An external researcher has identified vulnerabilities in the Medtronic MyCareLink™ Patient Monitor (model numbers 24950 and 24952). This product is a remote monitoring system for patients with Medtronic implantable cardiac devices that allows patients to transmit device data to the Medtronic CareLink™ Network via a cellular connection for viewing by clinicians.

The vulnerabilities identified may allow a highly skilled person with physical access to a MyCareLink Patient Monitor to extract per-product credentials (credentials that are unique to each specific monitor) and potentially upload invalid data to the Medtronic CareLink Network. After assessing the impact of the vulnerabilities on patient safety, we have determined that the risks are controlled (meaning there is sufficiently low [acceptable] residual risk of patient harm).

These vulnerabilities do not allow modification of patient health information or existing data on the CareLink Network. There are no known reports of data being impacted or targeted by the identified vulnerabilities.


Medtronic is increasing the level of authentication required to upload data from the MyCareLink Patient Monitor to the Medtronic CareLink Network. In addition, increased cybersecurity monitoring has been implemented to detect and respond to any potential attempts to upload invalid data.

Medtronic encourages patients to only use home monitors obtained directly from Medtronic or their clinician. Patients should not use a pre-owned MyCareLink Patient Monitor or one that is purchased secondhand or online. Monitors obtained through unofficial means are at an increased risk for exploitation associated with the vulnerabilities identified.

At Medtronic, nothing is more important to us than the safety of our patients. We believe that the therapeutic benefits of our products far outweigh potential security risks, and we actively review our security practices to mitigate risks during premarket development and post-market use.
