This stealthy attack technique bypasses detection and can lead to full domain takeover. #BadSuccessor #dMSA #ActiveDirectorySecurity
Keypoints
- BadSuccessor exploits misconfigurations in Windows Server 2025’s dMSA feature to escalate privileges.
- Attackers can create rogue dMSAs and link them to privileged accounts like Administrator.

- Attacks are stealthy, often evading traditional detection systems within Active Directory environments.
- Mitigation strategies include restricting OU permissions and monitoring configuration changes in dMSA attributes.
