The Sizable Risk of Cyber Well-being in Healthcare by Vectra AI Security Research team

This report analyzes healthcare cybersecurity during early COVID-19, finding that while WHO reported increased phishing and ransomware, Vectra’s telemetry showed the overall attack landscape remained similar to 2019, with observed spikes in external data movement largely driven by accelerated cloud migration and telemedicine. It highlights heightened risks from unmanaged medical IoT and cloud services, noting increases in behaviors like large data transfers and “data smuggling” that can resemble exfiltration, and warns that the convergence of IoT and cloud exposure could precipitate a broader cyber risk scenario for healthcare.
