Oasis Security Research Team Discovers Microsoft Azure MFA Bypass
Oasis Security Research Team Discovers Microsoft Azure MFA Bypass

Microsoft has more than 400 million paid Office 365 seats, making the consequences of this vulnerability far-reaching. The bypass was simple: it took around an hour to execute, required no user interaction and did not generate any notification or provide the account holder with any indication of trouble.
