Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
92w 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.

I think that he only implemented the usage of the psp/ps1 emulator and doesn't try to improve the hole thing.

Also we get no information on that kind meaning why this or that don't work. Looks like he still try to put a mass of things into the app without thinking on other things.

Hi cfwprophet, I see your back around. this is multiman for Cobra, this means it is not just deans work so he can't be held 100% responsible for it.

I think honestly dean is doing a great job with multiman and its just sour grapes. Are we talking about same application/coder?

I think his app is one of the best with the best features, and has some of the best after support around. I do not see loads of threads about any serious errors it has caused so i'm not sure why there is negativity on here towards dean.

Maybe he doesn't know these things, maybe he does know and doesn't want to share, I certainly won't be dissing him because of info he may or may not know or info he chooses to keep to himself for whatever reason he might choose. That is his right.

P.S. Have you seen all the improvments he has made to ps1 emulator hack since it came out? And you think he doesnt try to improve things, if that were true we would still be using multiman0001!!

anyway I'm sure if you know about some solution -offset thing to add- that will make these patched ISOs work i'm sure dean will implement it if you can explain a little more, What is this patch to these ISOs that make them different than normal ISOs, I haven't heard about them, maybe dean hasn't either?

Well they still need to get PSP .ISO files fully working, other than that there are really no flaws.

To quote from their page: 03 - 01 - 2012

Update of Cobra USB firmware, Cobra PSP Launcher and mmCM focused on improving the compatibility of the psp emulator.

Changelog of Cobra USB 4.4 and Cobra PSP Launcher 2.0:

  • Added specific support for the following 15 psp games that either crashed or had critical gameplay issues:

BLAZBLUE CONTINUUM SHIFT II
DJMAX PORTABLE 3
EXIT
Fate/EXTRA
LEGO Pirates of the Caribbean The Video Game
LUNAR: SILVER STAR HARMONY
Resistance: Retribution
SMT: Persona 2: Innocent Sin
SOULCALIBUR: Broken Destiny
STAR OCEAN: First Departure
TEKKEN 6 (fixed random crashes)
The 3rd Birthday ((if you see a black screen at beginning, press buttons, it will work after that)
VALHALLAKNIGHTS
White Knight Chronicles: Origins
Z.H.P.: Unlosing Ranger VS Darkdeath Evilman

  • Added support to load prometheus patched psp isos.
  • Added an option for psp emulation. You can set it per game in multiman using "Game settings".

You can choose between auto, mode 1 and mode 2. By default, all games are set to auto, what causes mmCM to choose the apropiated setting from a database, but you can set the option manually.

Mode 1 and Mode 2 have different compatibility, some games that work in one of them won't work in the other one. Mode 2 is usually more compatible.

Changelog of mmCM 03.01.02:

  • Added support for three different modes to load PSP ISO files (Auto, Mode 1, Mode 2): "Game Settings" in XMMB/XBDM SIDE menu
  • Added support for lastGAME application - it will load the last game you played, without entering mmCM
  • lastGAME: Application which loads the last played PS1/PS2/PS3/PSP game (folder and ISO format) (separate application)
  • bdRESET : Application which resets all redirections and unmounts loaded ISO images (separate application)
  • Note: When you use "Last Played Game" application you will have to launch the PS1/PS2/PS3 game from the disc icon and the PSP game from the "PSP Launcher" icon

Related news from the Cobra Team: 05 - 01 - 2012

About the problems some users are having in 4.4... Some users have notified us that after update to cobra 4.4, their system freezes when starting the system with cobra inserted. In cobra 4.4, some internal changes were made, and cobra 4.4 is not longer compatible with some modified system files.

Users that have this issue likely flashed some unsupported modules in the system, either by themselves or done automatically by some program. In addition to cobra CFW 3.55 modules, Cobra firmware 4.4 officially give supports to the following commonly used modifications:

  • the modifications done by bitsbubba in bitsbubba NFW v3
  • replacement of vsh.self by reactpsn 2.0 one (only the one in the 3.55k folder)

Any other alteration to system modules may cause a hang since cobra 4.4. To fix this problem, access recovery menu in the ps3, without cobra inserted, and reflash Cobra USB CFW or the modificied CFW by bitsbubba NFW v3.

If you wish that we give support to some more modified modules, send us a message about it and we'll give support to them in next version.
