A $4,200 Japanese toilet from Satis has a lot of features, including a hard-coded Bluetooth PIN that could allow remote access to a toilet hacker. Conceivably, a toilet hijacker could make the device appear as if the owner’s home was infested with poltergeists, closing and opening the lid, spraying the room with the bidet spout, and playing music from the toilet’s SD card while the bowl light switches on and off.
