PD: Cobra Team, came to me defective switch to switch from PC - JIG - DG. You change me?

Can we play games from nas now because it was a new feature in mm a few updates back only for cobra though, now that we have the payload we should be able to get this in a cfw

i hope rogero gets influenced by this to create a new cfw!!! with 431 keys... old packmanager... and the new cobra psp function...

i think sooner or later we will see this on our ps3...

I'm just hoping I can still use this dongle for something in the future instead of holding the door open with it. I'm wondering if I can flash it with Cobras firmware or can I flash it to use as a FSM dongle?

This OpenCobra payload sounds great, lets hope it can work with Rebug or other CFW firmwares.

Agreed, and sadly it's amazing how many people don't catch on to this recurring pattern through the years either

Max Louarn and Paul Owen have Gary Wayne Bowser (aka GaryOPA) plug a product on his Divineo / Xecuter funded domains, cash in on it for several months from unsuspecting PS3 scene users, then it fades to black after an alias (ie NoDRM, etc) mysteriously cracks it and releases patches and so on to make it work without needing to buy their 'disposable' product any longer... ironically just in time for their next endeavor to get underway, rinse and repeat all over (they forget to wash, dirty gits )

Its amazing they have been able to get away with this con job so long, but I guess when they buy up scene devs in the process (ie deank, who to this day denies it only fooling himself LOL ) it ensures they have a constant influx of users to keep their customer base stocked and ready to plug new 'disposable' products again to. Welcome to the PlayStation 3 scene!

who gives a crap about ode ? lol wtf.

this is not worthless... long as rogero or rebug can make a cfw with cobra built-in this will be pretty damn cool.

looking foward to it.

useless to crack it now, because cobra will be releasing ODE and TB was RIP.

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.
