A shellcode runner write in Rust use windows-rs.

Install rustup, use nightly toochain.

rustup default nightly

Use msfvenom generate shellcode for test.

msfvenom -p windows/x64/exec CMD=calc.exe --platform win -f raw -o calc64.raw

Build:

cargo build

Usage:

rs_shellcode USAGE: rs_shellcode.exe [FLAGS] [OPTIONS] -f <file> FLAGS: -b set breakpoint in debugger -h, --help Prints help information -V, --version Prints version information OPTIONS: -f <file> shellcode path -o <offset> shellcode offset 

Run:

./target/debug/rs_shellcode.exe -f <SHELLCODE_PATH>

When your shellcode not start at offset 0, you can specify the offset use -o:

./target/debug/rs_shellcode.exe -f <SHELLCODE_PATH> -o 0x30

Run with breakpoint flag (-b):

./target/debug/rs_shellcode.exe -f <SHELLCODE_PATH> -b

use this flag, you can break just before your shellcode in the debugger, which will make your life easier.
