(adsbygoogle = window.adsbygoogle || []).push({}); Hello. A few days ago some1 reported this news via graf_chokolo that had successfully Understanding these multiple files .Self important. Well, today he released a payload that allows the decryption of file .Self, now anyone can decrypt the files .Self.

So what does this mean for the average user? The developers as can now see the contents of the executable system and those games. The review of these files may also lead to the discovery of new exploits, which could lead to a jailbreak see beyond 3.50.

You will understand, this payload is intended primarily for developers, so if you knew nothing about it do not try anything on your console and wait politely.

Of course this can help us for hack BO, but someone has to know how to use this payload. So if anyone know how to use it can help me and noob like me making a tutorial :mad: .

If u think this could be useful Rep+ !!! :p

This was stated by him to not work for games.

read the post he made it works for games to

Guys, i promised to you to make my SELF decrypter public. I just uploaded it :-) Let me first explain how it works.

I used only HV calls in my code because i wanted to learn how to decrypt SELFs without GameOS. The decryption and decompression of SELFs is done by isolated module appldr which is prepared and loaded by lv1_undocumented_function_99. After appldr is loaded it sends a message and waits for your instructions to decrypt some encrypted segments. When the message arrives i pass encrypted segment data to appldr through shared memory and it decrypts the passed data. When the decryption is done the payload sends the decrypted data over network to my PC and i capture it with tcpdump :-)

I’m using IDA to analyze the decrypted code. First i extract the decrypted segments from pcap dump and load them at right addresses into IDA. I created a shell script to make segment extraction from pcap dumps easier. Virtual addresses of decrypted segments you will find in ELF header.

The target group of this release are again advanced programers among you. The goal of this release is not to give you a tool for SELF decryption but to show you how it can be done :-) So, feel free to ask me any questions about my code. I will support everyone who wants to port my code and create more user-friendly GameOS applications for SELF decryption because i do not intend to write any GameOS tools :-) I’m more interested in HV reversing :-)

My SELF decrypter is not able to decrypt games and NPDRMs yet but i’m working on it :-) I think you will have enough SELFs now to reverse :-)

Look at my post above.. no it doesn't work for games.

Copy and paste from PS3hacks:

Just the other day we told you about graf_chokolo decrypting SELF binaries; however, NPDRMs and commercial games could not be decrypted … that is until now! It would seem graf_chokolo has pulled through and is able to do just that.

I will make my findings public very soon

Here is a snippet of a game i decrypted: #1347337 – Pastie

What does this mean? It’s likely graf has found the master key and we can now work on hacking
and patching whatever necessary to get 3.50+ required games running on lower firmwares. The PS3
master key, for real? For real. It’s all here — follow the comments in this post.

Exactly, enough said.

But when Graf first released it, it couldn't decrypt anything Related to the game os, and from what rumor has it, Sony is going notorious and might remove Game OS from the Firmware so that newer games can't have game files decrypted and modded. But like I said I heard it through the grape vine. Not to sure its its true, but lord knows Sony is Sony so they can do what they want to do.

Nice PLAYSTATION HACK...

This has absolutely nothing to do with ANY game
