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 = data, 0x38, 1);
_hexdump(" ECDSA R ", 0x38, s->R, 0x14, 1);
_hexdump(" ECDSA S ", 0x4C, s->S, 0x14, 1);
_hexdump(" ECDSA PUB", 0x60, s->pub, 0x28, 1);
_hexdump(" UNK ", 0x88, s->unk, 0x20, 1);
_hexdump(" OMAC ", 0xA8, s->omac, 0x10, 1);
_hexdump(" PADDING ", 0xB8, s->padding, 0x08, 1);
printf("\n");
}

/*!
* \brief Verify section.
* \param s Section.
* \param c Curve.
* \return Verify result.
*/
int verify_section(section_t *s, curve_t *c)
{
u8 hash[0x14];
u8 _R[21] = {0}, _S[21] = {0};

memcpy(_R + 1, s->R, 20);
memcpy(_S + 1, s->S, 20);

sha1(s->data, 0x38, hash);
ecdsa_set_curve(c->p, c->a, c->b, c->N, c->Gx, c->Gy);
ecdsa_set_pub(s->pub);
return ecdsa_verify(hash, _R, _S);
}

//Maybe you're lucky?!
int main()
{
dump_section("0_1", (section_t *)section0_1);
dump_section("0_2", (section_t *)section0_2);
printf("sig. 1 verified: %s\n", verify_section((section_t *)section0_1, (curve_t *)curve0) ? "yay" : "nay");
printf("sig. 2 verified: %s\n", verify_section((section_t *)section0_2, (curve_t *)curve0) ? "yay" : "nay");
printf("R_1 == R_2: %s\n", memcmp(((section_t *)section0_1)->R, ((section_t *)section0_2)->R, 0x14) ? "nay " : "yay ");
getchar();
return 0;
}[/code] 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've downgraded back to MultiMan 4.13 and its so much smoother and faster. All 4.14-16 bring is slower, jumpier and buggier gui. All the problems I've been having recently have been due to the updates. DeanK can you revert the GUI back to how it was prior 4.14 as thats when the bugs started and it started to suck. I only have it on 8.4 and it is so much faster and smoother on 4.13. Go have a try yourself and see how slow and laggy its become.

  • Greatly improved loading content when browsing PS3 HDD/USB drives in game modes
  • Loading Retro ROM/Video/Photo and ISO folders while browsing PS3 HDD/USB is now about 15 times faster
  • Added "Friendly" name option in "Settings"/"Network Servers" for /net_host parties
  • Fixed over-scrolling when browsing through large number of entries
  • Increased max number of entries in game modes by 50% to 3072 (from 2048)
  • The first time you load this version it will take 2-3 seconds longer, but next mM starts will show the GUI in a split second.

The update for CEX/DEX/STEALTH is now available online.

p.s. A big "thanks" goes to all of you who supported multiMAN the last couple of months and before. Thank you!

Also this afternoon I added some more improvements:

  • Improved speed when copying games/files from/to USB HDDs
  • Improved speed when copying games from PS3 Game Discs

I think to play other formats and to play via LAN you need the dongle.

Below is multiMAN version 04.16.02 UPD CEX (20121216) with the changes from deank as follows:

Download: multiMAN v04.16.02 UPD CEX (20121216) (2.57 MB) / multiMAN v04.16.02 UPD CEX (20121216) (Mirror) / multiMAN v04.16.02 UPD CEX (20121216) (Mirror #2) / multiMAN v04.16.02 UPD CEX (20121216) (Mirror #3) / multiMAN v04.16.02 UPD CEX (20121216) (Mirror #4) / v04.16.02 Arabic Language by HAIDER

There is a 04.16.02 version available online (cex/dex/stealth).

  • A show-off version so you can find out what speeds is multiMAN capable of

p.s. You will notice a great performance boost which affects nearly all mM functions (including copy/delete/verify/scanning for games/GUI/loading of images/coverart, faster remote-access, etc).
