Hacking a Subaru via text messages

Don Bailey and Mat Solnik from iSEC partners made a YouTube video showing the use of text messaging to hack into a Subaru Outback to unlock the door and start the engine. This was possible because systems like OnStar and Ford SYNC use text messaging to communicate with the car, via M2M (machine to machine) communication. The video isn't particularly exciting to watch, but NPR  (security-firm-hacks-a-car-with-a-text) and CBS (Theft via text: Cars vulnerable to hack attacks) went a bit deeper with their coverage, pointing out that it's not just cars using wireless communication chips, but other devices as well,  such as ATMs, medical devices and traffic lights. Obviously the manufacturers need to ensure that communications with these devices are secure.  But it's also another type of malicious activity over mobile messaging networks that the mobile operators are going to need to take into consideration.
