Given how much money there is up for grabs, I imagine the next such implant won’t be anything as easily detectable as a Raspberry Pi. For a modest outlay that would fit within existing malware budgets, it would be possible to build a device that fits inside an otherwise conventional-looking Ethernet or USB cable and has enough power to relay traffic across the network. (I wouldn’t be surprised if you could buy those pre-built.)
