Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
88w 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.

We're getting there... But don't pay for a dongle, with patience all comes free...

And then there will be PS4 and we started over again...

Today we have a little snipesd of the COBRA dongle with a few interesting parts of code they proof that what we sayed is true and that you can turn a normall retail ps3 into a debugger one or at least into debugger mode. Enyoi reading and have fun



flags -> 0x8x

-> load /apphome/liblv2.sprx

/devflash/sys/external/libv2.sprx

sys process elf

sys prx user

sys prx kernel

elf fixed

it's a patch !!

real time patch

elf -> LV2



and after they said that cobra/tb2 are not related to debugger

Version -> 0x08X the PS3

revision -> boot mode



selfdecrypter ??


hmmm


kernel memory shrinked ? there is the part emulator etc
/apph@.ome...../devusb0D.00...........D.|...d......P..... ..r....t.`...,....

That new display mode looks awesome, it's simple and easy to use. I'm also glad they added new themes, the ones that came with the first mmCM weren't that good.

Below is a mmCM (multiMAN Cobra Manager) v04.00.01 Base (20120126) update for those with the dongle, with the changes outlined as follows:

Download: [Register or Login to view links]

26 - 01 - 2012

  • Added new display mode (Board 5x4x5), replacing the oldest "Game list (plain)" mode

  • "Board" display mode shows ICON0.PNG game images by default. You can use covers by changing the option "XMMB Icon Swap" in Settings

  • Improved File Manager visuals when used in SD resolution (480p/576p)

  • Fixed an issue, which prevented operation on CFW/MFW 3.41

  • Added support for showing PSN titles in all display modes from internal/external HDD (PSN titles cannot be loaded and you have to put empty RELOAD.SELF in game's USRDIR folder to make it show!) (requested)

  • Added lastGAME2 and bdRESET applications

  • Added 11 new themes to the theme download section (total of 14 now)

  • Updated 15 language files

  • Added separate background images for Board and XBDM display modes (PSVBG.JPG and XBDBG.JPG)

  • Updated mmCM Original Theme (includes new images PSVBG.JPG, XBDBG.JPG, PBOX0.PNG, PBOX1.PNG)

  • Preparations to support loading of network PS3, DVD and Blu-ray ISO files

  • Preparations to support firmware version spoofer (auto-spoofing to latest official FW or to user-defined fixed version)

  • Required Cobra USB update will be announced when network ISO and firmware spoof support is available

Q: So what's the advantage of lastGAME2 over the original LastGame app?

A: There are 3 versions actually:

1) The original lastGAME works with mM 01.13.* - 02.09.02.
2) lastGAME2 works with mM 04.00.00+.
3) lastGAME2 for CobraUSB works with ISOs (DVD/PSX/PS1/PS2/PSP/PS3/BD-movies), too.

There is no way to play PSP games without it unless it is a PSP Mini game from PSN that works on CFW (someone correct me if I'm wrong). PSP games are mountable on the PS3 though ([Register or Login to view links]).
