How would i make a packet sending program?
Im new to this section so please help me out and don't flame.
I want to make a program that sends packets to the program of my choice (MapleStory).
I dont want a packet editor I want to make a program that sends them,
like SMART talker sends chat packets except i want to make my own.

Sorry to question your intellect, but can you even program in any language yet?
Its a long ways to go before you will get to that.

and Ws_32.dll or whatever it is called. I tried hooking it before with gg on and it wouldent change the memory protection. If you prehooked it, gg just restores it.

Edit: Also. You can't just send it your self. You need to know the socket id too. So its sorta impossible unless you can hook it.

If you know how to find the pointer of where it stores that or maybe a point in memory where its located on the stack.

No where near impossible Wink

The reason you can't just call send yourself is if the game has some sort of custom encryption that you can't simply rip the algorithm from the client itself.

Plus, hooking send would be sort of stupid because you have absolutely no control over the interval of time between packets sent, plus the packet currently being sent would be overwritten, and again, custom encryption would make this difficult to encrypt the data in the packet you want to send in the same way that game packets are sent.

hook recv/send
get return address - 5 = call address
disassemble backwards until you find the function starting point..

using this method you should be able to find the encryptor and descrptor..unless its virtualized then you are boned..

ive never actually used the method in a gaming environment..
just to analyze malware .. :]

another thing that can giveaway the start of the function is the installation of SEH to the SEH chain at fs:[0]..and maybe int3 padding or nop padding..could be a giveaway, in anycase you should dump the asm and analyze it to get the best way to attack it Smile

kind regards BanMe
