The departments of Homeland Security, Justice, and Health and Human Services have issued technical guidance summarizing existing “best practices” to prevent and respond to ransomware incidents – when cyber actors use malicious software to deny access to systems or data and demand a ransom payment. The fastest growing malware threat, ransomware can disrupt health care services and damage sensitive data beyond recovery, the guidance notes.
