Packet injection as a way of ‘hacking’.
Changing values in packets and injecting them back into the network so the changed values are read and applied instead of default values.
Problems:
* Identifying which values to change in what packets
* Need a combination of an ELF file and probably other stuff
* Many others as soon as we get started
Packet injection as a way of enabling CVARs
Copy write edited game save and inject a packet back to the server to respond to the overwriting query to trick the server into thinking the game save has been overwritten back to its default info.
Problems
* The form Set “CVAR” doesn’t work anymore so need to include CVAR commands in custom code.
* Which packets to inject and how to modify them to be accepted as genuine by the server, time stamps etc.
* Copy writing the game save in a format which can be read by the PS3
How To 'Packet Sniff'
Use this to packet sniff:
Wireshark - Freeware
Wireshark is a good analyzer too.
To modify and inject use these
Packetyzer - Freeware
Commview - Shareware
These also have packet sniffing functions but can also modify and inject packets.
Make sure to set these to monitor traffic in promiscuous mode. Close all other programs that use internet such as browsers or IMs as to filter out irrelevant info.
Set Up Your Network
To get good network traffic use one of these methods:
* Play the PS3 through your PC via PS3 proxy – mixed results. (method shown below)
* Connect your PS3 and PC to a hub then connect the hub to a router
* Set your network up so all traffic runs through a gateway with the IP same as the routers IP and set the sniffer to that IP.
see how it goes with your current setup first. You may get decent results already.
Starting packet sniffing:
This method uses the PS3 proxy. If you have your network set up so you can see all network traffic without PS3 proxy then just use the packet sniffers as is.
1 Download PS3 Proxy Here
2 Go to Start > Run then type "cmd" and click OK. In the command box that will pop up type “ipconfig” and press enter. Copy down the number that is your IP address, usually something like 192.168.0.2.
3 install PS3 proxy. Go to C:\Program Files\CF3B5\PS3.ProxyServer and click on PS3.ProxyServer.GUI.
4 In the PS3 proxy window type in your IP address and check the ‘PS3 mode’ box and click start.
5 Install Wireshark or Packetyzer or Commview or whatever you like. In the program select the network adapter of your PC if it is not already selected.
6 On your PS3 go to Settings > Network Settings > Internet Connection Settings > Custom. Keep on pressing X or right until you get to ‘Proxy Server’ and choose ‘Use’. Enter the same IP you put in PS3 proxy. Keep on pressing X or right until it reaches the end and choose not to test connection.
7 Start your packet sniffing program to capture packets, go to your PS3 and play COD online multiplayer.
8 Once you played a couple of games or whatever, go to the packet sniffer and stop it. Look through the packets and see if you what has been captured.

To me this looks like it was a while back when Hunter was experimenting with a few methods. EXT is the File System of Linux. Notice how he was using FW 3.00 also note the word injected, This is your first hint :p
copied and pasted this from another thread.

Wutz n MW2?
Honestly. This is a lost cause. To my knowledge, there is no packeteering program that would locate/edit/send the packets you need without messing the game up (would in turn feel like you're lagging). One match would contain countless packets, everything from movement, to hit markers, to button presses (which translates to playing your avatar's animation on another player's screen) are sent. Granted, what Unkn0wn is probably referring to is Hunter injecting data TO his PS3, not the game server.

it can be done on ps3. i have seen guys doing it on socom.[ame=https://www.youtube.com/watch?v=Q6UCkqq4t9s]YouTube - SOCOM: Confrontation - Hacked Pt. 2[/ame]
hes using your package injection theory
