Terms of Service

Last updated 14 November 2026

1. Acceptable use

You may attack only machines launched through this platform. Attacking a

third-party host is a crime in most jurisdictions and we will assist law

enforcement if you do.

2. No flag sharing

Do not publish flags, hints or walkthroughs outside this site. Doing so removes

your ability to take the lab and gets your account suspended.

3. Fairness

• One active machine per account.
• Release the machine when you finish. Players are waiting.
• Do not brute-force flag submission; rate limits are enforced.

4. Availability

The environment is operated on volunteer hardware. We provide no uptime

guarantee. Lab content and difficulty may change between seasons.

5. No warranty

The platform is provided "as is". We are not liable for damage arising from

your use of it, including anything done to a machine you launched.

6. Termination

We may suspend any account that breaks these terms, without refund.
