You could then find our what code accesses this pointer, move your character, and trace until you find the code responsible for sending the player movement packet. One type of methodology you could use would be to find a pointer some member, such as player coordinates, that would probably be used in a packet being sent to the server. Starting with the packets is the easiest way to find the functions necessary for creating a bot that has the ability to move, buy items, find exploits, and whatever else you would like to do. Now, let’s check which of these functions the game imports. Unless you are working with a game that uses a “heartbeat” packet with their anti-cheat, this easy methodology can be used to defeat any anti-cheat, enabling you to commence your analysis without having to worry about bypassing through other methods. The methodology used here can be applied to any game, although most games today now come packaged with very intrusive anti-cheat softwares such as nProtect GameGuard, AhnLab HackShield, or XIGNCODE3.

These anti-cheat softwares function similar to anti-virus software by scanning for known patterns of detected cheats and close the game if you are running any type of software that it deems to be cheating software. These software help increase the typing speed by means of lessons, games, and many such tools. An unsigned long in 32-bit software has a size of 4 bytes. Here we can see that the buffer has a size of 0x19 or 25 in decimal. It appears that the packet has most likely been encrypted as you cannot see “hello” in the ASCII section of the memory viewer. I typed “hello” into the chat so if we can see this in plain text where the buffer is stored, it could be possible that the packets are not encrypted and our job of logging send packets could be finished. Here we can see the game uses WSASend for sending packets and WSARecv for receiving packets. Maybe in a future blog post I’ll demonstrate how to send your own packets. 32.dll. So, I will demonstrate how to trace back from one of these functions to before the packet is encrypted on send and possibly in the future make a post on how to log received packets after they are decrypted.

I’m going to take an educated guess that there is probably more than one open connection when the game is running, maybe two since there are two functions that call WSASend. There are many different paths we can take in order to find the functions for sending and receiving packets. You will have to make sure that the drop down that says “Files of type:” has “All Files” selected or you will not find the file in Keygener Assistant as shown in the photo below. Place a breakpoint on WSASend as shown below. 0x288C. I am pointing this member out because we could possibly place a breakpoint via the memory viewer in Ollydbg at this address and trace back from a member of the network pointer. The buffer is stored at 0x180C4940. Now let’s follow the buffer in the memory view. Now we can use our analysis tools without being detected. They even have educational games so the kids can have fun while they learn.

If at all they gather themselves together to play with their kid, they don’t have the stamina to keep up with their kids. How to get started: The process of joining to play online rummy is very simple. My parents were willing to play with us as board games give all of us a time to relax together and create lots of opportunities to talk, tease each other and lots of laughter to release our pressure. Lots of projects, lots of group work, and a lot of speaking in class. As far as men of all age group are concerned, they spend nearly six hours gaming while women of all ages average to around seven hours per week. It is important to choose an unbreakable password that no hacker could guess to break into your gaming account and cause any disruption. Ollydbg will break on WSASend and you should see something similar to the photo below on the stack.
