Forum Thread: Setting Up Zeus Botnet

OK so I have the source code to setup up the Zeus Botnet, but when setting up the C & C server I think its missing php-mbstring which I have no idea how to code a php-mbstring, from what I have read and please correct me if I am wrong the php-mbstring, but I think it is for when you have multiple php querys and the php-mbstring connects all of them together, but I'm not really sure please help thank you...
