Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
115w 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.

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.

the only thing you'd really want the dongle for is to play your legally owned ps2 backups, well that's what i'd get it for anyway. otherwise, multiman and kmeaw is just as good!

Surely he 's using it without dongle. Guys, please, wake up. Without dongle, doesn't do nothing more than what old version always did plus a lil more tricks..

I cant really help much with that as im on Rebug 3.55. Some more info might help others figure it out, I assume you are using the new cmMM 4.00?

Do you have the Cobra dongle? does it happen EVERY time you exit MM or only with certain games mounted etc?

The way I see it, even if he did "sell out", at least this version of multiman works without the dongle so you can use it on kmeaw. To me that sounds more like the case of "this is the free version but with the pro you get these features", which, I'm perfectly fine with.

Open Office is only one of many open source projects. It in itself is the combination of many other open source projects. There's literally millions of open source projects out there.

I don't fault deank if he decided to profit off Multiman. As far as I know, he contributed the vast majority of work to the project. If he solicited the help of others under the guise of open source and then turned around and sold it for a profit, then I'd have a different opinion, but as far as I know that is not the case. Would I prefer he continued with a free open source development? Of course.

Also, it's worth nothing that deank has denied allegations that he's working with Cobra. His past actions have given me no reason to believe he's anything but trustworthy. I agree the sudden stop of development appears suspicious, but there's many possible scenarios.

Maybe it's all coincidence and other factors in his personal life have stopped development. Unless you know deank personally, I don't think anyone has a right to doubt his claims. I can imagine many scenarios that he might not want to share with everyone (eg. cancer, dead relative, unemployed, etc) and it'd be terrible if people were giving him a bad name over purely circumstantial evidence.

I'm grateful for his past contribution as I know I'm entitled to nothing.

I have said that they both dongles are doing the same. But for me guys like grafchokolo have done much more then those both teams. All the files used on this both sticks are frm dev_flash and just patched/ported and not rewritten or anything else.

But anyway it seems you haven't understood. tHeUnknOwEnSeCRet will do this all for acid cfw and even don't want fame. He only do this for helping peoples and he do this for acid cause we share the same ideology about those things.

Or some other teams, like exetrimall

You seem fairly sure the way you say "HE IS", Any actual real proof of Dean's involvment or is it just Team Ac1ds personal opinion?

BTW: love the GUI's in multiman, really smooth. its really come on in the last year. Anyone seen the way the glitter in screensaver moves with the Sixaxis angle? its neat!

I think DUPLEX are the answer to all these problems, just wait for the DUPLEX release, that's what I do and I don't mind waiting a little longer for the latest games.

Actually it doesn't say that it requires the dongle at all for anything. It says it will work without the dongle. So I guess I'll be the only one that will test it.

The thing that makes less sense is how would it work if without the dongle the system thinks its on ofw?? So how would a homebrew app like MM work? lol
