"It would require technical expertise, sophisticated equipment and proximity to the pump." A spokesman for the company says it's working to eliminate the vulnerability; it has laid out a series of steps patients can take to reduce the risk, such as turning off the pump's wireless connection to a blood-sugar meter, or setting a limit on the amount of insulin that can be delivered. The announcement is yet another stark reminder of known security issues that exist with medical devices, widely used by both providers and patients. Indeed, this is not the first time concerns have surfaced about the ease of hacking medical devices. In mid-2015, the Food and Drug Administration took the unprecedented step of alerting users about cybersecurity vulnerabilities of the Hospira Symbiq Infusion System. The agency strongly encouraged healthcare facilities to discontinue use of the pumps. And the FDA is not the only federal agency shining a spotlight on the vulnerabilities of medical devices.
