2FA or Two-Factor Authentication is considered one of the best security features. However, this function could still be breached by hackers. Here’s how!
2FA is considered one of the most secured security features that could double-check your identity to make sure that you are the one accessing your file or account.
Google, Facebook, YouTube, and other online platforms are currently using Two-Factor Authentication or 2FA as their secondary security feature to protect user accounts. Of course, your password is still your number one security feature. But, when they are paired together, these functions could efficiently protect your account from hackers, scammers, and other online criminals.
What is Two-Factor Authentication?
2FA is a security feature that involves two different authentication factors, which are required so that the users can be verified by the system. This is one it is also called two-step verification or dual-factor authentication.
This advanced functionality was developed specifically to protect your sensitive credentials, as well as the resources that you could access. 2FA also offers a higher level of security compared to SFA or Single-Factor Authentication, another variant of authentication security feature.
2FA also relies on a user providing a password as the first step. After that, the security feature would proceed to the second step, which involves a combination of numbers, OTP (One-Time Password), facial scan, or fingerprint. Thanks to this process, Two-Factor Authentication adds an additional security layer that would make it harder for cybercriminals or hackers to breach your account and still personal information.
Although 2FA seems like an unbreachable security feature, cybersecurity experts confirmed that hackers could still use some advanced hacking campaigns or methods to bypass this functionality.
How Can Hackers Bypass Two-Factor Authentication?
Microsoft explained that 2FA uses SMS and voice calls, which could be open to different cybersecurity attacks. The giant tech firm added that since the security function still uses these methods, cybercriminals could easily acquire the codes used by Two-Factor Authentication.
The search engine giant also explained that the Two-Factor Authentication protection feature could also allow hackers to easily fool their victims into providing sensitive credentials themselves. Microsoft said that this could happen when the online attacker pretends to be the victim’s mobile service provider.
They could ask users to transfer their SIM to a device they prefer. This method is called SIM swapping, which is a proven hacking method to breach to protection layer. Aside from this, SMS-based one-time codes are also considered to be compromised through readily available tools by leveraging a hacking method called a reverse proxy. Once this campaign becomes successful, online criminals could facilitate communication between their victims and a service that they are impersonating or copying, allowing them to easily bypass the Two-Factor Authentication protection function.
As of the moment, hackers are usually breaching the Two-Factor Authentication of Android devices. Most of the Google-based smartphones and other gadgets rely on Two-Factor Authentication to protect their accounts and files. On the other hand, many individuals prefer relying on SMS instead of voice calls since they are annoyed by the sudden phone call. This is also the reason why hackers find it easy to breach the said protection layer.
