CyberFirst Girls Competition & Cracking Codes

It was an honour to support two teams of Year 8 students to take part in the CyberFirst Girls Competition run by the National Cyber Security Centre. The girls were at the very youngest end of the age range and figured out everything from how to geolocate a photo, read Base64 messages, sniff packets and a whole lot more.

Following on from a week of intensive code cracking through lunchtimes, we had a go at some Python to investigate Caesar’s Cipher. We sent messages to each other and then changed the code to brute force attack the code – making our programs print out every possible outcome so we could spot the decrypted message.
