3.4 RESEARCHER

These vulnerabilities were first reported to GE Healthcare by researchers Marc Ruef and Rocco Gagliardi of scip AG. Additional reports were provided to GE Healthcare by Michael Aguilar of Secureworks and Jonathan Bouman of Protozoan.nl and Andrea Palanca and Gabriele Quagliarella of Nozomi Networks.

4. MITIGATIONS

GE Healthcare recommends organizations restrict physical access to devices by unauthorized individuals. Additionally, where available, GE Healthcare recommends users enable the "system lock" password in the Administration GUI menu if possible. This will require a password to be entered before the system can be accessed. The ‘system lock' would limit non-authenticated users from accessing the application.

GE Healthcare recommends that users with questions reach out to a GE Healthcare service representative and users with an active support account visit the GE Healthcare product security portal (login required).

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

• Ensure there is physical protections in place to prevent the devices from any unauthorized access.
• Encourage security awareness throughout the hospital staff to ensure clinical staff will report any unauthorized person trying to login or otherwise tamper with a medical device.
• Educate employees on social engineering, both online and in-person/on-site. This is often used to gain confidence to unauthorized resources.
• Where additional information is needed, refer to existing cybersecurity in medical device guidance issued by the FDA.

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 on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely.
