Just downloaded winpcap and made a little wow sniffer.
Files included;
WinPcap_4_0.exe
Setup.exe
Packet.exe
Packet.au3
Install WinPcap 4.0
Then install Packet X 3.2 (Setup.exe)
Run the script via the au3 or the compiled *.exe file.
For "no trusters" Both WinPcap 4.0 and Packet X 3.2 can be downloaded from their official homepages.. google them if needed.
Start World Of Warcraft, log in on your char.
Press "Start Capture".. and the program will begin to tap the packets that contains movement data.
You can stop/pause the sniffer at any time and resume it.. you can also clear all the data.
Aditional features is the "on top" checkbox that ensure that the Packet Sniffer window will always stay on top.
You can also set it to Transparent so it doesnt steal that much of the screen.
The code can easily be modified. But it was made a bit fast, so it is not that well structured.
Download it
