Hospitals represent prime targets for extortion ransomware. When malware compromises active directory domains, lateral movement spreads rapidly to unpatched bedside devices running embedded operating systems. This research proposes strict application-layer protocol whitelisting and stateless proxying to render medical devices impervious to network-borne payload delivery.
Wormable exploits exploit SMB and RDP vulnerabilities to pivot across flat hospital subnets. Medical monitors sharing VLANs with administrative workstations are easily compromised, leading to denial-of-service in critical care wings.
By enforcing that only valid, schema-conforming HL7 and FHIR payloads pass through the gateway, arbitrary binary exploits and shellcodes are rejected at the edge without reaching medical endpoints.
