OllyDbg question.

[KieuVanQuan]

Is it possible to edit certain values of an exe file in OllyDbg? (The exe is unpacked already so no protection) For example change a value from 5 to 6 or change a file path or dll call...? Or can I only jump certain processes?

Do you just want a hex editor or...?

 

For example if I want to change a string from "C:/Something.exe" to "C:/SomethingElse.exe" inside an executable I'd just open it in a hex editor and find and replace.

I want to change integers too.

I tried hex editing but I cannot find that specific hex address in hex editor.

What hex editor are you using? It should be as easy as selecting the type of thing you're searching for and the value of that then searching for it.

My hacking days are well behind me so i haven't used ollydbg in years so I cant tell you how to do it specifically but you should be able to replace a function with commands to overwrite the data you want changed but you should be able to edit the data directly if memory serves me right.

He is using the best hex editor out there. OllyDBG.

OllyDbg is a little overkill for just changing some static values. I can't precisely remember how to do it in OllyDbg because I mostly use x64dbg and IDA due to lack of 64bit support in OllyDbg. But if my memory serves me right you just go into the memory dump window and right click the address you want to write a value to and select modify. 

 

But if you are just changing static values in something a simple hex editor is far easier.
