<Slynk> Hmm had a thought : / You know how the token and token seed are made at the same time? That means the token seed isn't passed into the processor... what is? It can't be just your idps right? Unless sony doesn't use the HV to make their tokens. There must be other info passed in that determines whether you receive a dummy token or the full one. ... Just a thought. ^^;


<rms> i can make my own tokens from a nor/nand dump. just like hypervisor


----
<kevin6548> so what does that mean when a sedd is created it passes something to proccessor . nit the whole seed but a by product of creating it . is that theroy


<rms> seed is calculated from eid which allows token to be calculated. its more of a byproduct/intermediate product. if you do the math, its simple: v+s+f+h=t
</pre>


Initial import from the original text file still needs LOTS of formtting to look good in wiki...


==INTRODUCTION==
*the seed value is made from your EID (from a NAND/NOR dump, either software with payload, or hardware)
*updater manager calls spu_token_processor
*sent out of spu_token_processor
*IBM Cell Simulator (not the ancient Sony SPU Simulator from old pre 0.9x SDKs)
*seed : 80 bytes, only the first 20 are populated


The following tutorial will outline the steps necessary to build, install, and successfully exploit a PS3 "slim" or "fat" (firmware 3.15) utilizing the psgroove "service-jig" exploit (psgroove), and the payload created by grafchokolo.  This tutorial was created and tested using Fedora 9, Fedora 14, and CentOS 5.4.  If you are utilizing a different linux distribution you will probably need to make minor adjustments, keep this in mind.  Despite the amount of effort expended to try and make this tutorial "easy", utilizing the grafchokolo tools is not exactly for the "novice", but you should still try, inevitably you will learn much! ":-)"
there are two algorithms used (one's an alternative of a hashing algorithm / one's a block cipher):
* HMAC-SHA1
* AES 256 CBC - Advanced Encryption Standard Cipher-block chaining; fixed block size 128 bit, key size 256 bit - with 4x4 byte matrices


Because of the size of the grafchokolo exploit payload, the exploit itself is broken down into two different stages, a stage 1 bootstrap which is responsible for initializing the network interface, and a stage 2 payload that varies depending on what is being exploited (many of the  options are outlined in step 3).  This stage 1 bootstrap is compiled into the psgroove exploit (the psgroove exploit is well documented already, see the Appendix for links) and then programmed onto an AVR-based USB dongle device.  Once the psgroove exploit and the stage 1 bootstrap have loaded, the stage 2 payload is then sent via ethernet from a Linux/Mac workstation utilizing the sendfile tool provided.  It is this stage 2 payload that has been making the headlines on all of the PS3 news sites recently.  There is much to be written about this exploit, as it seems grafchokolo has just begun!

==USAGE==
With psgroove and the grafchokolo exploit stage 1 bootstrap compiled and programmed onto an AVR-based USB dongle device, and the stage 2 payload gelic (network) test compiled, you are now ready to exploit the PS3 with the grafchokolo exploit!
  TESTED:
    - Fedora 9 ()
    - Fedora 14 ()
    - CentOS 5.4
    - MacOS 10.5 ()
    - MacOS 10.6 ()
  PREREQUISITES:
    - linux / mac workstation
    - PS3 Slim (fat not supported at this time)
      - MAC ADDRESS
    - AVR-based USB dongle device with stage 1 bootstrap programmed
    - stage 2 payload and tools compiled
===setup tcpdump on your linux / mac workstation to receive data from the PS3===
  - filter for ps3 mac address as the ps3 uses broadcast address to send packets, keep this window visible for step 2.3 below
  - LINUX: grafchokolo_exploit$ sudo tcpdump -vv -i en0 -X -s 2048 'vlan and ether proto 0xcafe and ether src 00:9A:0A:00:5D:13'
    - listening on eth0, link-type EN10MB (Ethernet), capture size 2048 bytes
  - MACOS: grafchokolo_exploit$ sudo tcpdump -vv -i en0 -X -s 2048 'vlan and ether proto 0xcafe and ether src 00:9A:0A:00:5D:13'
    - listening on en0, link-type EN10MB (Ethernet), capture size 2048 bytes
===boot ps3 with psgroove / stage1 bootstrap===
  - remove power from the ps3 completely
  - attach the AVR-based USB dongle  device programmed earlier
  - apply power to the ps3
  - power on / disc eject
  - ps3 should not boot to XMB, stays at black screen
    - if your ps3 boots to XMB review steps 1 - 1.4 above
===send stage2 payload gelic test to ps3 from linux/mac workstation, verify network communication===

- FAILURE in tcpdump is empty


- grafchokolo_exploit$
*combo is in vsh
- If you have received successful ACKs back from sendfile / stage1 bootstrap and proper output from tcpdump (step 2.1), you are ready to
*combo &gt; 3 &lt; 10 buttons
proceed to section 3.  If however, either stage1 bootstrap or tcpdump does not look proper please review the tips below.
  - Try the test with the PS3 connected directly via ethernet to the workstation (no router or switch in-between)
  - Review sections 1 and 2 again to make sure no steps were missed
  - Look at the issues section on github for graf's code


==stage2 payload options==
<pre>Goto Network Settings
  - The following options were utilized from the grafchokolo payload, to perform the network test
Hold on L1 and R1
    - main.c
then use the left joystick, and press: down, right, right, down, right, right, down, right, right, down, right, right, start.
      - mm_init()........................:: just returns

===in order to decrypt self files, the first step is to dump lv2 memory===
  - dump_lv2 system memory, so uncomment
    - mm_init() leave uncommented (this is ?? initialization)
    - param_init() leave uncommented (this is parameter initialization)
    - gelic_init() leave uncommented (this is network initialization)
    - dump_lv2() leave uncommented (this is lv2 memory dump)
  - Make sure tcpdump is capturing the network traffic from the PS3, filter for ps3 mac address as the ps3 uses broadcast address to send
packets
    - LINUX: grafchokolo_exploit$ sudo tcpdump -vv -i en0 -w pcap/dump_lv2.pcap 'vlan and ether proto 0xcafe and ether src 00:9A:0A:00:5D:
13'
      - listening on eth0, link-type EN10MB (Ethernet), capture size 2048 bytes
    - MACOS: grafchokolo_exploit$ sudo tcpdump -vv -i en0 -w pcap/dump_lv2.pcap 'vlan and ether proto 0xcafe and ether src 00:9A:0A:00:5D:
13'
      - listening on en0, link-type EN10MB (Ethernet), capture size 2048 bytes
  - process the network traffic
    - pcap2bin dump_lv2.pcap
 
 
 
 
===setup tcpdump to receive decrypted .self===
  - Make sure tcpdump is capturing the network traffic from the PS3, filter for ps3 mac address as the ps3 uses broadcast address to send
packets
    - LINUX: grafchokolo_exploit$ sudo tcpdump -vv -i en0 -w pcap/dump_self-<filename>.self.pcap 'vlan and ether proto 0xcafe and ether sr
c 00:9A:0A:00:5D:13'
      - listening on eth0, link-type EN10MB (Ethernet), capture size 2048 bytes
    - MACOS: grafchokolo_exploit$ sudo tcpdump -vv -i en0 -w pcap/dump_self-<filename>.self.pcap 'vlan and ether proto 0xcafe and ether sr
c 00:9A:0A:00:5D:13'
      - listening on en0, link-type EN10MB (Ethernet), capture size 2048 bytes
 
 
===send .self file===
  - using the same sendfile tool used to send the stage2 payload, send an encrypted .self file to the PS3
    - sendfile <filename>.self
    - when the PS3 is done decrypting and sending the .self, you will hear 2 beeps
 
 
===process decrypted .self===
  - Each segment of the decrypted .self file just receive back from the PS3 was sent with a different ethernet protocol value, the first i
s 0xBEEF, the second is 0xBEEF+1 (0xBEF0), the third is 0xBEEF+2 (0xBEF1) and so on
  - Use the following to extract the segments from the dump_self-<filename>.self.pcap file manually
    - segment 0
      - grafchokolo_exploit$ pcap2bin -p 0xBEEF pcap/dump_self-<filename>.self.pcap <filename>-segment0.bin
    - segment 1
      - grafchokolo_exploit$ pcap2bin -p 0xBEF0 pcap/dump_self-<filename>.self.pcap <filename>-segment1.bin
    - segment 2
      - grafchokolo_exploit$ pcap2bin -p 0xBEF1 pcap/dump_self-<filename>.self.pcap <filename>-segment2.bin
  - Use the following to extract the segments from the dump_self-<filename>.self.pcap file automatically with the handy dump_segs_from_pca
p.sh script
    - dump_segs_from_pcap.sh dump_self-<filename>.self.pcap
  - The segment load addresses are extracted with the following:
    - investigate decrypt_self.c for this information
 
 
 
==ANALYSIS==
 
===Almost at the finish line!  You are now ready to load the decrypted .self segments into IDA Pro===
  - Load each segment into IDA Pro using the proper load address for each segment
    -
  -
 
 
==PROFIT!==
  Now that you have successfully exploited the PS3 "slim" utilizing the grafchokolo expoit, only your imagination limits the potential discoveries that await!  The inner-workings of the PS3 system console have always been shrouded in mystery, but that is no more. ":-)"
