Windows AD Same Domain SID History Addition

This analytic detects changes to the sIDHistory attribute of user or computer objects within the same domain. It leverages Windows Security Event Codes 4738 (User Account Changed) and 4742 (Computer Account Changed) to identify when the sIDHistory attribute is modified. This activity is significant because the sIDHistory attribute can be abused by adversaries to grant unauthorized access by inheriting permissions from another account. If confirmed malicious, this could allow attackers to maintain persistent access or escalate privileges within the domain, posing a severe security risk. The rule specifically looks for cases where the added SID History matches the target SID or target domain name, indicating an attempt to add a SID from the same domain.
