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.

  • Split files format: .0 - .63 / .66600 - .66663 / .001 - .064
  • Supports both "PSN (Bubble)" and "Standard" install methods

Update: [Register or Login to view links] (2.44 MB) / [Register or Login to view links] (Mirror)

Here it is - please test and report back. It should allow for any number of NTFS partitions if properly set in USB.CFG (otherwise 2 partitons only). It should allow detecting multiple hdds with same vendor/device ids (for resetting usb bus).

The issue is that mM can't reconnect them in the proper order because both have the same IDs and it can't distinguish them. Your only workaround is to connect only the drive you want to play from. Do you see both drives disconnect/reconnect when doing the usb bus reset (if they have lights and are unpowered you can see).

It is not related to multiMAN. Last week I tried to replace the libusbd.sprx, libio.sprx and other .sprx files - I used these from 3.55 and replaced the ones on 4.21 with ABSOLUTELY no result... I got the same issue so it must be something else.

After a lot of tests my final conclusion was that the drive connect order is what's important. When the PS3 boots it usually initializes /dev_usb000 first and that's why games from it work if you don't touch anything. The solution for now is:

1) Disconnect all drives
2) Connect the drive which has the game
3) Connect the remaining drives

The connect/disconnect is only possible by specifying the vendor/device IDs and as in your case - both disconnect and both reconnect at the same time which breaks the procedure. If it was working properly they'll be reconnected with 5 seconds delay from each.

Sorry for being outdated on the PS3 scene developments, but i'm just back home after several months and only now switching on my fat PS3.

Yes as long as you use the CEX version you should be fine i have the same 3.55 kmeaw you have and i am currently running multiman 4.12 hope this helps

2 sharks: use the CEX version (this is for normal console), DEX is for Debug / test consoles.

Changelog: mM 04.14.00

Changes related only to 4.20-4.30 CEX/DEX CFWs:

BD-Mirror:

  • BD-Mirror option now supports USB HDDs mounted as /dev_usb000 to /dev_usb127
  • BD-Mirror option uses different approach now and doesn't move the PS3_GAME folder of USB games and doesn't modify the mount table
  • After using BD-Mirror for USB games, the usb drive is still accessible in XMB (Video/Music/Photo/Saves)
  • Improved disc-less support with BD-Mirror option enabled

USB Ports issues:

  • When using more than one USB device mM will disconnect/reconnect them from/to the USB bus in the proper order
  • This fixes games that crash when started from USB when multiple devices are connected

NTFS/PFS usage:

  • It is now possible to use any NTFS usb drive without configuring its Vendor/Device IDs in USB.CFG
  • When switching to NTFS/PFS mode use only one USB HDD connected (mM supports up to 2 partitions: FAT32+NTFS, NTFS+NTFS, FAT32+FAT32)
  • To access the contents of NTFS drives use mmOS and /pvd_usb000 /pvd_usb001 (games from NTFS drives won't show in other display modes)

Other:

  • Better support for data CD/DVD/BD discs and improved "Enable Direct Disc Access" function
  • Improved BD-Mirror function for games on internal HDD
  • Games started from mmOS icons/shortcuts handle BD-Mirror/Ext.Game Data options properly
  • Online update server updated (5320 PS3 game covers and 3420 PS1/PS2 game covers)
  • Updated showTIME media player (for mM) to version 04.01.264
  • Updated 8 translation files

Install Package Files (standalone application):

  • Supports split pkg files named in the following format: filename.pkg.0 -> filename.pkg.63, filename.pkg.001 -> filename.pkg.064, filename.pkg.66600 -> filename.pkg.66663
  • Upon launch/refresh the following folders are scanned: /dev_usb***/, /dev_usb***/PKG, /dev_usb***/packages, /dev_hdd0/PKG, /dev_hdd0/packages
  • Updated stDISC application (better drive reset timing and support for 4.30CFW)
  • Updated gameDATA, bdRESET and lastGAME applications to support 4.30CFW
  • Updated showTIME media player (standalone) to version 04.01.264 (CEX/DEX)

The showtime version provided with mM as standalone acts as the build-in one so it returns to mM. If you wish to quit to XMB either use the official build or use {PS} button -> Quit to XMB.

About NTFS - if you previously configured usb.cfg just stick to it. Without USB.CFG only two partitions will be available - that's it.
