Definition and Overview

SIM Swapping is a fraudulent activity where attackers transfer your phone number to a new SIM card to gain access to your sensitive data. This technique exploits weak security measures in mobile networks and can lead to severe consequences such as unauthorized access to your bank accounts and personal emails.

• Commonly used by hackers to bypass Two-Factor Authentication (2FA).
• Can affect anyone with a mobile phone number.
• It’s a growing threat due to the heavy reliance on mobile phones for both personal and financial uses.

Process of SIM Swapping

Understanding how SIM Swapping works involves several steps executed by the hacker:

1. Reconnaissance: Attackers gather personal data usually through phishing.
2. Contact Telecom Provider: They impersonate the victim and request a SIM swap.
3. Verification and Execution: Using stolen personal information, they convince the provider to transfer the number to their SIM.
4. Completion: The victim loses service while the attacker gains control.

It’s crucial to recognize that weak or compromised verification processes can make this swap successful.
