My name is Scotty. My foray into cybersecurity wasn't your typical journey—it started in my teen years, driven by curiosity and a bit of mischief bypassing school internet filters. Early experiments with phreaking, using a Psion Revo for free phone calls, were just the beginning of a lifelong passion for cracking digital security puzzles.

Leaving office life behind, I ventured into the British Army as an Electronic Warfare Systems Operator, focusing on disrupting enemy communications. It was a thrilling phase where I honed my skills under pressure.

My expertise took on a new level in Cyprus, mentoring on two groundbreaking cyber capabilities—details of which are, of course, classified.

Transitioning to the private sector, I've immersed myself in teaching and developing cybersecurity products. From infrastructure and web app security to WiFi, cloud, and malware analysis, I've led the design of government cyber competitions, blending challenge with education.

Having the privilege to teach at premier conferences like Blackhat and Nullcon, I now freelance, bringing my blend of hands-on experience and contemporary practices to the forefront of cybersecurity education.

With that trumpet blowing out of the way, let's begin to explore steganography in our next section: Introduction to Steganography.
