shellrun

cmake-build

Runs binary shell code. Also includes debugging and compatibillity features.

The goal of this project is to create a simple portable shellcode-running program.

Building

Run cmake on this repository to generate a project for your compiler. Remember you cannot mix bitness e.g. x32 shellcode on x64 shellrun To run 32-bit shellcode build shellrun as 32-bit and vice versa.

Running

shellrun [args] file

Runs the shellcode located in the file specified by the file argument. Shellrun supports clearing of registers and inserting a breakpoint before the shellcode is run, by specifying the -c and the -d argument respectivly.

Currently supported arguments:

 -c OR --clear   Clear all registers before running the shellcode.
 -d OR --debug   Set a breakpoint just before shellcode executes.
 -h OR --help    To print this help message.

Shellrun also supports running shellcode from stdin:

cat shellcode | shellrun -

Building the shellcode examples

First make sure that you have nasm installed and that it is in your global path. This is easiest with scoop. Then simply cd into ShellcodeExamples. For Windows run build.bat and for Linux run build.sh.
