So far, the article only mentions the Minimed 508 which is confirmed by this letter on Medtronics’s website.
The MiniMed™ 508 insulin pump and the MiniMed™ Paradigm™ series insulin pumps are designed to communicate using a wireless radio frequency (RF) with other devices such as a blood glucose meters, glucose sensor transmitters, and CareLink™ USB devices.
Security researchers have identified potential cybersecurity vulnerabilities related to these insulin pumps. An unauthorized person with special technical skills and equipment could potentially connect wirelessly to a nearby insulin pump to change settings and control insulin delivery. This could lead to hypoglycemia (if additional insulin is delivered) or hyperglycemia and diabetic ketoacidosis (if not enough insulin is delivered).
