Hacking IOSU / Kernel exploit

[OptimusDark]

Hello,

Sorry if my question is redundant, I tried to search an explanation of the differences between a kernel and IOSU exploit. But didn't find a clear answer.
IOSU refers to wii U firmware ?
Kernel exploit is not supposed to be the best exploit level reachable ? from it everything can be modified ?

Thanks for shedding theses lights

Kernel access would give you full memory control and decryption access, but security (on the Starbuck) is handled by IOSU and beyond reach of the kernel

In the Wii U terminology, kernel exploit means (usually) related to full control of the PowerPC/ppc/espresso(3 cores) by escalating privileges in kernel/CafeOS which controls mainly everything but security.

An IOSU exploit is for the ARM/Starbuck which mainly handles security of Wii U's hardware and software.

Hello,

Thx for the precisions. It's more clear to me now.
In the meantime I searched google and found https://fail0verflow.com/blog/2014/console-hacking-2013-omake.html : the video, is very interesting, though very long.
I'm beginning to understand what's coming in terms of exploit (see the "hacking wii u" topics).
It seems that failoverflow found the common decryption keys and the per console file system encryption key that will allow to add/remove wii u apps. But, since there is no IOSU exploit (security checker) yet, I don't think that we will have the ability to run homebrews. At best, what's should be easy to produce is a backup transfer apps that will allow to sign an iso with the per console key (the wii u game ares already signed for launch time check).
Any way, hacking the wii u in only one month is very impressive.

Well comex completed the IOSU exploit in 1 month. So a IOSU exploit did exist, but not public

Plus it's been patched since then.

 

[night_hawk]

Yes, I just did want to point out that an IOSU exploit was found

A birdy told me Nintendo was tipped off for some $. Anything really permanent cannot occur without an IOSU exploit and anything else can and will be patched. So essentially f0f did it, showed "proof" and cashed in. Birdies can always chirp lies but that is what I heard.

It seems like the days of free hacks are limited, a lot of these guys who have the ability to do all this stuff feel like they deserve to make money one way or another.

Not saying they don't deserve to make money with their skills, just that that's a lot of the reasons many hacks aren't made public. They're either looking for a way to market it, or looking for a buck from the companies for scratching their backs.

Like with my HTC one M8, the dudes behind the exploits that lead to removing all security from HTC devices got together and started charging for the "service". I've seen it in modchips and hardware tools for consoles, but I'm sure many more paid hacks will see the light of day soon.

I recall "Root bounties" where people would donate but then the work would still be released for everyone.

That is the defacto standard for releasing content over at a$$emblergames.

Well in Fail's case, they were just worried about piracy.

how u know that?

 

[FPSRussi4]

how u know that?

Wild guess, but I think it's because he's one of the lead devs in this exploit and knows what he's talking about?

EDIT: I might have a little brown on my nose.

 

[night_hawk]

how u know that?

Simply fof team (the people who made the exploit) said that

kernel exploit will win you the world martial arts tournament, but for IOS you gotta go super saiyan

I thought I read one of them say that. I wonder what update patched it. If someone has a Wii U with a version that is vulnerable then maybe Come would be cool and give it to Marionumber1 or others? Anyone consider this? Or get it to analyze at the very least.
