Daily live capture the flag

A vulnerable system. A handful of clues. One day to break in.

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.

How it works

You are given access, not answers.

01

Recon

Map the target. Inspect services, files, users, and the clues left in plain sight.

02

Exploit

Combine Linux fundamentals and security reasoning to reach what was misconfigured.

03

Capture

Submit each flag as you find it. Harder objectives are worth more points.

Real tools, contained targets

Built to be investigated.

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.
