Clever editing of executable files

Post by **Quantum P.** » Fri Oct 21, 2005 7:18 am

Hey, you know how you can hack ZZT and stuff by going into the executable and selectively changing certain important bytes?

Can this be done with Win32 applications?

If so, what are the recommended tools, and are there any special considerations?

You can use a hex editor (such as XVI32). I wouldn't recommend messing around with exe's then running them unless you're sure what you're changing though.

If you want to see the assember code you could try using ollydbg, but I'm not sure if ZZT is a suitable app for it (in fact I'm fairly sure it isn't).

Is there a 'sandbox' program for safely testing executables?

I actually have a strong interest in learning how to hex edit. Could somebody point me to some resources?

Awesome. I just changed a default setting in a program I have lying around. The setting was a filename string (stored verbatim in the executable), so it was pretty easy to make a slight modification.

Thanks!

I think Viovis had a webpage about HEX editing somewhere. If it wasn't Vio, it was someone esle... because I know I've read it before.

I think it's dated since I only uploaded a copy when it first came out.
