Can someone explain what are the consequences of this? Can this be patched? Does this mean cracking games will be possible?

If you disconnect your PS5 from the internet now, then yes, probably, in a few years. I would anticipate Sony using updates and e-fuses to prevent its use on any console that stays live.

From the thread:

We might get lucky.

I'd be surprised. The PS3's keys were leaked too (by the same group, in fact), and Sony managed to put the genie back in the bottle in a pretty amazing way.

Is there any reference to how Sony re-secured the PS3? All I'm aware of is the fact that they killed the ability to run Linux on PS3 because they couldn't re-secure it while retaining the ability to run a different OS.

Wait, wasn’t it the other way around? There was that fail0verflow slide about how the PS3 took unusually long to crack if you count from the release, but essentially the same time as other consoles if you count from the moment one couldn’t run other OSes on it.

If it was cracked after Linux was removed, then what was the reason for removing Linux? My recollection was that it was a security vulnerability.

They started out by not including it in the Slim, then removed it for "security reasons" in a firmware update for the original consoles. I imagine they just decided not to bother with the new product, and then wiped it from the existing ones.

Some people started buying ps3 to build compute clusters.

This was because the ps3 had a very strong processor made by ibm, using rhe powerpc isa.

This meant that ibm started losing sales of their powerpc systems.

So the story i know is that ibm "asked" sony to stop allowing linux on the ps3.

I don't remember the specifics, but after the keys were leaked (this would have been about a year after OtherOS was removed?), Sony managed to both release a firmware update that disabled homebrew, as well as block new releases from running on the old, hackable firmware.

That new firmware lasted for more than a year, too.

But wouldn't this allow to decrypt any future patch data and see exactly what was changed, thus allowing to bypass it?
