Understanding SIM Swap

SIM swap fraud* occurs when an attacker impersonates you to transfer your phone number to a new SIM card. This gives them access to any accounts linked to that number, including bank accounts and social media profiles, allowing them to perform unauthorized transactions or steal your identity.

Preventative Measures

There are several steps you can take to minimize the risk of being a victim of SIM swap attacks.

Use Two-Factor Authentication (2FA)

• Enable two-factor authentication on all accounts that offer it, using an authentication app instead of SMS. Apps like Authy or Google Authenticator provide an extra layer of security by not relying on your phone number for account verification.
• Avoid using phone numbers for recovery options whenever possible.

Keep Personal Information Secure

• Be mindful about sharing personal information online; protect your data from social media scammers. Reduce the amount of personal data visible on your profiles.
• Set complex, unique passwords for each account and update them regularly.
• Consider freezing your credit to add a layer of security to your financial activities.

Monitor Your Accounts Regularly

• Regular check-ins on your financial and online accounts can help identify unauthorized activity quickly. Report any suspicious activity to your service provider immediately.
• Enable account alerts for transactions and login attempts.
