Standalone command line interface for launching BOF files outside of Cobalt Strike Beacon environment. Under the hood it uses our bof-launcher library to accomplish its main task: running BOFs files on Windows (x86, x64) and Linux/UNIX (x86, x64, ARM, AARCH64) platforms directly from a filesystem.
bof-launcher is an open-source library for loading, relocating and launching BOFs on Windows and UNIX/Linux systems. It's an alternative to Trustedsec's COFFLoader and ELFLoader with some very interesting features:
* Fully compatibile with Cobalt Strike's Beacon. Can compile and run every BOF available at Cobalt Strike Community Kit and every other open-source BOF that adheres to generic BOF template.
* Distributed as a fully standalone library with zero dependency (it does not even use libc).
* Fully integrable with programs written in C/C++ and/or Zig progamming languages.
* Adds capability to write BOFs in Zig programming language - which is a low-level langauge with a goal of being a "better C". All the features of the language and rich standard library can be used in BOFs (hash maps and other data structures, cross-platform OS layer, http, networking, threading, crypto and more).
* Asynchronous BOF execution - capability to launch more time-consuming BOFs in a separate thread.
* BOF process injection - capability to launch more risky BOFs (i.e. privilege escalation exploits) by injecting it to a new process.
* Seamless support for both Windows COFF and UNIX/Linux ELF formats.
* ARM and AARCH64 support on Linux.
* Used in our cli4bofs tool that allows for running BOF files directly from a filesystem.
* Very flexible and efficient API allowing for so called BOF chaining.

Zig compiler provides working cross-compilation out of the box.
zig-gamedev project provides Win32/D3D12 API bindings that can be used on Windows and Linux.
Wine with VKD3D-Proton provides robust solution for emulating Windows runtime.
Above components combined together gives very nice development environment for building DirectX 12 applications on Windows and Linux.

Zig, DirectX 12 source code: https://github.com/michal-z/zig-gamedev/tree/main/samples/ra...
This works by capturing render output to a transient buffer and then playing it back at human-discernable speed.
