White-Hat Sundays
Sunday-afternoon ethical hacking that is genuinely state of the art and completely safe. Discover how secret codes really work, how two people can agree on a key with everyone watching, how the internet carries your messages and where they can leak, and how defenders shut a real attack down.
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.
How every day feels
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.
- 1The pledge
Sign the white-hat pledge and learn what ethical hacking really is.
- 2Everything is numbers
How text becomes numbers, and your first code: the Caesar cipher.
- 3The unbreakable code
The one-time pad (XOR): a code that truly cannot be cracked.
- 4Clock arithmetic
Modular maths, the maths that makes modern codes work.
- 5A secret in the open
Diffie-Hellman: agree on a key with everyone watching.
- 6Fingerprints
Hashing: how a site checks your password without knowing it.
- 7Strong passwords
Why weak passwords fall, and how to build ones that hold.
- 8How the internet carries a message
Follow a message across the network.
- 9The secure handshake
How a private tunnel is built between two computers.
- 10Where it leaks
Your digital footprint (OSINT), and the router imposter (ARP).
- 11Break in safely, then defend
A safe attack step by step, and how a defender shuts it down.
- Family Showcase Day
Run the stations for your family.
Why this is different
Pick a time and book
12 sessions, the last is the Family Showcase Day.
12 sessions, 26 Jul to 11 Oct
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
- Pick a time above and reserve a seat.
- It is free, so your seat is held right away.
- 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.
