Case Study: a large healthcare system recovers from ransomware attack with Semperis

Large healthcare system partners with Semperis to recover from ransomware attack

A large healthcare system in the US partnered with Semperis to combat a ransomware attack after adversaries exploited their Active Directory for reconnaissance, lateral movement, and privilege escalation. This exploitation provided the attackers with persistence and wide access across their network.

Semperis utilized its Purple Knight tool to discover the specific Active Directory weaknesses that had been exploited. The solution enabled the healthcare system to detect the vulnerabilities, execute steps to remove them, and establish a more secure posture to protect against future attacks.
