MFA is Not a Guarantee of Cyber-Safety, Here’s How MFA is Hacked

Multi-factor authentication (MFA) is a technology that offers an extra layer of security to online accounts. The idea behind MFA is to add another authentication factor beyond the traditional username and password combination, making it substantially harder for hackers to gain access to your accounts. However, like any security technology, MFA isn’t perfect, and it can still be subject to hacking. In this article, we’ll look at some of the ways that MFA can be hacked.
One way that MFA can be hacked is through phishing attacks. Phishing attacks refer to a method used by attackers to trick you into providing your login credentials. One common example is when you receive an email or text message from a seemingly legitimate source, such as your bank or other financial institution, that prompts you to enter your login credentials. If you are unaware that this is a phishing scam, you may enter your username and password, giving the attacker access to your account. In some cases, the attacker may even ask for a one-time code that you need to enter to complete the login, allowing them to bypass the MFA security.
Another way that MFA can be vulnerable is through the use of public Wi-Fi networks. Public Wi-Fi networks can be accessed by anybody, making them a prime target for attackers. If you log in to your bank account or other sensitive accounts using public Wi-Fi, hackers can intercept your login credentials and use them to gain access to your accounts. In this case, MFA may not be useful as the attacker has already gained access to your login credentials.
Hackers can also try to bypass MFA by gaining access to your device or computer. If they can access your device, they may be able to view your verification code or fingerprint scan, allowing them to log in to your account. This type of attack is less common because it requires physical access to your device or computer, but it’s still worth being aware of.
Another potential vulnerability with MFA is the verification code. In some cases, the verification code may be sent via SMS, making them vulnerable to SIM-swapping attacks. SIM swapping refers to a technique used by attackers to trick your cellular provider into associating your phone number with a new SIM card. If the attacker is successful, they can receive your verification code, allowing them to bypass MFA entirely.
Finally, attackers can use brute force attacks to bypass MFA. Brute force attacks refer to a technique used by hackers to attempt to guess your password. This can lead to “MFA fatigue” where a user is frustrated from the constant request from the MFA push app on their phone, and just accepts it to make the phone stop bothering them.
In conclusion, MFA can be hacked in several ways, even though it offers a substantial level of protection for your online accounts. To stay safe, It is always essential to take a multi-pronged approach to your online security. Always be wary of phishing scams, monitor your accounts regularly, and avoid using public Wi-Fi whenever possible. Additionally, use a strong, unique password for each account, use biometric authentication if possible, and enable push notifications with authentication apps to provide an extra layer of security.
