another clone? -> FAKE!

File:Infinitydongle.jpg

This clone turned to be fake and Matrix team was not involved.
To quote:
Matrix Team, producer of popular products suchs as Matrix Infinity, Matrix Glitcher Series, Matrix Freedom PCB etc. would like to clearly state we are not involved in any way in the announced ‘Infinity Dongle’ for Playstation 3. If this product is not a fake the people behind it are clearly trying to profit from Matrix Team excellent reputation in both production quality and product support to improve their sales.

Thanks to oct0xor we could get our hands on the decrypted TB payload (stage 2). Of course the first thing to do is to fire it up in IDA, our favourite tool of the trade. The entry code of the payload looks like this:

1337C0DE00000000 _start:

1337C0DE00000088         bl        payload_main

In the first loop it will relocate itself using 0x1337C0DE as an identifier for the upper 32 bits and rewrite that to the actual base. The disassembly above was already loaded using 0x1337C0DE00000000 as base. While scrolling through the data section at the end of the payload one quickly figures out that the RTOC is 0x1337C0DE00017E40.

As I was analyzing the code I found a sub that was basically just a really big switch with random looking case values. Once I reversed the sub at 0x1337C0DE00002578 and some of the following ones and analyzed their usage in the switch sub, I knew that I was looking at a fricking virtual machine.

1337C0DE00002578 vm_push_word_0:
1337C0DE00002578         ld        r11, off_1337C0DE00010128 # stack_ptr
1337C0DE0000257C         ld        r9, 0(r11)
1337C0DE00002580         addi      r0, r9, 4
1337C0DE00002584         std       r0, 0(r11)
1337C0DE00002588         stw       r3, 4(r9)
1337C0DE0000258C         blr

Paranoid TB developers even used XOR-tables to obfuscate the VM instructions and data. The virtual machine is mostly stack based but the instructions let you work using registers too. The next thing to do is to reverse all the instructions and write a disassembler and emulator. Here is some code to unscramble the embeded vm binary for further investigation. I’m going to write more about this topic in the future.

Q&A

Q: Is this posible on other dongles from the FW3.41 days like Blackcat and Teensy?
A: Dongles are bad and obsolete, mkay :P (once you have the key/algo, you don't need any dongle at all)

Q: Are they (TB team) just stealing the dev eboots?
A: You can only rumor which source they use to resign the content to lock-in their DRM. But ofcourse those very same DRM-less files can be resigned for 3.55 too (as has been done numerous times in the past). Piracy is bad, but pirates using DRM to make sure they get the money and not genuine developpers is even worse (especially when they lock you into a single firmware that has even less to offer than generic MFW and makes you loose OtherOS++ too).

Q: Is it possible that they (TB team) have an FPGA setup to read the PS3's RAM, upgraded the PS3 to the latest FW and dumped the RAM after the PS3 loads a game. Then extracting decrypted EBOOT.BIN from the RAM dump?

00:33:35 <McLamer> sounds great :-)
00:33:43 <McLamer> for what is the updater ?
00:35:37 <openTB> EBOOT.BIN.elf , EBOOT.bin ,, on dongle-updater.pkg.out

Fake proof:

  1. Though the 2.3 payload upon execution does relocate itself to 0x80000000007f0000 then continue execution, the USB descriptor is still present, at minimum those 0x20 bytes would need to be removed, or accounted for during the initial execute. multiMan has no facility for this.
  2. The initial EBOOT.BIN.elf does contain the 2MB flash contents for the dongle, BUT that would need to be carefully extracted (and has been, it too is available on the ps3devwiki), again multiMan has no facility for this.
  3. The creating of the folder and copying the files into it was just to make this fake seem more real with additional steps. multiMan has no code to ever look inside that directory.
  4. The fact of the matter is that the source code for multiMan was available, and there is NO provisioning in multiMan for "additional" payloads of any kind, the values possible in the .ini file are hard-coded. It is well documented what payloads work with multiMan, and multiMan will only work with those payloads.

You have as much chance loading Windows 9 on the PS3 by using ntldr as payload renamed...

stupid newssites

For some reason newssites ([1]/[2] like to be trolled or troll themselves (maybe because they profit from selling these IP-stealing reDRM dongles):

How to use it:
If you attend to downgrade 3.56+ console and use TB dongle after that then 
use this steps (if you already at Rogero CFW V2.0 do the same steps also):
- Dump your NOR flash using Progskeet first if you didn't have a good dump from your console.
- Download patch file attached to this thread.
- Extract this file and you will get 4 folders use patch in folder "Coba_2" to patch your dump using WinSkeet.
- Apply this patch to your dump then flash it to your console.
- Enter a Factory Service Mode using any method you like.
- Use TB CFW with Lv2diag.self to flash your TB CFW in FSM.
- Start your console normally, if it brick just dump this NOR flash again then patch again using "Coba_2" patch.
- If it still bricked use "Coba_3" patch to patch your dump again then flash it back to your console.
- Start console normally, now your console can run TB CFW on downgraded console.
- Power off your console, plug your TB Dongle then power it on again and enjoy . 

Credit goes to Kado for this patch
Also a very big thanks goes to:
Abkarino (Me kado gives me this not me),nice69, uf6667, rogero,muggi, eusnl, ago, and all ppl.

Hot Tip:
For every one interested just look at patch2 file it is and empty coreos file with only part of lv0 modified to do this trick 

There are many wrongs in above statements:

  • It is not related to TrueBlue/Cobra, but to installing unmodified (no downgrader patched lv1.self) firmwares on downgraded consoles (which thus have syscon hashes at 3.56+)
  • There is no lv0 modified in the patch files, the data still there is just author lazyness
  • It can be done so much simpler by just using 3 files and even less stages (mentioned on Downgrader talkpage)
<eussNL> kado ?? <eussNL> ROS empty until 366770 <Abkarino> yea, this is what kado said to me : this is an offset for a modified lv0
<kado> eussNL: yes thats not lv0, thats lv2kernel took from rogero 
<eussNL> ok, so leftover from FSM
<kado> yup
<eussNL> in that case I was correct in my assumption "<eussNL> btw the unreferenced ros area is not lv0, but leftover from lv2_kernel.self"

So much for the trial to make the world believe the lie that they pwned lv0 ;)

old talk

(seems obsolete and incorrect in many ways)

It seems the ps3jb2 loads masterdiscs with fself, with the algo provided and the right key (which is not provided) you can decrypt said masterdiscs images right on pc and grab the fself files.


   // do crypt
   unsigned char sector_key[16];
   memset(sector_key, 0, 16);
   sector_key[12] = (sector_num & 0xFF000000)>>24;
   sector_key[13] = (sector_num & 0x00FF0000)>>16;
   sector_key[14] = (sector_num & 0x0000FF00)>> 8;
   sector_key[15] = (sector_num & 0x000000FF)>> 0;
   
   // encrypt sector
   aes_context aes_ctx;
   aes_setkey_enc(&aes_ctx, G_DEBUG_KEY, 128);
   aes_crypt_cbc(&aes_ctx, AES_ENCRYPT, aligned_size, sector_key, buff, buff);
   
   // decrypt
   aes_context aes_ctx;
   aes_setkey_dec(&aes_ctx, G_DEBUG_KEY, 128);
   aes_crypt_cbc(&aes_ctx, AES_DECRYPT, aligned_size, sector_key, buff, buff);

that's the algo for masterdiscs
ps3gen dll has the static keys for masterdiscs
you can also get it from sv_iso
the crappy sdk tool that generates masterdisc images for dex


more talk:

  folks
  I looked a little more
  and it seems the psjb2 just runs masterdiscs
  with fself
  kinda lame
  very lame
  npdrm encrypted but labeled as fself
  it's a fself but I dunno what it does
  I never looked at it
  I don't really care on doing more
  if you use the masterdisc algo I provided
  and the proper key
  which I am not supplying
  you can decrypt all the psjb2 disc images
  right on pc
  grab the fself
  and use them to run them on a regular 3.55 fw
  basically security == LAME
  still interesting to see how they patched the firmware to allow masterdiscs
  they also do some auth with the dongle
  which involves crypto
  to make sure the firmware does not load without it
  but if you don't need the firmware to load the games...
  they could have added some extra keys in appldr and encrypted the damn eboots at least
  I guess they didn't have enough time or enough spu skills

Regarding FSELF from "RikuKH3":

  Real FSELFs are never encrypted. You can extract it with official unfself tool from SDK.
  But, in this FSELF I looked into (driver sf) ELF inside IS encrypted. You can say this because it's masterdisc fself, but I really doubt it.
  It doesn't look like a proper fself to me at all, in header it says that sections unecrypted, but it's not true.
  Another thing - Masterdisc Generator tool from Sony gives errors with this EBOOT (if it's a masterdisc eboot as stated, why?).

Seems the above from mathieulh may be incorrect and the eboots ARE encrypted. So much for lame security, maybe this wont be so trivial?
