(adsbygoogle = window.adsbygoogle || []).push({}); The famous Geohot resurfaced today, to release a useful app called dePKG. The app is very useful for devs, that are planning to look into Sony's official firmware files. dePKG is a linux app, that will decrypt PKG files, that are within PS3UPDAT.PUP files (not to be confused with PSN PKG files).

This will allow devs to take a look at files such as CORE_OS_PACKAGE.pkg, from the convenience of their PC. Previously, the only way to take a look at these files, was via graf_chokolo's method, which utilized the PS3. Geohot's app is ready to be compiled and includes the necessary decryption keys.

With this, developers can decrypt our own modified .PUP files and encrypt them with the newly found Sony Encryption Keys!

Just to let you know Winky Winky!

So I'm guessing the ps3 gets hacked like the psp, kind of? With the custom FW's?

It works on every PS3 ever made though. Slim, 3.55, 3.40, 1.0, Fat, Japanese PS3, whatever.


Alright this is sweeeeet , do you think they will ever patch?

You simply can't patch this, Sony effed up...Thinking they were boss when in reality their security is ass, I'm surprised it took this long..

It would probably cost a lot of money, because whitelisting everything would be time consuming for them and releasing new hardware I believe would be costly.

It gives everyone, and I mean everyone, on this site a chance to host modded lobbies though. In other words Call of Duty Legitness = Dead...
Except for Black Ops. Just another reason to stop playing the older CoDs and play Black Ops instead(I'm going to save CoD4 though, probably make a patch with only force host and use it all the time). Everyone will be using that damn GSC aimbot in every MW2 game..

Their security is actually very good, in terms of blocking common hacks(stack/buffer overflow) they just REALLY messed up in the cryptography department.

The PS3 had no "Security, it only had encryption and blocking access to the "important" parts of the system, hacking consisted of collecting the decrypted data as it's decrypted during bootup, or launching the files/programs, that's where the real hacking came through

In reality, it didn't take very long, nobody had a reason to hack the ps3 when OtherOS was still available

But, sony really ****ed up and took it out, expect to see the PS4, coming very soon :carling:

I'm no dev so I have NO IDEA what the hell I was doing when I was looking in the CORE_OS_PACKAGE.pkg

ALL CREDIT FOR THE EXTRACTOR GOES TO A GUY CALLED "Ac K"

This (the private keys, not the tool) allows you to do whatever you want on the PS3. Any code you want signed, say an FTP server, can be signed and will function a retail PS3 with 0 modifications. The PS3 will accept it as if it was from Sony.

This has absolutely nothing to do with the jailbreak at all.
And the PS3 still can't run unsigned code without a jailbreak, but now it doesn't need to run unsigned code.

Anyways about this tool, it doesn't work for Retail PKGs(so don't think that you are getting a challenge lobby with this). It works with Firmware PKGs, like CORE_OS_PACKAGE.PKG or BLUETOOTH_FIRMWARE.PKG
People can now begin looking more deeply on how the firmware functions.

hey did you find someone to test what you asked the other night with taking out the sfo file i still havent found battiers for my calculator lol
