Abusing Azure AD pass-through authentication vulnerabilities

In May 2022, Secureworks Counter Threat Unit (CTU) researcher found multiple vulnerabilities in one of the Microsoft Azure Active Directory (Azure AD) authentication methods, Pass-through Authentication (PTA). These flaws allow threat actors to gain persistent and undetected access to the target organisation, impersonate users, gather credentials, and perform Denial of Service (DoS) attacks remotely. Microsoft has categorised these vulnerabilities as by-design.

In this talk, we will cover the details of the flaws and show how they can be exploited in action. We will also show how to harden your environment to protect against PTA attacks and detect whether your environment has been compromised.
