The tale of pirates, treasure, and ciphers gripped my ten-year-old imagination and held me spellbound — sparking an interest in puzzles and codes that would later make computer science the obvious choice for my career.

Recently the Gold Bug returned to my thoughts while digging through a new bit of malware. Our
