What is a SIM Swap Attack?

A SIM swap attack is when fraudsters hijack your mobile phone number by convincing your mobile service provider to transfer your number to a new SIM card in their possession. With control over your phone number, these attackers can access accounts secured through SMS-based two-factor authentication (2FA).

Why are SIM Swap Attacks Dangerous?

SIM swap attacks pose numerous threats due to their ability to bypass standard account security measures. Once they control your phone number, attackers can:

• Access banking, email, and social media accounts by resetting passwords.
• Steal personal information for identity theft purposes.
• Commit financial fraud by making unauthorized transactions.

Preventive Measures Against SIM Swap Attacks

Enhance Your Account Security

Start by strengthening your account security using multiple layers of protection.

• Avoid using SMS-based 2FA; instead, opt for app-based authentication like Google Authenticator or Authy.
• Set up a strong, unique password for all your accounts.
• Use a password manager to keep track of complex passwords and ensure they remain secure.

Stay Alert

Being proactive can help you catch potential attacks early.

• Watch for suspicious activity on your phone, such as losing signal unexpectedly.
• Monitor your bank and online account statements regularly for unusual transactions.
• Be wary of phishing emails or calls asking for personal information.

What to Do If You Suspect a SIM Swap Attack

Act quickly if you suspect your number has been transferred without your consent.

• Contact your mobile service provider immediately to cancel the fraudulent transfer and recover your phone number.
• Change all your account passwords and secure your email accounts first.
• Notify your bank and any other important services connected to your phone number.
