    PS3 Firmware 3.56 Update is Now Available, Details Incoming

    Update: It appears Mathieulh is incorrect as GFI Security's Chris Boyd has confirmed Sony wrote the ability for remote updates into its terms and conditions since at least 2006 stating the 3.56 rootkit is not new.

    Just under two months since the previous PlayStation 3 system software update has passed, and today Sony has released PS3 Firmware version 3.56.

    For those wondering, PS3 JailBreak and Custom Firmware users can still access PSN via the bypass methods but read the IRC log below as a "rootkit" was found in PS3 Firmware 3.56 which reportedly allows Sony to scan for PlayStation 3 Custom Firmware or any unofficial homebrew software.

    Download: PS3 Firmware 3.56 Update (US) / PS3 Firmware 3.56 Update (EU) / PS3 Firmware 3.56 Keys / PS3 Keylist (.xls) / PS3 Tools

    According to VP of Network Operations Americas Eric Lempel via Sony's official blog on the update, to quote: "A new PS3 system software update, v3.56, will be released soon. This is a minor update that adds a security patch."

    Needless to say, if you value PS3 homebrew, jailbreaking, downgrading or accessing PSN on a hacked PS3 it would probably be wise to hold off updating until PlayStation 3 developers can examine the 3.56 update.

    As always, more details to come as they are available and below are some preliminary 3.56 Firmware examination details from PlayStation 3 developers via IRC:

    KaKaRoTo: nice... it's full of spkg files now .. probably a new crypted pkg format
    KaKaRoTo: possibly with a new signature that only ps3swu.self can read, but without the ecdsa fail
    KaKaRoTo: humm.. seems I was misled, there's no spkg files in 3.56
    KaKaRoTo: ok, so they added a new .self file in the PUP
    KaKaRoTo: and it seems it contains a key that we don't know about
    KaKaRoTo: yeah, probably a newer ps3swu.self that is more secure
    KaKaRoTo: but they kept the old one for people upgrading from older firmwares
    KaKaRoTo: the new ps3swu.self probably decrypts and uses the new self
    KaKaRoTo: ok, so we need new keys for everything now :p
    KaKaRoTo: I just pushed to ps3tools and ps3utils, fixes to allow pup/puppack/pupunpack to identify the new files in the pup

    rms: try it.
    KaKaRoTo: rms, what's that blob you pasted ?
    adrianc: the new key
    KaKaRoTo: ha, cool
    KaKaRoTo: rms, if you know how and can extract all the new keys, please do and send them to me so I can upload to my ps3keys repo
    adrianc: the new keys are all in there
    rms: KaKaRoTo: i believe it's a lv2ldr key
    rms: erk/riv/pub its all in one block
    rms: i forgot the order its in though, it should be in that, its been a while
    KaKaRoTo: I don't even know how you did to find those keys :p
    adrianc: its in the data section of the elf usually
    rms: its really simple
    adrianc: after that look for references for blocks of data
    rms: really KaKaRoTo, i think even you could do it
    rms: adrianc: or something out of place
    adrianc: helps to compare to older versions where you already know the key position
    rms: and has a set of 8 00s
    adrianc: KaKaRoTo 3.56 key works?
    KaKaRoTo: adrianc, didn't try, not planning on trying atm
    KaKaRoTo: not until I have ~/.ps3/ files prepared for me by someone :)
    KaKaRoTo: lv2 3.56 decrypted :)
    rms: keyset?
    KaKaRoTo: pushing to
    KaKaRoTo: pushed
    rms: ok
    rms lv1 is also new
    rms lv0 also
    rms and also the spu stuff apparently
    KaKaRoTo: humm.. I wonder who has the lv0 key
    adrianc: i dont think lv0 is available
    KaKaRoTo: iso keys are now pushed
    KaKaRoTo: also, now, if we want to repackage things (unless they screwed up the ecdsa *again*), we'd have to change the keys in all the loaders... which means repackaging all the *ldr and iso selfs...
    KaKaRoTo: so even more risk of bricking :p
    KaKaRoTo: pushed spp keys
    KaKaRoTo: the missing keys are for 'app', 'ldr' and 'rvk'
    KaKaRoTo: btw.. where is that 'ldr' coming from ?
    KaKaRoTo: and I can't figure out who decrypts lv0
    KaKaRoTo: it can't be metldr since that one can't be changed
    KaKaRoTo: and there's no lv0ldr
    eussNL: bootldr decrypts lv0 afaik
    KaKaRoTo: there's no bootldr either
    adrianc: bootldr and lv0ldr arent in the pup
    Matt_P: not part of coreos
    Matt_P: and theres no such thing is lv0ldr
    Mathieulh: Sorrowuk I suppose modchip manufacturers will start shipping nor/nand programmer soon..
    IceKiller: Mathieulh why? just get a at90 based thing
    IceKiller: i already told you about that Mathieulh :p
    Mathieulh: SLC the bootchain is pwned, no matter what
    Mathieulh: you can always downgrade the coreos
    Mathieulh: 3.56 has nice new stuffs in there :P
    Mathieulh: like remote code execution upon login
    Mathieulh: I assume they probably added some syscalls for lv2 integrity checks
    Sorrowuk: Who wants to resign lv2diag.self for 3.56 so it works again ? I would do it but I dont know how to rebuild the signature after I change the authid . Some people are stuck in service mode in 3.56 :P lol
    Mathieulh: Sorrowuk you can't
    Mathieulh: 3.56 pretty much has a built in psn rootkit
    Sorrowuk: psn rootkit ?
    noone: but if we could rip-off the fw that shit would be erased
    noone: that was the only thing stopped sony to _auto_ update your fw
    Mathieulh: noone it's not that simple
    Mathieulh: the server awaits a proper reply
    Mathieulh: and that reply isn't in the firmware
    Sorrowuk: so people are stuck in service mode?
    Mathieulh: they force updaters and lv2diags to be signed with the new 3.56+ app key
    Mathieulh: and of course we don't have the private key for that
    Mathieulh: if they want to get out of service mode they have to downgrade first by reflashing the nor externally
    Sorrowuk: Sony should release a new lv2diag.self for everyone to get out of service mode. thats not very nice of them XD
    Mathieulh: btw interestingly enough
    Mathieulh: it seems the new signature check for the updater (and supposedly lv2diag) is skipped on DEX consoles
    Mathieulh: I assume that's to allow debugs to downgrade
    Sorrowuk: so if you used a nand flasher and flashed the nand of a retail with a debug nand, you would have a debug console
    IceKiller: Sorrowuk no
    IceKiller: won't work.
    About 3.56 if the updater/lv2diag application keyset revision is lower than 0x0D, lv2 will refuse to run it.
    Mathieulh: the fail is the following anyway, decrypt your hdd cache partition /dev_hdd1 using the hdd decryption trick right after the 3.56+ updater starts (but before it updates) (just use the back switch), then replace the coreos package, with one you resigned which has 3.55 coreos but 3.56+ in info0 (or the value 0xA0 at offset 0x2C) then reencrypt the hdd partition and put the hdd back, because the
    Mathieulh: update status flag will be set, the updater will start and flash the resigned 3.55 coreos package (the fail works because they haven't changed the packages signatures, not like they can)
    Mathieulh: then you can use service mode again and flash whatever crap
    Mathieulh: doesn't work on slims cause the hdd decryption trick is fixed there
    Mathieulh: they btw can't fix it in the fat ones because it's hardware related
    Mathieulh: (encdec device)
    Mathieulh: also it's not the decryption that's the issue
    Mathieulh: appldr decrypts those selfs fine
    Mathieulh: the problem is lv2 wont run them
    Mathieulh: lv2 checks the app revision
    Mathieulh: if it's lower than 0x0D it wont run it
    Mathieulh: and of course you can't change an old one to 0x0D or higher
    Mathieulh: cause then appldr will check the signature with the new pub key
    Mathieulh: and you lack the private key
    Mathieulh: of course if anyone manages to pack a new PUP properly, then you don't need to do the hdd crypto shit to
    Mathieulh: but I haven't looked at the new pup format
    Mathieulh: rofl I am looking at the new appldr
    Mathieulh: and they hardcoded/revoked tons of new auth_ids in there
    Mathieulh: how much do you want to guess that those are the ones of the previously signed homebrews ? xD
    Mathieulh: oh ! wait
    Mathieulh: those aren't auth_id
    Mathieulh: those are hashes
    Mathieulh: 20 bytes each
    Mathieulh: sha1 considering the lenght
    Mathieulh: selfs
    Mathieulh: that has defintely something to do with why npdrm homebrews stopped working
    Mathieulh: in fact I am running the new appldr in anergistic
    Mathieulh: and it wont decrypt these demos
    Mathieulh: I mean homebrews
    Mathieulh: well you get the idea
    naehrwert: so new demos need new firmware version then, but what if they want to release a new demo and don't want to update fw?
    Mathieulh: naehrwert they just have to encrypt/sign it with new keys
    n00b517: PS3 3.56 _Private_ key: 7d583155485c3c7e3e6f626a4a4d4351322c444136 [!!!]
    an0nym0us: well it works
    an0nym0us: not sure how it was obtained
    DPxD3v: nice
    misteriou: 7d 58 31 55 48 5c 3c 7e 3e 6f 62 6a 4a 4d 43 51 32 2c 44 41 36
    Djinn: this is being posted all over the place
    rms: $ printf "Private Key: 0x00"; cat /dev/random | head -c 20 | xxd -ps
    rms: Private Key: 0x00fe7027da6ce683aa111b3ebbe06b43ddf15bf7c3
    rms: remember that
    MonkeyBoy: we got all the 3.56 Public keys

    Finally, Becus25 has released several PS3 tools recently as follows: GeoHot's PS3 3.55 Category_Game.xml File, PS3 Public Tools GUI Rev. B, PS3 Nas_Plugin Extractor 3.55, PS3 3.56 Lv12 Decrypt, and PS3 Nas_Plugin Extractor 3.56. Details on each are below:

    GeoHot's PS3 3.55 Category_Game.xml File:

    This is GeoHot's category_game.xml file which is written in dev_flash/vsh/resource/explore folder when you install PSJailbreak. This file is added to the existing one and not replaced at all. Also he writes a new nas_plugin.sprx to dev_flash/vsh/module.


    PS3 Public Tools GUI Rev. B:

    There are two modes (developers who have installed the SDK) and non-developers)
    For the first one (developers) these are the instructions:

    1) Open PS3 Public Tools GUI.
    2) Browse the MAKEFILE of your project.
    3) After find the makefile (without closing PS3 Public Tools GUI), open your Windows cmd and go to the folder where there are the files you want to sign.
    4) With the root set on cmd, type: make & make pkg
    5) Open the window of PS3 Public Tools GUI and moving the mouse on the window you will see how the make button will be activated. Push it, and your self and pkg files will be signed!

    For the second one (non-developers) these are the instructions (use this mode if you already have the elf, self and pkg files unsigned but compiled):

    1) Open PS3 Public Tools GUI.
    2) Uncheck developers option.
    3) Browse your ELF file.
    4) Push on the MAKE button.

    NOTE: The application only will sign the self and pkgs files if they already exists. If not, the process won't be done.

    PS3 Nas_Plugin Extractor 3.55:

    This tool allows you to extract nas_plugin.sprx from a 3.55 (now, only 3.55...) pup sony update. After extract this module, you can decrypt the module using fail0verflow's unself tool.

    To extract the module just run my app and browse the 3.55 pup file. You will find the file in C:\depkg after the extraction.

    PS3 3.56 Lv12 Decrypt:

    This tool allows you to decrypt CORE_OS_PACKAGE.pkg, lv1.self and lv2_kernel.self of 3.56 official firmware.


    1) Download 3.56 official firmware pup file.
    2) Run the app and browse the file.
    3) Push the button. The files will be decrypted and saved in C:\BPS3Dec

    PS3 Nas_Plugin Extractor 3.56:

    This tool allows you to extract nas_plugin.sprx from a 3.56 (now, only 3.56...) pup sony update. After extract this module, you can decrypt the module using fail0verflow's unself tool.

    To extract the module just run my app and browse the 3.56 pup file. You will find the file in C:\depkg after the extraction.

    Then, if you want to decrypt the file extracted, open fail0verflow.rar included with this package and extract the folder called fail0verflow to C:\.

    After that, copy your nas_plugin.sprx inside this folder and run the bat file that will be in C:\fail0verflow. Now you will already have your nas_plugin decrypted also!! (ALL THANKS TO FAIL0VERFLOW FOR THIS GREAT TOOL!)

    Exclamation PS3 Firmware 3.56 is here!

    WHAT DO?!

    I wonder who will be the first to patch this...

    I just got the update message too.

    Knowing somebody has a PS+ sub and 4got to turn off automatic updating, they will tell us if the installed apps (ftp, multiman) still works. If so it may be as simple as patching the update. But that also can be not so simple. Best of luck.

    And I was just enjoying playing online again... At least the DNS patch still works for now.

    "A security patch" LOL, do they really think they can stop CFW? $ony really have no clue do they? Why don't they stop trying to patch holes they can never fix and just fix the bugs and add the features everyone is asking for... I'm really surprised the firmware updates get bigger with less features.

    Shouldn't they be getting smaller? I think we need a PSNLOVER for PS3 then they will never stop us getting online.

    According to a friend, You cannot run blackbox / FTP in 3.56

    But you CAN run stuff like trophy editors and NES emulator.

    Now will Sony really ban people who are on a legit 3.56 Firmware but running a nes emulator? I think no haha. But i yet to have updated, i'll do it soon though to test out the apps.

    Question: Where is the CFW stored? What if i repalce my internal HD with the CFW and all the tools, against my Original one.

    Other words, I have recently installed a 500 GB, with CFW. When i now switch back to my Original 120 GB HD, will i be on 3.55 Official FW again?

    downgrade possible?

    Has anyone that updated checked to see if the console could be downgraded back to 3.55? or lower?
