With little information known at this time, all that can be done is to brief employees on the dangers of ransomware and also teach them how to spot phishing scams and other tactics that attackers use to gain access to business servers. Attackers targeting medical facilities with ransomware has been an increasing trend in recent months. It is likely that attackers believe time-sensitive critical services, including healthcare, will pay high ransom demands to get back to normal operations quickly. It is important for any critical service to have a continuity of operations plan that includes maintaining offline backups, an incident response plan to contain the spread of malware, and the ability to request outside assistance from government agencies in the event of a major incident to speed recovery and restoration of service. Managed security services such as Binary Defense also have an important role in detecting and quickly responding to computer intrusions, keeping a minor incident from spreading to more computers and becoming a major problem.
