Map the target. Inspect services, files, users, and the clues left in plain sight.
Daily live capture the flag
The Range is a live security challenge played entirely from the command line. Investigate an isolated Linux target, find what should not be exposed, and capture the flags before the event closes.
Free to watch. An account is required to compete. Best played with a full keyboard.
Watch a completed event while the next isolated target comes online.

Real tools, contained targets
Every challenge runs on isolated infrastructure created for the event. Use familiar commands, inspect real services, and experiment safely inside the target boundary. No prior CTF experience is required.
