Hacking The Hypervisor doesnt protect against changing worlds in Minecraft Xbox 360 Edition

[XEN64]

I did some testing and found out that the hypervisor does not stop from people editing minecraft worlds, and I used a bug in Universal Minecraft Editor to fill the stack with A's and the game just straight up crashed, as well as the console.

Much like the hypervisor doesn't care about modified save data.
Idk what you're trying to achieve but we can modify save games on the 360 since forever.

interesting

this isn't new news, i've installed custom worlds as far back as 2012

i even downloaded a save file for portal that immediately unlocked all the achievements upon loading

afaik, the only thing with save files is device and profile ids. it's been known for a while that the 360 doesn't have protection against modified saves. it's not nearly as secure as the ones on the ps3 with pfd (protected file database).

The saves are signed, it's just that it uses the same key on every console which is funny. If OP is able to modify the stack they might be able to get a ROP chain but it likely won't lead to anything, there have been stack smash bugs in other games and nothing came of them. I'm not sure that OP knows what he's talking about though. How would they know they've filled the stack with As without a debug kit?

I may have added a blue dragon save to my system, but I can't remember. I'm near the end in it, and I don't really recall getting that far. it would've been many years ago if I had. I couldn't recall how to get them to work with the system, but I think it's just swapping device and profile ids with something like horizon. I think it even works on a legit system.

[godreborn]

oops, I thought we were talking about saves (my posts). nm. I don't have minecraft anyway.

The hypervisor doesn't care what you do "in" the game it cares more about what you're trying to do "outside" the game

I remember you could mod cod 4 online via profile gpd editing using USB xtaf and a gpd editor, this was patched long ago, it still works, though you have to have the original cod 4 with no updates installed

Even if you get homebrew running, it will only have access to the resources that were set aside specifically for Minecraft, you won't have full hardware access, more of a sandbox like dev mode

to be fair minecraft would require a lot of resources considering the nature of the game

It wouldn't have access to read or write to nand, dump CPU keys, overwrite the OS, hrmo etc, you can only modify the virtual memory space that the hypervisor gives to Minecraft, Minecraft is running Root, the 360 hypervisor is running Super Root, Minecraft runs in a virtual machine of sort, created by the hypervisor, which is enforced using crypto keys created by m$

All homebrew (full hardware access) requires you to bypass or exploit the hypervisor, which is easier said than done

well yeah, but i mean if you manage to break out into the sandbox that minecraft's given, you likely have access to full cpu, gpu and ram speeds, since minecraft is a pretty intense game for something like an xbox 360

Yeah

You'd have to load Minecraft Everytime you want to load homebrew, and you can't update the 360 if m$ decides to release a patch

Homebrew only, you will not load any iso or rips

doesn't seem all that different to back in the day when the only way to load homebrew on the 3ds was via launching the youtube app
