> an attacker passively eavesdropping a GSM communication between a target and a base station can decrypt any 2-hour call with probability 0.43, in 14 min

The authors give the above example in the abstract. It does not look like the typical use case for embedded systems. I would think embedded systems send and receive small amounts of non-critical data over GSM, hopefully encrypted, as the parent pointed out. But I may be wrong here - is there a real use case for attacking embedded systems using this method?

yeah, any IoT device that has been built with the assumption of GSM being not eavesdroppable. Cars and alarm systems come to my mind here.
