Welcome to Le Tour Du Hack CTF 2026

Whether you are here in person at Edinburgh Napier Merchiston Campus or joining us online, we are glad to have you.

Event Schedule

Date: 17 May 2026
Venue: Edinburgh Napier Merchiston Campus
Format: Hybrid

Prizes are available for in-person participants only.

You can compete solo or as part of a team. The maximum team size is 4 people.

Pick a team name you are happy seeing on a the scoreboard.

Flags will follow this format:

LTDH26{.*}

For example, a valid-looking flag might look like:

LTDH26{this_is_not_a_real_flag}

Submit flags through CTFd to score points. If it does not submit, it is not the flag. This is both advice and emotional support.

Challenges have fixed point values.

Hints are available, but they may cost points. Use them wisely, or ignore them until the final 10 minutes like most folk.

First bloods get stickers.
The first user to solve our harder challenges get the glory, a sticker.

We want everyone to have fun, learn things, and avoid making the infrastructure cry. Please follow these rules:

Do not attack the CTF infrastructure.
Only attack the challenge targets and files that are clearly provided for the CTF.
Do not brute force.
Challenges are designed to be solved through skill, logic, research, and creativity, not by melting the server.
Do not share flags.
Your team should solve the challenges yourselves.
Do not share solves during the competition.
Writeups, hints, walkthroughs, and “accidental” spoilers should wait until after the event.
Be kind to other participants, organisers, volunteers, and the venue.

Breaking the rules may result in points being removed, disqualification, or being asked to leave the event.

If you get stuck, confused, lost, or your laptop starts behaving like it has joined another team, help is available.

We may not give you the answer, but we can help point you in the right direction.

Here are some useful places to look when the challenge is being anoying and the answer is hiding in plain sight:

Keep an eye on the announcements during the day. If anything changes, we will let you know through the CTFd notifications.

Good luck, have fun, and may your flags be valid first time.
