WRITEDAC Access on Active Directory Objectedit

Identifies the access on an object with WRITEDAC permissions. With the WRITEDAC permission, the user can perform a Write Discretionary Access Control List (WriteDACL) operation, which is used to modify the access control rules associated with a specific object within Active Directory. Attackers may abuse this privilege to grant themselves or other compromised accounts additional rights, ultimately compromising the target object, resulting in privilege escalation, lateral movement, and persistence.
