Multi-Factor Authentication not very secure

If you thought you were safe because you use multi-factor authentication (MFA), there is bad news for you: MFA can be broken.
While MFA is still a recommended practice and is much safer than having just a password, it does not, however, guarantee your safety. You cannot afford to be complacent.

FBI: MFA Not So Secure!

Last month, the FBI issued a warning to private companies about MFA. The agency said that there is a rising threat of attacks against organizations and their employees that can bypass MFA solutions.

There are multiple ways to work around MFAs:

  • For example, like how the Twitter account of Jack Dorsey was hacked, your SIM too can be swapped.
  • Or if the site using MFA is not securely developed, an attacker can bypass MFA anyway and get at your private data. 
  • Finally, the ubiquitous ‘social engineering attacks’ can get you to divulge your information to an attacker voluntarily enabling them to inject themselves into the MFA cycle.

I do not want you to panic unnecessarily – after all, the FBI still says “Multifactor authentication continues to be a strong and effective security measure to protect online accounts, as long as users take precautions to ensure they do not fall victim to these attacks, …”.  I would only ask you to make note of the caveat.
