Shellter is a dynamic shellcode injection tool, and probably the first dynamic PE infector ever created.
It can be used in order to inject shellcode into native Windows applications (currently 32-bit apps only).
The shellcode can be something yours or something generated through a framework, such as Metasploit.
Shellter takes advantage of the original structure of the PE file and doesn’t apply any modification such as changing memory access permissions in sections (unless the user wants and/or he chooses Basic Mode), adding an extra section with RWE access,and whatever would look dodgy under an AV scan.
Shellter uses a unique dynamic approach which is based on the execution flow of the target application.
That's all! See you.
