Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with high confidence (95%), supported by evidence indicating cVE-2024-21410 such as privilege escalation vulnerability in Exchange Server’s OWA component and Domain Policy Modification (T1484) with high confidence (90%), supported by evidence indicating successful exploitation grants attackers full control over the Active Directory domain. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate to high confidence (70%), supported by evidence indicating initial access—typically through stolen credentials.
