How a SIM Swap Triggered a $390M Cyber Attack at Marks & Spencer

A single phone number can become the weakest link in your entire security setup.

In this video, we break down how a SIM swap attack can escalate into a full-scale corporate breach, leading to massive financial loss and operational disruption. What starts as control over a phone number can quickly turn into access to emails, accounts, internal systems, and ultimately, millions of dollars at risk.

This is not just a technical issue. It is a real-world threat affecting businesses, executives, and individuals who rely on their phone number as a primary layer of security.

What you’ll learn:

- What a SIM swap attack actually is
- How attackers take control of a phone number
- How this leads to account takeovers and data breaches
- Why traditional carriers fail to stop these attacks
- What real protection looks like

If your phone number is tied to your bank accounts, crypto, email, or business systems, this is a risk you cannot ignore.
