Running the Linux binaries (macOS / Windows)
The challenge binaries are Linux (x86-64) ELF files. On macOS or Windows, run them inside a throwaway Linux container:
docker run --rm -it -v "$PWD":/work -w /work ubuntu:24.04 bash
# then, inside: chmod +x ./the_binary && ./the_binary
# reversing/pwn tools: apt update && apt install -y gdb binutils python3 fileThe pwn and anti-debug challenges require Linux, so run those here.
Flags look like NJACK{...}. Submit them on the Challenges page.
