Healthcare & Medical Device Security

Medical devices — infusion pumps, patient monitors, ventilators, and imaging systems — run embedded firmware that directly impacts patient safety. FDA has reported 150+ cybersecurity advisories for medical devices since 2018. Hardcoded credentials, unencrypted HL7/DICOM traffic, and legacy OS components create life-threatening attack surfaces.

Medical Device Threat Landscape

Healthcare is the most targeted sector for ransomware, with connected medical devices serving as entry points. Infusion pumps with hardcoded credentials allow attackers to modify drug dosages remotely. Patient monitors transmitting vitals over unencrypted MQTT/HL7 enable data interception. DICOM imaging servers running decades-old C++ parsers are vulnerable to memory corruption. The average medical device takes 6-12 months to patch due to FDA regulatory requirements.

Regulatory Requirements (FDA, MDR, IEC 62443)

The FDA now requires a cybersecurity Software Bill of Materials (SBOM) for all new device submissions. The EU Medical Device Regulation (MDR) mandates cybersecurity risk assessment. IEC 62443 provides industrial cybersecurity standards applicable to connected medical devices. Manufacturers must demonstrate secure-by-design principles including threat modeling, secure boot, and encrypted communications.

How Precogs AI Secures Medical Devices

Precogs AI analyzes medical device firmware to detect hardcoded credentials in embedded web servers, identify unencrypted protocol usage (HL7v2, DICOM without TLS), verify secure boot chain integrity, detect memory corruption vulnerabilities in DICOM/HL7 parsers, and generate the SBOM required for FDA premarket submissions.

Attack Scenario: The Hospital Ransomware Pivot via IoMT

An attacker sends a phishing email to hospital staff, gaining a foothold on the administrative network.

They scan the network and discover hundreds of connected medical devices (Internet of Medical Things) on the same VLAN.

They find an infusion pump management server with default credentials (admin/admin) exposed on port 443.

Through the management server, they push a modified drug library to all connected infusion pumps, demonstrating patient safety impact.

They deploy ransomware across the hospital network, demanding payment to restore access. The FDA advisory takes months to issue, leaving thousands of similar devices vulnerable worldwide.

Real-World Code Examples

Hardcoded Credentials in Infusion Pump (CWE-798)

Medical device manufacturers frequently embed hardcoded service credentials in firmware for maintenance access. These credentials cannot be changed by hospital IT staff, are shared across every device of the same model, and are often discoverable through firmware extraction. An attacker with these credentials can modify drug dosage libraries in infusion pumps.

VULNERABLE PATTERN

// VULNERABLE: Extracted from decompiled infusion pump firmware (ARM)
// Embedded web server for clinical configuration
int authenticate_nurse(char* username, char* password) {
    // Hardcoded service account — cannot be changed by hospital IT
    if (strcmp(username, "biomedadmin") == 0 &&
        strcmp(password, "pump2019!") == 0) {
        return AUTH_SUCCESS;  // Full admin access to drug library
    }
    return check_ldap(username, password);
}

SECURE FIX

// SAFE: Certificate-based authentication with no hardcoded credentials
int authenticate_nurse(X509_CERT* client_cert) {
    // Verify client certificate against hospital CA
    if (!verify_certificate_chain(client_cert, hospital_ca)) {
        return AUTH_FAILURE;
    }
    // Extract role from certificate attributes
    char* role = get_cert_attribute(client_cert, "ou");
    return authorize_role(role);
}

Detection & Prevention Checklist

✓Extract firmware from medical devices and scan for hardcoded credentials using entropy analysis and string extraction
✓Verify that all clinical data protocols (HL7v2, DICOM, FHIR) are encrypted with TLS 1.2+ on the wire
✓Audit medical device network segmentation — IoMT devices should be on isolated VLANs with strict firewall rules
✓Generate SBOMs for all medical device firmware components to meet FDA premarket cybersecurity requirements
✓Test DICOM and HL7 parsers with fuzzed inputs to detect memory corruption vulnerabilities in clinical data handling
