Background on Two Factor Authentication
Two-factor authentication (2FA) adds an extra layer of security to your online accounts. It requires you to provide two different authentication factors to verify your identity, typically something you know (like a password) and something you have (like a mobile device).
The Role of SMS in Authentication
SMS-based 2FA has been a popular method for years. When you log in, you receive a text message with a one-time code. You enter this code to complete the login process.
This method is widely accessible since most people have mobile phones. It’s easy to implement for businesses and familiar to users.
However, SMS-based 2FA has vulnerabilities that hackers can exploit. Cybercriminals can intercept text messages through various techniques, including SIM swapping or exploiting weaknesses in cellular networks.
The FBI recommends using more secure 2FA methods, such as authenticator apps or hardware tokens, instead of SMS.
Advantages of Two Factor Authentication
2FA significantly enhances your account security. Even if a hacker obtains your password, they can’t access your account without the second factor.
It protects against:
- Credential stuffing attacks
- Phishing attempts
- Password breaches
Using authenticator apps is more secure than SMS-based 2FA. These apps generate time-based one-time passwords (TOTP) that change every 30 seconds.
2FA also helps businesses comply with data protection regulations and demonstrates a commitment to user security. While no security measure is perfect, 2FA makes it much harder for unauthorized users to access your accounts.

Rise in SMS Interception Incidents
Recent hacking cases have exposed vulnerabilities in SMS-based two-factor authentication. Cybercriminals are employing sophisticated methods to intercept text messages containing security codes.
Recent Hacking Cases
In December 2024, the FBI revealed a massive telecom breach that compromised non-encrypted messages. This incident allowed hackers to intercept one-time passcodes sent via text for two-factor authentication.
The breach was attributed to hackers aligned with the Chinese government, who infiltrated U.S. telecommunications infrastructure. Their deep access enabled them to monitor unencrypted communications of numerous individuals.
In response, federal agencies issued warnings about the risks of using SMS for authentication. They urged users to switch to more secure methods to protect their accounts and sensitive information.
Methods Used by Hackers
Cybercriminals employ various techniques to intercept SMS messages containing authentication codes:
- SIM swapping: Hackers trick mobile carriers into transferring your phone number to a new SIM card they control.
