Happy to announce that my write up is coming very soon, as in this week most likely. Stay tuned! This will be a two-parter, one being a write up of the core bug itself, the other being an end-user exploit to patch the kernel in a useful way.

🧵 Since its “new Xbox 360 software-only hacks” season I’d like to announce that some months ago I privately discovered a 17559 HV bug capable of making small patches to the kernel. With this, you can do things like disable LIVE/PIRS signatures and other kernel checks on a retail

@Byrom_90 @razzlelul hmmmm after taking a look at this it might be tricky to do a good patch. I was assuming it was some function that would return 1 or 0 if over the ping limit but its a cmp in the middle of another large function. will need to do some research on this for sure

@ihatecompvir @razzlelul All that should be required is a single patch to nop an address within xam if that's possible with this method. Dashlaunch patches the check at 81754230 on 17559.

@FiPE_ZOE @Grimdoomer Yeah we talked about it, I believe it is a completely different bug. His can actually touch hypervisor code and enable full homebrew, mine can't

@razzlelul should if they don't enforce the limit in the hypervisor itself. would be a good use case for something like this

@ihatecompvir would this also work to disable ping limit on system link? I'd assume so right?

I have disclosed this to Microsoft for them to either fix (or not) and then I’ll disclose it publicly in the future. I’ll be publishing a full write-up as it’s a pretty fun bug, albeit relatively simple

As of today I have a fully working software only hypervisor exploit for the latest xbox 360 retail dashboard 17559 (should work on almost any software version though). Here's what you need to know...

Almost out of ROP chain hell... Currently have 20 unique gadgets and 27,716 links in the chain. I implemented common functionality in macros which makes writing more complex aspects of the chain easier. Another day or so and I can move on to the third stage of the exploit (in C)

Kamala Harris has announced that, if elected, she will ban use of .chart format in rhythm games. KH: “The .chart format was created as a simple project file for the authoring tool Feedback. The fact that its spec has since evolved into a convoluted mess is a national disgrace”
