Learning kitGrades 6-8

Computer science: cybersecurity

Think like a hacker, defend like a pro

Crack codes and hack a password in CryptoLab, see why two-step login stops a stolen password, sit in the middle of a fake cafe Wi-Fi and read what it catches, and spot the tricks social engineers use. Ages 11 to 14 or grades 6 to 8.

Time
About 2 hours, in two sittings

5 steps, 2 of them in CryptoLab
You need
A computer or Chromebook with a keyboard. Printing is optional: every step works on screen. No account needed.

$5 for one learner: every step, the CryptoLab activities that check the work, the printable lesson, and the certificate with a page of the learner's own work.

Code and password challenges ticked off one by one: Crack the Caesar Code, Find the Shift, Secret Instruction, Hash Detective and Password Cracker.

The 5 steps

  1. 1Crack a codeIn CryptoLabCodes hide messages from anyone without the key. Crack three in CryptoLab, then make one of your own and see why a shift cipher would not protect anything today.
  2. 2Hack a passwordIn CryptoLabThink like an attacker to learn how to defend. Websites store a scrambled fingerprint of your password, called a hash. Attackers try common passwords until a fingerprint matches.
  3. 3Explore two-factor authenticationRead and investigateA password is one lock. Two-factor authentication adds a second, so a stolen password alone is not enough.
  4. 4Launch a Man-in-the-Middle attackTry it hereIn a man-in-the-middle attack, someone gets between you and the site you are talking to and reads or changes the messages. Play it out in a cafe on the network below.
  5. 5Explore social engineeringInvestigateSocial engineering means hacking people instead of computers: tricking someone into handing over a password, a code or access.
CryptoLab's Caesar Cipher panel: HELLO WORLD with shift 3 becomes KHOOR ZRUOG, and a two-ring letter wheel.
Each step shows how CryptoLab works, then opens it with a checklist that ticks as the work gets done.

Work on a computer. The apps need a keyboard and a bigger screen than a phone: a laptop, desktop or Chromebook. You can pay here and open the emailed link on the computer.
