The fixed the Nvidia SoC flaw?
Less "fixed" and more "thoroughly mitigated". It's still there, they just changed the boot process of the OS to make it incredibly hard to boot a modded version of it.

If you just want to run Linux or some other non-Horizon OS you can probably still do that.

So basically like fixing a leak by plugging a different hole, interesting.
Following that analogy, it's more like there was two holes. The first one (bootloader) would have a hole itself (the second holehole)whe would flow to give access to the firmware. The first hole is still wide open, but the second one hasn't just been plugged, they replaced the whole damn wall :P

so if they truly patched this issue and the pirates are no longer able to play games that require firmware version 6.2 or higher, will they now have to patch the new games individually to make them run on earlier versions?

Sorry to any legitimate users of homebrew stuff, but I'm glad to see them shutting down piracy on it.

Interesting. I'm a Computer Science major, hence my curiosity. Either way, impressive work on Nintendo's part.

Great news, but I haven't seen anyone answer the question about hackers in online games? Are they still going to around or will it be difficult for them now?

No 6.2 games as of yet, even Pokémon only requires 5.1.
Bypassing firmware requirements is really easy right now. They might have similarly smart solution prepared to prevent that in 6.2 games, however.

same. it would be sad to see the homebrew scene hit a speed bump with this new firmware, but it's best (IMO) to have some way of stopping piracy in the system. just like how vita was recently and after being pretty much dead got hacked wide open, it's better if that happens to switch after a few years, for people to use it as a legacy hardware for homebrew and emulators.

i meant when the games that require 6.2 or 7 eventually come out.
i guess they have to work on that as well, because if not this won't stop piracy in any meaningful way. it's not like pirates are dying to update to newer versions for "stability", if they can keep playing games on older versions.

probably yeah. every new title will definitely force 6.2

smash uses 5.0 key generation and there's a preload version going around so it makes me curious whether nintendo will actually switch it to 6.2 for the actual final release. i doubt it but if they really did it would kill chances of pirates getting their hands on the game.

Very interesting stuff.
I'd be all over a video or text going over all the findings regarding this, what can be figured out about the inner workings and such.

preload means it's already is on people's systems and they'll be able to run it once december 7th gets here, and physical carts are probably already pressed since a while ago. and it's not like they can force an update, whataver version is on the cart and on people's systems will be playable day 1 on 6.1.
so at least the launch version of smash will be pirate-able.

Maybe now that Nintendo fixed their focus on hacking, I hope that they can turn and shift resources towards OS features and online.

But really, great news for them. It's really
impressive.

Impressive patch, will see how long it lasts. This will stop newer games that require FW6.2 and higher from being pirated going forward at least, well for now (until they find a way around it)

At least anyone wanting Homebrew right now can stick on 6.1 or lower, as the state of emulation on Switch is already great.

On one side, I'm glad Nintendo found a way to screw piracy and cheaters. On the other hand, it is sad that homebrew will stall for a while until a new flaw is found.

This eventually being defeated or not isn't really the point. It's more an underscore on how damn good the infosec guys Nintendo has hired are.

Reminder: the kernel and security visor are still 100% bug/exploit free.

Defeating TSEC security now also means it won't be defeated on Mariko as this will absolutely require a burned major exploit. If TSEC can be defeated. We're right now back to using PegaSwitch exploits of all things.

When you remove the exploit on hardware, the secure kernel suddenly becomes a pain in the ass. Doesn't it?

TSEC doesn't just get keys, it's also continually validating the integrity of the RAM - Emunand users are toast too.

Also burns a fuse upon updating.

Good news, hopefully this stops hackers in online games and stops piracy from being so rampant that it hurts third party software support.

That's fine for me, my Switch is on 6.1 and I'm happy to stay there with Retroarch as I have my main Switch for Switch games. Sucks for those that can't buy two devices though.

So for full clarification, this means that someone can't just update their SysNAND and be OK with that with their EmuNAND still on 6.1? Because the 6.2 checks and blown fuse will stop the 6.1 NAND from booting?

You could do this but with a major caveat:

Their sleep mode would be broken doing this, as warmboot checks fuses and will crash every time you sleep.

Pretty cool to see.
I know a lot of people want the Switch to be an emulation machine but I think it's better to have to wait on that.
Since you know people use it to pirate games instead of giving N the money they deserve.

I still have my firmware at pre Kirby version. Would like to buy games on the eshop (octopath and torna) but I've waited long enough as it is for all encompassing cfw.

I could be very mistaken but as far as I understand they basically made it so that the boot chain makes use of a security coprocessor (TSEC) that previously dealt only with other crypto stuff, problem is it's, well, a security coprocessor so hijacking it and grabbing its new secret key isn't going to be easy at all. It, among tons of other validity checks, refuses to do its thing if it notices anything unusual in memory aka patched binaries you'd need to even have booted with the hardware exploit earlier in the chain to begin with. A tough one for sure.
There should be no performance impact though.
If that's an accurate summary then I have to say I'm impressed by the software engineering on Nintendo's part.

Nice!

Kind of bums me out since I was loving the idea of transforming my old switch into something malleable when the inevitable upgrade comes

That said i hardly ever have time to do enthusiast work on a system anymore let alone go back and play old games

Still would be fun to always have the option so I hope hackers find a way back in for the future

Can someone explain why everyone is so hyped for Nintendo to cover this exploit? I don't really play online, was cheating or piracy that rampant an issue? It seems to me like this will just kill the homebrew scene.

Because most people don't care about the homebrew scene, even if they say they do. 99% of users use the exploits for piracy. And that's bad for everyone (well, except for pirates).

It hasn't been rampant just very easy for those who want too. People who take their hacked switches online have been getting regularly banned so cheating has only been a small issue, Nintendo cares a lot more about stopping piracy.

piracy was getting too big. of course the big nintendo games will still sell bucket loads, but smaller third party releases or indie games could use every single copy they can sell, having a system blown wide open and piracy be so easy is not good news for them.
i don't care about homebrew/emulation myself, but i see why some people are interested in that, since switch is so convinent for playing games both handheld and on tv and obviously it'll be a great device to play older games on, but if enabling that comes at the cost of enabling piracy (for a different audience, i mean) then it's best that it gets shut down, at least until much later in the system's life.

Now we can only hope that Gamefreak steps up their game, and Gen 8 has good anti-cheat methods, then we can finally have a cheat free competitive pokemon scene.
