Abbott is proactively monitoring developments related to the recently identified vulnerabilities in third-party Bluetooth Low Energy (BLE) components, commonly referred to as “SweynTooth”. According to published reports, including the CISA Alert1, the vulnerabilities expose flaws in specific BLE components from multiple chip manufacturers that could allow an unauthorized user to interrupt BLE communication or bypass security.

Most Abbott products are unaffected by this advisory. For those products that do use the impacted BLE implementations, Abbott has thoroughly performed testing to determine whether there could be any potential impact on product performance and safety as a result of these vulnerabilities.

Abbott’s product security and quality teams are working closely with our chip suppliers to determine if any other devices that use BLE components similar to those named in the advisory could be affected. There are currently no known exploits of Abbott products related to SweynTooth.

Affected Products

Abbott is providing the list below to assist customers in identifying Abbott products that use BLE components potentially vulnerable to SweynTooth. The list below is subject to change based on updated information2 related to impacted BLE components, BLE manufacturer actions and additional product evaluation.





Confirm RxTM

Abbott has confirmed that Confirm RxTM is using one of the SweynTooth vulnerable components.

The vulnerability, if exploited, may temporarily interfere with the connection between Confirm Rx and the MyMerlin patient App or the Merlin PCS programmer.

No risk of patient impact: Abbott’s product is designed to automatically restore BLE communication if it is disrupted, and a temporary disruption in BLE communication does not impact the device’s ability to monitor for arrythmias.

There are no safety issues associated with the Confirm Rx device and no intervention is required.

Additional Information

Customers interested in additional information regarding patches, procedures or configuration changes on any Abbott products should contact their Abbott assigned account or customer support representative.

Abbott is committed to ensuring the safety and security our products. For more information on Abbott’s product cybersecurity program here.
