Defeating Ransomware, How a Small, Midwestern University Defeated Ransomware Adversaries



With no dedicated cybersecurity personnel, a small IT staff and limited resources, a small university fought back against adversaries who attempted a wide scale ransomware attack.  This is a play-by-play recounting of the events as they occurred, the security controls that were in place before the attack and the actions taken to stop the attack and expel the attackers from the university network.
