Merlin@home: What’s the Problem?

The Merlin@home transmitter works in conjunction with St. Jude’s data management system, the Patient Care Network, to remotely transmit patient data from an implantable cardiac device to a physician’s office. St. Jude has distributed hundreds of thousands of implantable cardiac devices that rely on remote monitoring via the Merlin system. Used Merlin@home monitors can also be found on eBay for as little as $35.00.

In August 2016, the Muddy Waters investment group announced that it had taken a short position in St. Jude stock, which would allow the group to benefit financially if the company’s share price declines. In a 33-page report, Muddy Waters said that it expect this would occur due to alleged cybersecurity issues that make St. Jude’s implantable cardiac devices susceptible to hacking, especially those bundled with the  Merlin@home transmitter system. Demonstrations conducted by a cybersecurity firm called MedSec had indicated that St. Jude implants were vulnerable to two kinds of hacks: a “crash” attack that causes the devices to malfunction and a “battery drain” attack that could be harmful to device-dependent users.

In January 2017, the U.S. Food & Drug Administration (FDA) nnounced that it had confirmed cybersecurity vulnerabilities in the Merlin@home system that could allow a hacker to alter the transmitter. The altered transmitter could then be used to modify programming commands to the implanted device, which could result in rapid battery depletion and/or administration of inappropriate pacing or shocks. St. Jude has issued software updates to resolve some of the issues. The company is working with Homeland Security’s Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) to address the remaining vulnerabilities. Read More
