Hello,
These days alot of servers use a custom wow.exe to secure their servers and inject custom code.
Because of the modding , the md5 of the .exe changes so that hacking-tools (wow-emuhacker , hitchhiker , ...) cannot connect anymore.
I know how to extract the md5 but i haven't found out yet how to add it to an existing tool.
If someone knows a way to do this , please let me know.
edit: retyped the whole post to make it more understandable
