Dear All,

How can i make a patch & loader file to do the following steps :-

1. Load and EXE file ( The file is not packed).
2. Set break point after specific address.
3. Follow ESP register , and find a pattern of ASCII string like "FREE".
4. Replace the "FREE" string with "FULL".

Regards,

There is so much info about loading and patching that to answer such a question would just be redundant..

Also it is wise to use the tools available to accomplish the task you desire rather then building it out yourself.

But if you desire to build it out yourself to understand then dig in and start searching and reading more.

yeah thats possible use windbg

Thanks a lot blabberer. Appropriate your help.

on ARTeam site (www.accessroot.com) there are a lot of tutorials on loaders.. from simple to complex
