AntiDebugging in Delphi

[GautamGreat]

Hey. I need some help. I wanna program a application which is fully protected from RCE. Means if it will detect any PE tool or debugger it will self destroy.

Check that post, it contain a paper with the most common techniques to do that.

The simplest way to check if an application is running inside your code is call FindWindowA and looking for the name of the dialog.

That's useless since cracker can just set a BP in the api you using for it or just freeze the process,

would be useful only if you have a online licence system able to ban the licence.

Finally I decided I will make a online registration system and use FindWindowA api to trace any debugging or pe tools if process detect the license will ban automatically.

Make it able to detect breakpoints and md5 checksums internally too

I love coding in delphi/pascal... here is a great site for source code/snippets and inspiration:

I don't like Pascal/Delphi.
But I think Lazarus (Delphi) is cool! http://www.lazarus-ide.org/
Lazarus - The professional Free Pascal RAD IDE!

is the most updated Delphi with the best IDE.
