Researchers Crack Microsoft Azure MFA in an Hour, Rainbow Secure to the rescue.

A critical flaw in the Microsoft Azure MFA’s rate limit for failed sign-in attempts allowed unauthorized access to a user account, including Outlook emails, OneDrive files, Teams chats, Azure Cloud, and more.?

How researchers cracked Microsoft Azure MFA?

Researchers cracked a Microsoft Azure method for multifactor authentication (MFA) in about an hour, due to a critical vulnerability that allowed them unauthorized access to a user's account, including Outlook emails, OneDrive files, Teams chats, Azure Cloud, and more.? Researchers at reputed security firm discovered the flaw, which was present due to a lack of rate limit for the number of times someone could attempt to sign in with MFA and fail when trying to access an account. The flaw exposed the more than 400 million paid Microsoft 365 seats to potential account takeover.?

The researchers achieved the bypass, by rapidly creating new sessions and enumerating codes. This allowed them to demonstrate a very high rate of attempts that would quickly exhaust the total number of options for a 6-digit code, which is 1 million.?

This way one could execute many attempts simultaneously. During the multiple failed attempts to sign in, account owners did not receive any alert about the activity, making this vulnerability and attack technique dangerously low profile.?

Rainbow Secure to the rescue

Rainbow Secure team very early discovered the flaws of traditional keyboard-based password technique and introduced interactive graphical credentials to secure the front door to digital world.?

Rainbow Secure MFA secures first and second level of user authentication with multiple layers of security including graphical attributes like color and font styles, device and session context and location. This brute-force and phishing resistant authentication solution protects from account take over attacks with reduced business cyber liability from stolen credentials.?

Rainbow Secure login solutions naturally provide rate limiting to all types of user authentication methods (password, MFA, OTP, QR code, Biometrics) due to its inherent graphical login steps.

You can still use any app authenticator solution while Rainbow Secure provides overall login security and secures you from such MFA flaws and traditional login password weaknesses.?
