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

To modify and inject use these

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.

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 You must login or register to view this content.

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 COD4 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.

Sorry, I had to.

Has anyone tried it without the proxy cause if not then there is a chance that you don't need it. Also can someone tell me after I get the packets what and how do I can the packet. Also people have said you don't need the proxy. You can't just ignore that.

I can ignore whoever I want. And I choose to often.

And FFS, yes you need the proxy.

lagswitcher, I have no idea why yours aren't detected.
And I will join Packet Injectors, and try harder.

I can't find how to download any of these....

go google type "download wireshark" for your packet sniffing program
and google "commview" for your packet sniffing/editing/injecting program

does this packet injection actually work on cod4 multiplayer? is it worth the hassle? has any1 actually tried it? can any1 provide the edited save? or am i just sending this out to ppl who just dont have a clue. only reply if you have a real answer

Is this how people glitch the leaderboards?
