⚠️ Note: BloodHound doesn't currently have all elements required for a full BadSuccessor audit, namely 'Create msDS-DelegatedManagedServiceAccount', 'Create all child objects', & dMSA nodes. For that, you should run Get-BadSuccessorOUPermissions.ps1 shared in Yuval's blog.

BadSuccessor: Abusing dMSA to Escalate Privileges in Active Directory
The Reddit post discusses a method called BadSuccessor that exploits the dMSA (delegated Machine Service Account) to perform privilege escalation in Active Directory. This technique allows an attacker to compromise a dMSA account and gain elevated privileges, which can pose significant security risks for Active Directory environments.
