"I managed to borrow a couple of USB ethernet adapters, set up a
transparent bridge (brctl addbr br0; brctl addif br0 enp0s20f0u1;
brctl addif br0 enp0s20f0u2; ifconfig br0 up) and then stuck my
laptop between the tablet and the wall. tcpdump -i br0 showed
traffic, and wireshark revealed that it was Modbus over TCP. Modbus
is a pretty trivial protocol, and notably has no authentication
whatsoever. tcpdump showed that traffic was being sent to
172.16.207.14, and pymodbus let me start controlling my lights,
turning the TV on and off and even making my curtains open and
close. What fun! "
