Risk evaluation
Successful exploitation of these vulnerabilities together could result in the attacker being able to modify or fabricate data from the implanted cardiac device being uploaded to the CareLink Network and remotely execute code on the MCL Smart Patient Reader device, which could allow control of a paired cardiac device. The exploitation must be initiated within Bluetooth signal proximity of the vulnerable product. Medtronic is currently unaware of any cyberattack, privacy breach, or patient harm as a result of these vulnerabilities.
Critical infrastructure sectors

Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage onus-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
Exploitability
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
