As digital security measures advance, so do cybercriminals‘ tactics. One of the emerging threats is a sophisticated type of phishing known as authentication-in-the-middle attacks. Despite the increased security provided by multi-factor authentication (MFA), scammers can easily phish your MFA codes using tools such as evilginx2, Modlishka, and EvilnoVNC. These are all phishing kits that have templates for popular services such as Okta®, Microsoft 365® (“M365”), Google Workspace, and others. This article explains how to protect yourself and your clients or patients.

Understanding Authentication-in-the-Middle Attacks

Authentication-in-the-middle attacks are a new variation of phishing attacks, resembling the well-known man-in-the-middle (MitM) attacks. In this scenario, a user is tricked into visiting a phishing site disguised as a legitimate website they frequently use, such as a bank, email provider, or social media platform.

Once the user enters their login credentials into the fake site, the attackers capture this information and immediately relay it to the legitimate site in real time. The user is then prompted to complete the MFA step, typically by entering a code or accepting a push notification. The attackers also intercept this MFA information, allowing them full access to the user’s account. Once inside, scammers can alter account settings or steal sensitive information.

How Scammers Exploit Multi-Factor Authentication

Scammers can easily phish your multi-factor authentication codes. Here’s how the process works:

1. Luring Victims. Attackers often lure victims to phishing sites through links embedded in emails, social media messages, or even sponsored search results. These links can be difficult to distinguish from legitimate ones.
2. Capturing Credentials. When victims enter their credentials on the fake site, scammers capture and use these details to log into the real site.
3. Intercepting MFA Codes. During the MFA process, the entered code or push notification approval is intercepted, granting the attacker access.

Preventing Authentication-in-the-Middle Attacks

To safeguard against these sophisticated attacks, consider the following strategies:

1. Stay Vigilant. Awareness is the first line of defense. Be skeptical of unsolicited links and verify the legitimacy of websites before entering any credentials. Trust your instincts if something seems suspicious.
2. Use Security Software. Reliable security software can block many phishing sites. They help protect against such threats by identifying and blocking known phishing domains.
3. Utilize a Password Manager. Password managers enhance security by auto-filling credentials only on legitimate sites. This process reduces the risk of inadvertently entering information on a phishing site.
4. Consider Passkeys. Passkeys are an easier and more secure alternative to passwords. They let you sign-in with just your fingerprint, face scan, or screen lock. Unlike traditional MFA methods, passkeys offer a more secure alternative that cannot be intercepted in the same way. As passkey adoption increases, they present a robust defense against authentication-in-the-middle attacks.
5. Regularly Monitor Accounts. Frequently check your credit card and other accounts for unauthorized activity. Immediate detection can minimize potential damage. Report any suspicious activity to your bank immediately. Shut down unneeded accounts.

Conclusion

Scammers can easily phish your multi-factor authentication codes. Avoid associated problems by staying informed, using robust security tools, and considering advanced authentication methods like passkeys. By implementing these precautions, behavioral professionals and their clients can better protect their sensitive information from emerging phishing threats.
