I wasn’t really paying attention the first time I read the report, but I later noticed that Verizon mentions that the RAM scraper was found on a P.O.S.  (point of sale – the system a cashier will use to check out a customer in a store) system. A P.O.S. system would seem to be a system which could be very well defined in terms of what should be running on it, and would seem to be an ideal candidate for whitelisting software. Getting rid of the AV on P.O.S. systems and replacing them with whitelisting software which only allows specific applications to run would seem to be an ideal way to greatly increase the security of these systems, and make them future-proof against whatever the next generation of malware is.
