Hospital Ransomware Attack: Network Segmentation Defense

Interactive 3D hospital network graph: watch a ransomware infection spread from a phishing email through unpatched administrative workstations, patient-data servers and connected medical devices, then compare a flat network against a segmented one.

Cybersecurity3DModerate60 FPS

This simulator visualizes how ransomware spreads through a hospital's internal network — administrative workstations, patient-record servers and connected medical devices such as infusion pumps, patient monitors and an MRI scanner. Infection enters through a phishing email on a front-desk PC and then hops along network links to reachable neighbors, spreading faster to devices that haven't been patched. Toggle between a flat network, where nothing stops the infection from reaching every device, and a segmented network, where a firewall boundary isolates the medical-device segment and stops the spread at the edge.

⚙ Under the hood

3D graph of a hospital network: workstations, patient-data servers and connected medical devices (infusion pumps, monitors, an MRI scanner). Trigger a phishing-borne ransomware infection and watch it spread node to node through unpatched devices, then compare a flat network against a segmented one where a firewall boundary stops the spread at the medical-device segment.
