Cyber security is a real issue. If you think that all we have to worry about is the script kiddie down the street with lots of time on your hand, you are mistaken. People like Barnaby Jack have made careers out of looking into the products that are dumped into the market, and exploring thier vulnerabilties, then going back the the manufacturers and showing them how to make thier products more secure. Security is a nusiance to most manufacturers ... they want to concentrate of features and benefits and time to market.
An interesting sidenote you can get by reading other articles on this ... Barnaby Jack was supposed to give this talk at this conference last year, but did not ... the manufacturers have had a full year to fix the software.
Yes, but having two ATMs and the software code to go along with them made his job easy to exploit whatever vulnerabilities that are found.
