Format

The Preliminary Round is a standard Jeopardy-style CTF.
The CTF platform is open from 05.10 to 09.10, each day from 10:00 to 22:00 UTC+3.
Each participant gets a single 3-hour attempt. When you click "Start solving" and confirm, your 3-hour timer begins. Once the time expires, your user account is locked and your attempt is recorded.
To get the full 3 hours of play time, make sure to start your attempt before 19:00!
If you experience any issues during your play time, please contact Oliver Kikas on Discord: @localhost1001

Scoring

Each challenge has a fixed point value reflecting its difficulty (shown on the platform).
If hints are available, unlocking them applies a point deduction (displayed before you confirm).
Ties are resolved by (1) shortest elapsed time to reach the score, then (2) fewest incorrect flag submissions.

1. Collaboration, sharing flags/solutions, or discussing challenges with anyone is prohibited until Preliminary Round has ended.
2. Only interact with services, hosts, and URLs explicitly listed in the challenge descriptions. Do not target other infrastructure.
3. Denial-of-service, traffic flooding, destructive actions, credential stuffing/brute force against CTF platform logins, vulnerability scanning of non-scoped assets, and automation that noticeably degrades challenge services are forbidden.
4. The standard flag format is "KTMTY{...}" or "KTMTY-...", unless stated otherwise in the challenge description.
Do not share flags publicly or privately while the event is ongoing.
5. Use only the credentials issued to you. Do not share your login credentials or allow anyone else to use your account.
6. If you find a challenge bug, outage, or unintended exposure of user data, report it immediately to support via Discord.
