What is SIM Swap and Why Is It Dangerous?

A SIM swap attack occurs when cybercriminals trick your mobile service provider, or use insiders, to transfer your phone number to a new SIM card that they control. With your number in their possession, hackers can gain access to your private accounts, including email, social media, crypto, business accounts, and even bank accounts. This allows them to reset passwords and potentially steal sensitive data, causing financial loss, identity theft, and privacy breaches.

Why Should You Care About SIM Swap Protection?

SIM swap attacks have become more prevalent in recent years. Hackers can target anyone, but those with high-profile jobs, large social media followings, or significant online financial activity are particularly vulnerable. Moreover, SIM swap attacks are challenging to detect and can take place quickly, making them even more dangerous.  When you are the victim of a SIM swap attack, you lose your mobile service which means you need to find another way of contacting your carrier to report an attack has occurred.  The longer the delay in reporting and verifying yourself to the carrier means that hackers have time to dig deeper into your proprietary accounts.Here are some key reasons why protecting your phone number is crucial:

- Loss of Control Over Accounts: Once hackers gain control of your phone number, they can access accounts that use your phone number for verification, such as banking or email accounts.

- Financial Loss: With access to sensitive financial data, hackers can make unauthorized transactions or even steal your identity.

- Privacy Breach: Personal information, photos, and messages stored on your phone can be accessed and exploited by attackers.

How to Protect Your Phone Number from SIM Swap Attacks

After using Efani’s NumberScan tool, here are some essential steps you can take to secure your phone number:

  4. Use an encrypted email service such as proton, and use separate emails for personal, business and crypto accounts.
  5. Monitor Your Accounts: Regularly check your accounts for any unauthorized access or suspicious activity.
