Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
110w ago - Following up on the PS3UserCheat and True Blue unnecessary DRM-infected dongles being hacked alongside zadow28's work, today PlayStation 3 developer oct0xor shared a video of his OpenCobra Payload which aims to render the current Cobra USB dongle from Max Louarn useless.

Below are the details from his [Register or Login to view links], as follows: "First I am going to say that this is not going to be an article, just a first blog post and some info about my recent project.

Finally I got my hands on cobra it was quite a lot of time since I touched this last time. There was s good things happened since then eg. I reverse engineered usercheat and true blue, had done a lot ps3 and not ps3 related hacking. There was a bad things eg. BlueDiskCFW, lv0 leak, a lot of devs leave the scene...

Cobra was for me really "the last" thing I have to do.

The last time when I worked on this I didnt had a dongle, and all what I had was a dump by JaiCraB. I reverse engineered it as much as possible, figure out almost all tricks, encrypton and etc. And figuare out that it reads a lot of data from dongle, and I cant do much without dongle itself. Thats why I put this project to the back burner.

Well... I had never buyed anyone dongle, and I never was not going to. All my dongles was donated (thanks again ) but not that time.

it was hard for me to make this decision but a few days ago cobra finally shipped to me...

3 days and now its all over.

Security is good enough, but not without big security risks. But it still the best crypto/obfuscation what I had seen on ps3. Sony have something to learn from this guys, especially now.

Cobra / True Blue almost identical, have the same source code, if you ever hacked 1 thing, 2nd wouldnt be a problem. The main functionality, honestly, not changed since original jb. Thats a shame. Thats why I cracking them like nuts





On the fourth day I taked a decision to make my own "OpenCobra" payload. only clean code without drm and garbage, to be able to port it to any new firmware, and change/add features. It taked 2 days, 3000 lines of asm, and you had seen the result.

Atm it based on 4.1 payload, plans for future is check/add new features from 4.4/5.0. Port to a new firmware (if cobra will not do this for me), and realize all nice innovations from new version of psp emu, such as better emu accuracy, 3D and etc...

In video you had seen Payload Loader. Thats the all code it has:

This tag related patches handled by mngr. So far I want to move it in payload. First I have to check how it handled in 4.4 / 5.0

Not sure yet when it will be released, if it will be, but we will see.

Keys!

If this subject will be interested for people, maybe I will write a full article about True Blue / Cobra analysis and hacking.

btw: Me and ~ some psp mysterious dark figure ~ reverse engineered algo for generating valid psp isos back to jule. But saves and a lot of games dont work without patching. So cobra's patched emu much better there imho."

Below are some additional pics from his blog which simply states: Usercheat + Cobra = <3

From flat_z: Here is some explanations to make things more clearer. If you read my twit about ps2_netemu you can see that I reverse-engineered it. It includes almost all things which are required to make custom disc images of original PS2 discs and run them on the PS3 if everything will works fine. So it can lead us to the process of remastering PS2 discs which includes making of ISO.BIN.ENC (the encrypted version of original image which can be read by the PS3), creation and encryption of .VME files (virtual memory cards), ISO.BIN.EDAT (includes the title ID of disc).

The only thing which is not currently known is the format of decrypted CONFIG file (I can decrypt the file and encrypt it back but it have a complex format). It is optional and can be empty but I'm afraid that some games requires it to run on the PS3. My plan was the creation of PS2 remastering tool and I wanted to share it. Although I even not sure will it work or no but there are many chances that it will.

But something happened before I started to do it. My HDD on the laptop died and I have all information regarding PS3 on it. Although I was able to restore some important files but not all. So I need a time to buy components for a new computer and build it. For the same reason, I have a delay on my real job (I'm working as a free-lancer) so I will going to do my job before I start to do something new for PS3.

P.S. I see many questions about compatibility. You don't need a backward compatible PS3 console to run PS2 games through ps2_netemu because it is software emulator and doesn't require any PS2 hardware components. Also I think that ps2_netemu is more better and stable than ps2_softemu but this statement requires testing.

Finally, from naehrwert (via twitter.com/naehrwert) comes some related Cobra ODE EID0 information (ECDSA from pastie.org/6169158) , as follows:

While this is definitely interesting news, odds are it's just a ploy for the Cobra Team to release a new dongle that will be 'required' for their upcoming PS3 4.3x CFW unfortunately or the PS3 ODE in order to further line their pockets with PlayStation 3 sceners' hard-earned cash once again... as always, time will tell for sure.

Got a spare ps3 i was able to jailbreak and is now running 4.66 darknet cfw.

I have had IRISMAN on it and it has picked up my ntfs drive no problem and found my backup iso's on it. Although some of them were not showing up even though converted and checked with IRD files etc changed file names and still not picked up by irisman.

So i thought i would try multiman as i want to use the same external drive for my other console which has a cobra ode installed. I cannot get it to detect the drive on the multiman xmb but if i go into mmos file explorer it see's the drive.

I have put iso's in 'GAMES' & 'GAMEZ' on the root of the drive and it will not detect them.

Have i got the folder system wrong?
At the moment it is:
Root:GAMES\GAME.ISO
Should it be:
Root:GAMES\GAMENAME\GAME.ISO
??

Or if anyone knows why irisman is not detecting some of my backups, ff13 lightning returns and need for speed rivals are 2 of the ones not working but they are detected and play fine on my cobra machine.

Also, everytime I reinstall multiman via mmOS and opening report_data.txt (renamed to report_data.self) from MM4.66.06, it turns bd-emulator to enable until I choose one game. I can play the game for half an hour or so before it sends me back to XMB and If I check Multiman again, bd-emulator is back to NONE and UNAVAILABLE.

change to normal cfw
