Verification Code Hijacking
An attack that intercepts or steals authentication codes to gain unauthorized access.
Understanding Verification Code Hijacking
Verification Code Hijacking is a cyberattack method where attackers steal one-time passwords (OTPs) or verification codes sent via SMS, email, or authentication apps. These codes are used in two-factor authentication (2FA) and account recovery processes, making them a valuable target for hackers.
How to Prevent Verification Code Hijacking
Avoid SMS-Based 2FA When Possible – Use authentication apps (Google Authenticator, Authy) or hardware security keys.
Enable SIM Lock & PIN – Protects against unauthorized SIM swaps.
Use Number Porting Protection – Some telecom providers offer security to prevent unauthorized SIM swaps.
Be Wary of Phishing Emails & Messages – Never share verification codes with anyone.
Enable Account Recovery Protections – Secure account recovery options to prevent unauthorized access.
Monitor Account Activity – Regularly check for unusual login attempts or account recovery requests.
Use Secure Password Managers – Reduces reliance on SMS or email-based verification.
Future of Verification Security
Passwordless Authentication – Adoption of FIDO2, WebAuthn, and biometric authentication instead of OTPs.
AI-Based Fraud Detection – Systems that detect and block suspicious login attempts in real-time.
Carrier-Level Security Enhancements – Telecom companies improving SIM swap protection.
Verification Code Hijacking remains a major cybersecurity risk. Switching to more secure authentication methods, staying alert to phishing attempts, and securing mobile accounts are critical to preventing such attacks.
