This walkthrough demonstrates a complete Active Directory attack chain against the ignite.local lab using BloodyAD and Impacket, covering enumeration, privilege escalation, Kerberos attacks, credential dumping, RBCD, and persistence techniques. It highlights common misconfigurations—cleartext LDAP attributes, permissive ACLs, default machine account quotas, and disabled Kerberos pre-authentication—and provides detection and defensive recommendations. #BloodyAD #DCSync
Keypoints
- BloodyAD uses LDAP(S) and MS-SAMR to enumerate and modify AD objects from Linux without Windows tooling.
- The documented attack chain includes enumeration, Kerberoasting, AS-REP roasting, DCSync, RBCD, Shadow Credentials, and ACL abuse for escalation.
- Critical misconfigurations—cleartext passwords in LDAP attributes, GenericAll on Domain Admins, and default ms-DS-MachineAccountQuota—enable rapid domain compromise.
- Impacket tools (secretsdump, GetNPUsers, psexec) are used for credential dumping, ticket attacks, and remote execution to achieve full control.
- Recommended defenses include auditing AD ACLs, monitoring LDAP and replication events, enforcing strong SPN passwords and pre-authentication, deploying LAPS, and adopting a tiered administration model.
