@Zamester is a 12-year-old middle-school student who likes writing secret messages using ciphers and solving puzzles. @Krypton3 is the 9-year-old who decode his brother’s secret messages. They both like to read, and re-read, the Harry Potter books. @Kryton3 first used Harry Potter to explain good password security, and @Zamester found the transposition cipher. They both attended R00tz Asylum at DEFCON and had a great time learning about penetration testing and lock-picking. They hope to go to more conferences and events to learn more about information security.
