Any CSfags in here want to help me out?

I came across this program OllyDbg, and by messing around with it for a little, obviously it's purpose is to manipulate applications processes.

I saw that you can use this to "crack" paid applications. Being a WoT fag, I really want to crack this bot and see how good it really is.

I see that the application is written in assembly, so i'm trying to figure out the pathway to the application requesting, and verifying the product key.

Upon running the program, it hits a LEAVE twice, which i'm assuming is just the application loading the main, and the login window along with it's data.

After that, if you push an exception after the 2nd LEAVE it comes to a ADD.ESP.4

Being totally unfamiliar with assembly, i'm not sure what most of this means, i can only see how it works via process. I know that somewhere in between there, i'm trying to find the line that changes a hex value that correlates to a .dll in the system files that allows the application to proceed once given the key. No matter what breakpoints i've tried, nothing has really worked.

This could be very fun, and a great learning experience if anybody would like to join in, and assist a semi-noob coder.

I doubt it was written in assembly... too much work for writing high level logic and network handling. (of course you see assembly now, after the compiler translated it to assembly.) that add esp,4 and leave stuff is about the stack frame of a function call and has nothing to do with the stuff you're interested in. assembly is the most unintuitive form of reading code, so i would recommend you to look for a decompiler to get some more high level language output. good luck, semi coder.

Everything compiles to asm
Read a books on assembly, computer architecture, and reverse engineering

Anon, I have the developer of this Bot on my skype,we're good friends.

Also, this bot was written in C# and obfuscated with SmartAssembly.

Drag the executable inside de4Dot(download this) and then open it with dnSpy (best tool for MSIL)
