Bugging corporate appliances is easy as well if done by design. A WiFi repeater box plugged in the conference room wall could have a miniscule MEMS microphone and audio preamp wired to a ADC port on the main microcontroller (assuming it's too small to have an audio input), so that it can listen and relay elsewhere when instructed to. And let's not forget about networked printers or even the coffee machine if connected. At an old company I worked with, many decisions of vital importance were taken while drinking coffee on the armchairs around the machine.
