mask.of.sanity writes "Researchers have demonstrated how controller area networks in cars can make vehicles appear to drive slower than their actual speed, manipulate brakes, wind back odometers and set off all kinds of alarms and lights from random fuzzing (video). The network weaknesses stem from a lack of authentication which they say is absent to improve performance. The researchers have also built a $25 open-source fuzzing tool to help others enter the field."
