Two-Factor Authentication (2FA) has been widely adopted as a more secure method for protecting accounts. However, with the continuous evolution of cyberattacks, hackers have discovered various ways to bypass this security layer. The article below will introduce five common methods hackers use to circumvent 2FA, helping you identify risks and better protect your accounts.
Common 2FA methods1. Phishing attacks: Man-in-the-Middle (MitM)
Typically, online connections are secured using protocols like Transport Layer Security (TLS) to keep information safe between users and servers. However, hackers can launch "Man-in-the-Middle" (MitM) attacks, especially when users connect to unsecured public Wi-Fi networks. By doing this, they can intercept information, including usernames and 2FA codes, allowing them to perform unauthorized actions on the user's account.
2. Tricking Users into Installing Malware
Hackers can also attack by directly installing malicious software on the user's browser. When victims log into services like online banking and use 2FA, the malware can silently operate to alter transactions without the user’s knowledge. Malware such as Carberp, Emotet, and Spyeye have been responsible for significant attacks using this method.
3. Attacks using social engineering techniques
Another common attack method is through social engineering. Hackers impersonate technical support staff, colleagues, or even authoritative organizations to gain the victim's trust and request their 2FA authentication codes. This method exploits human psychology by creating a sense of urgency or trust, tricking the victim into providing the necessary information.
4. SIM Swapping
Hackers can use the "SIM swapping" technique to take control of a victim's phone number. By impersonating the user, they can request the telecom provider to transfer the victim's number to a new SIM card under the hacker’s control. Once this is done, they receive the OTP (One-Time Password) sent to that phone number, giving them easy access to the victim's online accounts.
5. Stealing authentication cookies
Some services allow users to authenticate with Two-Factor Authentication (2FA) only during the first login, storing this information through cookies in the browser. If hackers manage to steal these cookies, they can use them to log into the victim's account without needing to re-enter the authentication code. While storing login cookies is convenient, it poses significant risks if not properly secured.
Enhanced security solutions with YubiKey
While Two-Factor Authentication (2FA) provides strong protection, methods like OTP via phone or authentication apps can still be vulnerable to sophisticated attack forms. To optimally protect your accounts, consider using YubiKey—a physical security key developed by Yubico that offers Two-Factor Authentication.
YubiKey requires physical authentication each time you log in, completely eliminating the risk of phishing attacks or cookie theft. With the capability to work across various online services, from Google and Facebook to financial systems, YubiKey ensures superior security levels for users.
