There was a Defcon talk a few years ago (oh god it was 8 years ago) where someone found a way mess with Chryslers because they were all on the Sprint wireless network. Things like lock out the physical controls on the radio then max out the volume, or turn it into a GPS tracker, or disable the brakes! The cars had some service listening on port 6667, there was no way to stop them from accepting malicious connections so Sprint just blocked all traffic on that port on their network at the request of Chrysler. The speaker mentioned they were sorry if you were unable to use IRC any more on Sprint wireless.

Makes me wonder if there are any cyphers that are easy enough that human meat could implement it but hard enough that it would take some serious GPU time to crack?
