Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
114w 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 blog, 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.

For those who own one, Cobra USB Firmware 3.2 and 3.3 are now released with the following changes: 05 - 09 - 2011

Cobra Firmware v3.2 More Features and bugs fixed:

  • Added support for PS2 backups in optical discs (CD-R/DVD+-R)
  • PS2 original games are now region free too.
  • Fixed a bug that caused incompatibility with several PS2 backups in iso format.
  • Fixed some remaining PAL/NTSC problems in PSX games.
  • Cobra USB Manager will output now a mds file too when dumping a dual layer DVD or PS2-DVD. This file is not used by Cobra at all, but it can be used for burning to a dual layer DVD+-R while keeping original layer structure. This is mandatory when burning dual layer PS2 dvd's.

Cobra Firmware v3.3

  • Fixed a bug introduced in 3.2 that made some systems unstable when starting a PSX game.

I would buy this if JFW wasn't being made.

They must have some real talent onboard their team, considering the features they have with it, and the water tight security (so far) on the device. I'm also very surprised that it hasn't been cloned yet as its been ages.

Maybe everybody waiting for the jailcrab-dh firmware and maybe no one moved to clone it.

I understand it's supposed to have some sort of on-board security, but since when has that stopped anyone

For those who own one, Cobra USB Firmware 3.1 is now released with the following changes:

Cobra Firmware 3.1 is out, minor release to fix bugs.

  • Fixed stability problems. Cobra users are advised to update to this firmware as soon as possible.
  • Fixed compatibility issue with Mortal Kombat.
  • Fixed PAL/NTSC issues in psx games.
  • Bugfix: some few specific psx titles such as Langrisser Final Edition wouldn't play in other regions.
  • Fixed a possible discless bug under very rare circumstances.
  • Cobra USB Manager can now understand the ".001, .002, ..." name convention used by hjsplit and other similar programs and rename them automatically to ".0, .1", name convention. Users can use hjsplit or any other similar tool to split iso files in the PC.

As far as I know every PS3 model is capable of PSone emulation but not every model is PS2 backwards compatible.

Cobra USB however can enable PS2 emulation on every PS3.

Here is an update for Cobra USB users by johnnydoe of the Cobra USB v3.55 patched with Kmeaw features: ps3crunch.net/forum/threads/355-Cobra?p=3474#post3474

To quote: Hi everyone! i have patched the cobra firmware with the usual stuff like lv2 peek/poke etc both their core os files are patched so it should work with or without the dongle.

If you wanna unpack it and have a look or try it you can download it here: http://www.multiupload.com/3B1XM6OUCE

From the ReadMe file: This is cobras 3.55 firmware patched with peak/poke for lv2 on both coreos files and the usual vsh/nas_plugin and install package file option.

Finally, confirmed by PS3 hacker Cyberskunk stating there: It is what it says it is but you would still need the dongle to use the cobra features. I have not installed it though..

I'm confused about this part. "Integrated support to play PS1 game ISO’s from HDD". Would this mean for backwards compatible PS3's on 3.55? I have one of the newer slims sadly lol.

Today the Cobra USB 3.0 Firmware Pack and 3.55 PS3 CFW is released, with details below from their site:

Download: Cobra USB PS3 CFW 3.55


The Cobra Team is proud to present the Cobra 3.0 firmware pack, available from downloads section. In this release we enabled the Cobra USB device on 3.55 via use of our own cfw. Enjoy the release and look forward to many new features to come in future releases. Please be sure to read the updated user manual for detailed instructions on upgrading and usage!

  • Added compatibility with 3.55. Support for firmware 3.41 is discontinued, since now all updates will be for 3.55. In 3.55, Cobra keeps all the features of previous versions, adds the ones listed below and also removes some of the annoyances of the jailbreak exploit. Please, follow the steps in the manual, you must install first Cobra 3.55 cfw.

  • Added a new discless mode for PS3 backups in jailbreak format. This mode will be activated automatically when you load a backup and there is no disc inserted. In this mode, games are loaded from disc icon, not app_home, although app_home hack is still supported. This mode has a higher compatibility than the app_home hack, and smaller than discless PS3 isos.

  • Added support for PS2 backups in iso format to the remaining backwards compatible models (CECHA and CECHB).

  • PS2 isos can now be played discless too.

  • Fixed compatibility issue with GT5. If you still experience poroblems, please delete installed game data from XMB and try again.

Note: Cobra CFW will behave like a 3.55 ofw if the PS3 is booted without Cobra USB connected. It is useless to install this CFW if you don’t have a Cobra USB device.

Cobra USB requires certain binary files of the firmware not to be changed. Changing these files may make Cobra USB not to work at all, or to behave incorrectly. Changing fonts, xml, etc is fine, if the user knows what he is doing.
