Attackers Pose as IT Support on Microsoft Teams, Abuse AD CS to Steal Company Data
Summary
Attackers have been impersonating IT support personnel on Microsoft Teams to trick employees into granting them remote access to their computers. Once access is obtained, the attackers exploit misconfigured Active Directory Certificate Services (AD CS) to steal credentials and obtain digital certificates for privileged accounts, including domain controllers.
IFF Assessment
This attack leverages social engineering and Active Directory misconfigurations to gain privileged access, posing a significant threat to organizational security.
Defender Context
This attack highlights the dual threat of social engineering combined with infrastructure misconfigurations. Defenders must focus on user education regarding suspicious requests and implement stricter controls and auditing for Active Directory Certificate Services to prevent privilege escalation.
