The Splunk Threat Research Team recently developed a new analytic story, Active Directory Kerberos Attacks, to help security operations center (SOC) analysts detect adversaries abusing the Kerberos protocol to attack Windows Active Directory (AD) environments. In this blog post, we’ll describe some of the detection opportunities available to cyber defenders and highlight analytics from the analytic story.
The FSMO (Flexible Single Master Operations) roles are vital when it comes to Active Directory. The FSMO roles help keep Active Directory consistent among all of the domain controllers in a forest by allowing only specific domain controllers to perform certain operations. Additionally, Active Directory FSMO Roles are essential for your Active Directory environment’s stability and security.
Microsoft released a valuable new Azure feature in December of 2021: custom security attributes. This feature is still in preview.

Microsoft recently published two critical CVEs related to Active Directory (CVE-2021-42278 and CVE-2021-42287), which when combined by a malicious actor could lead to privilege escalation with a direct path to a compromised domain. In mid-December 2021, a public exploit that combined these two Microsoft Active Directory design flaws (referred also as “noPac”) was released.
