It appears a new age of medical device security has dawned. The US agency for approval of medical devices and drugs has recently ordered a recall of all pacemaker devices manufactured by St Jude Medical.
Richard Staynings wrote on the 11th September 2017 "Last week the United States Food and Drug Administration took the unprecedented step of recalling a biomedical device following concerns over its lack of cybersecurity. The device in question — a St Jude Medical cardiac rhythm management product or pacemaker to the rest of us — had been successfully hacked in August 2016 at the behest of a financial trading company, Muddy Waters Capital, for stock market gain."
This could spell the beginning in a new era of cyber secure medical devices...
