a looooong time for this to be accomplished.]

  Yeah to be honest about it MS should be congratulated for pulling this off that it took that long to be hacked.
