We all use Bluetooth and other wireless systems. Those systems give us freedom to operate. When we listen to music. Or do something. Like that. Wireless systems are free from wires, but sometimes we should ask, what if somebody hacks those systems? The effective distance. Of Bluetooth communication. It is about 20-100 meters. Bluetooth 5 has an effective distance that can be longer than 200 meters. And if somebody could hack the Bluetooth key that the system uses for making connections, that would allow that actor to transmit information into those Bluetooth devices. If somebody wants to transmit so-called subliminal acoustic signals to the receiver, that system doesn’t need two-way communication. The high-power electronic warfare system can make that thing possible. Hacking those systems is always a big risk. But when we think about things like Brain-implanted microchips. And Brain-Computer Interfaces, those systems allow operators to hack. The person’s mind. The system that conn...
