Minecraft Username/Password Stealer Help

I made a minecraft account stealer using vb but using ILSpy would give the chance to anyone on finding my email and it's password and so I am asking now how can I protect my information so nobody will be able to find them? I know it's possible as for a research I was downloading many fake force op projects and when I was running them with ILSpy or HxD editor I couldn't find the form with ILSpy or the email with the password on both..
Thanks in advance.

I searched for this in google and found nothing. What do you mean?
