What is White-Hat Sundays?

Sunday-afternoon ethical hacking for 10 to 20 year olds, genuinely state of the art and completely safe. Every attack is an on-device simulation that never leaves the room.

What will my child do?

Discover how secret codes really work, how keys are agreed in the open, how the internet carries a message, and how a defender shuts a real attack down. It starts with a white-hat pledge.

Why learn it here?

Because we teach hacking to DEFEND, never to attack, on safe simulations, with a pledge and tiered challenges so every age gets the right one. It ends with your child running safe stations for you.

What you will do

  • Take the pledge

    Promise to use these skills only to protect people, and learn what a real white-hat does.

  • Make and break codes

    Hide a message and crack one, from the Caesar wheel to an unbreakable one-time pad.

  • Share a secret in the open

    See how two people agree on a secret key with everyone watching, and no one can steal it.

  • See how the internet works

    Follow a message across the network, meet the secure handshake, and find where data can leak.

  • Break in safely, then defend

    Walk a safe attack step by step, spot the human tricks, and shut each one down like a defender.

  • Protect your family

    Run the stations for your family on the last day.

What you will be able to do

  • Make and break real codes, from the Caesar cipher to an unbreakable one-time pad
  • Explain how two people agree on a secret key with everyone watching
  • Follow a message across the internet, and find where it can leak
  • Walk a safe attack step by step, then shut it down like a defender

You walk out with a white-hat toolkit.

Your journey, step by step

12 steps, from the very first day to a real skill, ending in the Family Showcase Day.

Start here
  1. 1
    The pledge

    Sign the white-hat pledge and learn what ethical hacking really is.

  2. 2
    Everything is numbers

    How text becomes numbers, and your first code: the Caesar cipher.

  3. 3
    The unbreakable code

    The one-time pad (XOR): a code that truly cannot be cracked.

  4. 4
    Clock arithmetic

    Modular maths, the maths that makes modern codes work.

Build it up
  1. 5
    A secret in the open

    Diffie-Hellman: agree on a key with everyone watching.

  2. 6
    Fingerprints

    Hashing: how a site checks your password without knowing it.

  3. 7
    Strong passwords

    Why weak passwords fall, and how to build ones that hold.

  4. 8
    How the internet carries a message

    Follow a message across the network.

Go further
  1. 9
    The secure handshake

    How a private tunnel is built between two computers.

  2. 10
    Where it leaks

    Your digital footprint (OSINT), and the router imposter (ARP).

  3. 11
    Break in safely, then defend

    A safe attack step by step, and how a defender shuts it down.

The big day
  1. Family Showcase Day

    Run the stations for your family.

Family Showcase Day

On the last Sunday the learners run stations for their families: crack a code, spot a scam, and show a secure handshake.

How to join, in three steps

  1. Pick a time above and reserve a seat.
  2. It is free, so your seat is held right away.
  3. Come to the Lab. We email a 6-digit code to check in.

Every attack is a safe simulation that never leaves the browser. The whole month is taught to defend, never to attack, and it starts with a pledge.

A parent books the seat and gives consent at sign-up.

Small group of 10. For ages 9 to 13.

Every learner finishes with a certificate anyone can verify.

The honest bit

Learners leave understanding how real security works, pledged to use it to protect people. We do not teach breaking into real systems, and we do not promise careers; we promise real understanding you will see on Showcase Day.
