SIM swapping is one of the fastest-growing cyber threats, yet many people don’t understand how it works until it happens to them. In Episode 48 of Detonation Point presented by Elastio, Matt O’Neill sits down with Mark Kreitzman, general manager and co-founder of secure mobile carrier Efani, to explain how criminals exploit mobile devices, why your phone number has become a valuable target, and what you can do to better protect your digital identity.
What Is SIM Swapping?
Most people have experienced a legitimate SIM swap when upgrading to a new phone. Criminals use the same process but through social engineering, impersonation, or insider access to transfer your phone number to a device they control. Once they have your number, they can intercept text messages, reset passwords, and take over online accounts.
Why Your Phone Number Matters More Than Ever
Your phone number has become a gateway to your digital life. Many banks, email providers, and online services still rely on text message verification, making SIM swapping an effective way for criminals to bypass security measures. Mark explains why protecting your phone number has become just as important as protecting your passwords.
Practical Ways to Better Protect Yourself
Mark shares several simple habits that can significantly reduce your risk, including using separate email addresses for sensitive accounts, being cautious about where you share your email and phone number, and avoiding suspicious links, websites, and “free” online tools that collect personal information. He also discusses why relying solely on SMS-based two-factor authentication may no longer be enough.
A Different Approach to Mobile Security
After being SIM swapped himself, Mark co-founded Efani, a secure mobile carrier built to help prevent SIM swaps, account takeovers, and other mobile security threats. During the episode, he explains how Efani takes a security-first approach by adding multiple verification layers, encrypted global connectivity, and identity protections designed to reduce the risk of mobile-based attacks.
