Medtronic monitors and devices send data unencrypted

CVE-2019-6540 · published 7 years ago
Summary

The telemetry connection used by Medtronic MyCareLink monitors and several related implanted devices does not encrypt the information it transmits. Someone standing close enough to the device could intercept and read that data, including personal health details. Apply any available firmware updates from Medtronic and keep the devices in physically secure locations to reduce the risk.
