THEM?!CTF 2026

THEM?!CTF 2026 is an online, worldwide jeopardy-style Capture The Flag competition organized by THEM?!

The event is designed to be beginner-friendly while still offering enough depth for intermediate and experienced players. Challenges will span a wide range of difficulty levels, so newer players can learn and participate/slop, while stronger teams can expect harder problems that require deeper technical skill actual brain functioning.

We plan to feature 40+ challenges across the following categories:

Crypto, Web, Reverse, Pwn, Web3, OSINT, Forensics, and Misc

For THEM?!CTF we put a lot of effort into original yet interesting challenge design. We are paying special attention to reducing low-effort solving aka. slopping and flag-sharing through very intentional challenge design choices, with the goal of making the event fun and more competitive for everyone.

Sharing flags, solutions, or even the slightest hint is STRICTLY forbidden, and will NOT be tolerated.

The use AI is not forbidden, since it cannot be reliably proven, but relying on it too much tends to be embarrassingly obvious.

The event is fully online and open to players worldwide.
There is no team size limit.

We wish all players and teams best of luck.
