    JaicraB on Cobra USB JIG Protection RTOC Trick for PS3

    Today Spanish PlayStation 3 developer JaicraB has explained the Cobra USB JIG protection RTOC trick implemented for the PS3 against cloning the device.

    To quote, roughly translated: Flynn sent me this text explaining this protective carrying the Cobra, I hope it will open the eyes of those interested in reversing the dumps.

    EXPLAIN RTOC COBRA TRICK

    The JIG Cobra has several protective measures to ensure that your code could not be used correctly even if your code could be dumped.

    This trick RTOC in the registry is the first used for this purpose in addition to hinder analysis.
    Registration is initially RTOC stored in the battery to keep the RTOC of lv2 and power it back later:

    [Register or Login to view code]

    At this point we have to explain that the OFFSET DELTA. DELTA OFFSET is a method used in the x86 in its original moments in the creation of computer viruses, to calculate the memory address in which we are in the sea of ​​bytes in RAM.

    In the original time a computer virus when I did not know where he was pulled into an executable,
    depending on the executable it could be an initial site or another, for it was invented DELTA OFFSET.

    DELTA OFFSET can be used in any system, the procedure is:
    • Using the record that indicates the current execution address (or the next depending on the system)
    • Reducing the size of the previous code we use the value obtained from the registry.

    Knowing this, and taking for example the x86 processor where the EIP register can not be read directly invented the trick make a call to a "subfunction" which is simply the following line to the call:

    [Register or Login to view code]

    X86 call instruction saves the top of the stack the address of the next instruction to itself. Thus using pop draw from the top of the stack this value, and stored in eax for example, and having the memory address where we only subtract the above would be missing and we have the exact calculation.

    The PowerPC can use this trick using the BL instruction is equivalent (LINK BRANCH), which jumps to a "subfunction" but before you save LR in the record the following address to BL.

    [Register or Login to view code]

    At this point we see the trick used for the creation of the RTOC of charges at this time. If you look both r0 and RTOC are passed to 0:

    [Register or Login to view code]

    Subsequently, given the value 0x11DE0 to RTOC:

    [Register or Login to view code]

    A r0 is given the value 0x920:

    [Register or Login to view code]

    R0 is subtracted from the value of RTOC:

    [Register or Login to view code]

    Unlike the PowerPC x86 LR register can be read directly with mflr instruction, we put in RTOC the value obtained by the delta offset:

    [Register or Login to view code]

    To calculate the delta offset subtract final instructions executed before the delta offset, which were 4, or 16 bytes:

    [Register or Login to view code]

    Finally we add the value of r0 at the end of the delta offset RTOC, storing the result in the RTOC and this already takes RTOC suitable for this hook:

    [Register or Login to view code]

    It takes having the RTOC stored in the stack 3 arguments that the hook received:

    [Register or Login to view code]

    You call the function of the charges where the first argument will check for command 0x8202 (a special command to the usual):

    [Register or Login to view code]

    After making the necessary steps as charged, the battery recovers the original RTOC, like the arguments the hook received, it executes the original instruction that was overwritten in the syscall entry 379 (in this case) to have our hook, and call the original syscall lv2:

    [Register or Login to view code]

    Upon returning to retrieve the original LR from the stack and returns to the prompt

    First before anything we want to clarify that this thread is dedicated to community members and therefore DHorg the comments made about what this information is or is no longer cause is nothing more than mere envy, oppression, or that are to dispute. For outside the dates of publication and that are linked to circumstances that can slow or speed up the publication.

    Cobra Payload as JFW DH Plugin
    • At the moment due to problems outside the scene Jaicrab the development of this plugin been in a paused state

    New Linux Item
    • The JFW DH was gonna be no less, that includes 2 options to use Linux back in the console, in this regard are:
    • Install
    • Boot

    Preloader, Recovery Boot - The JFW DH includes a preloader that is responsible for:
    • Back of the 3 RAW Flash to external media (USB)
    • Flashing copies from an external drive (usb).
    • Update the Preloader
    • Home of the flash write access (not necessarily more alejandro or substitutes)
    • The advantages are not required reinstalling all the PUP (from hardware checks) do not need to do: composite or go through the recovery

    Services Packs
    • These packs include the basics in order to use plugins, loaders, ftp, etc.

    Compatibility with Games and Applications
    • JFW DH uses a 341v2 core, this does not mean not being able to play all over now without patching.
    • The JFW DH is compatible with games that include between 3.56 down, including the current patched to 3.55
    • JFW DH runs natively games until 3.56 (original disks) without having to upgrade.
    • PSN games that require npdrm 356, are also supported without upgrading (the current cfw not give this support)
    • No need for a valid signature on the executable
    • Not going to make a port to 3.55 of this JFW DH, since it includes much more than himself 3.55

    Members of the Project
    • Alejandro (special collaboration) = Central Core, security, preloader
    • Jaicrab = Core, central TheGrid, linux
    • DemonHades = xmb Categories, Organization, Implementations

    • Flash dump the 3 partitions on an external (USB)
    • Restore partitions Flash via a dump on external media (USB)
    • Mounting partitions Flash write
    • The preloader can be updated.

    TheGrid: TheGrid is a new category that includes a plugin manager, service packs, but also the name of the loader plugins. The plugins can launch tasks in the background.

    Various details:
    • JFW The DH is based on the Firmware 3.41 v2 but is fully compatible with games requiring firmware 3.56 and earlier (3.55 patched games included).
    • Game discs that require firmware 3.56 or earlier without having to spend to update the console.
    • The PSN games that require a compatible NPDRM 3.56 without updating.
    • Executables do not need to be signed.

    And the video of JFW DH: The video shows the personal side with a CFW Coldboot / Soundboot changed and a new category "RetroLaunch" Minis are supported and saves them (PS1/PS2 games and their backups will also be part of this category).

    Those who wondered what the icon is black "JaiCraB", it must match the Firm USB Loader. DemonHades invites us to participate in their topic in order to advance the project as still no publication date.

    I dont think so, I think they are referring to those that have a backward compatible console that can play ps2 games will be able to boot backups, since the current firmwares are messy solutions.

    Adrianc1982 Afaik all can run with the software emulation found/fixed earlier, (CFW that is) but theese that only use softwares sucks i think that i mean really sucks, but atleast there is. (might be wrong, but i remember about it some weeks ago)

    This is going to be one truly awesome CFW anyone knows why they choosed 3.41 over 3.55 ? if there is any advantages i missed?
