shellcode-rs is a shellcode runner for Windows written it Rust and assembly. It may be useful for testing shellcode.

If you have shellcode in a file test.bin, you can run it:

shellcode-rs.exe test.bin

The runner can use multiple execution methods to test different scenarios:

• tail - Tail call uses a jmp at the end of the calling function
• ret - Ret call overwrites the return address with the address of the shellcode and then returns into it

You can try out these methods with the -m flag like so:

shellcode-rs.exe -m tail test.bin

For additional help in testing, this project also creates hello-world.exe. This binary can be run through a shellcode generator and the resulting shellcode can be tested with shellcode-rs.
