           This module allows you to generate a Windows EXE without having a shellcode in the file. and rather have it generated at runtime. This is useful for reducing the detection ratio of your payload.
           it will also use few technique to avoid runtime detection such as,
           time obfuscation server_time->sleep->server time again.
