Mark explains how SIM swapping works, why your mobile number has become the master key to your digital identity, and how attackers use social engineering to bypass traditional security measures. He also shares real-world examples of high-profile SIM swap attacks, discusses the growing impact of AI-driven scams, and offers practical steps anyone can take to better protect their personal information.
