Attacking and Defending Hybrid Active Directory Environments


Organizations have moved to the cloud and are also extending their Identity platforms to cloud. Active directory is increasingly being integrated with Azure Active directory creating a scalable Identity platform often referred to as Hybrid Active Directory.

While this approach helps organizations to integrate their existing identity platform with the cloud, this also increases the attack surface and provides attackers opportunities to move between environments, launch new attacks and maintain long term covert persistence.

Through our experience of performing Incident response, cloud and AD security assessments we have seen some of these techniques being used by the threat actors.

In this talk we will share some of the techniques attackers use to target hybrid active directory and look at ways of how defenders can defend against and hunt for these techniques.
