MFA Fatigue Attacks
Multi-Factor Authentication (MFA) adds unparalleled security to your mail and network accounts. Microsoft reports that “MFA can block over 99.9% of account compromise attacks.” Most of our clients have implemented some level of MFA and we are working to protect 100% of them.
In response, the bad operators are using aggressive techniques to circumvent MFA. We have experienced firsthand MFA Fatigue Attacks. In this scam, cybercriminals barrage users with MFA authentication requests. They often strike late at night when users are asleep and not at their sharpest. Often the recipient will approve the request just to make the annoyance go away.
Unfortunately, blindly approving the authentication request can give hackers access to your email, contacts, calendar, SharePoint, and OneDrive data.
