Hi webcms,

If the file can be dumped after protection, and it keeps working, then the file was protected incorrectly, or not enough, no protection features are used.

Yes.

i'm protect .net app and buy use splashscreen.
so it can't use reflector or sae after protect it.
but if i'am use DotnetDumper.
it can dump this exe.
After dump it. engima protector is gone.
and can use reflector or sae.

Well, I've added many EP_CheckupIsEnigmaOk() and EP_CheckupIsProtected() in my code, like:

Code: Select all

#if RELEASE
if (EP_CheckupIsEnigmaOk())
    InitializeComponent();
else
    Environment.Exit(0);
#else
    InitializeComponent();
#endif
And something like that in my if-else-while statements:

Code: Select all

#if RELEASE
     if (content.IndexOf("Ok", StringComparison.Ordinal) > 0 && EP_CheckupIsEnigmaOk())
#else
     if (content.IndexOf("Ok", StringComparison.Ordinal) > 0)
#endif
So app do not work after dump.
Also, I recommend to obfuscate your code before protecting it. So those steps are helpful against non-professional reverser.

P.S. Found good topic HERE
