So if I understand this correctly, the "hack" works like this: 1. Install malware onto both the Target and the Receiver computers 2. Use existing circuitry inside the computer to create a software radio 3. Use the software radio created in Step 2 to transmit data between Target and Receiver This demonstration glossed over the difficulty of Step 1, something we saw in play with the Stuxnet virus. This demonstration failed at Step 2, when a suitable circuit could not be located. Part of that is likely due to the large size of AM radio waves, and thus the large antennas required to generate them effectively. If microwave transmission were used, a suitable circuit would be much easier to find. There are many questions about the viability of this "hack", not the least of which are the ability to get enough power to the antenna to transmit data through several layers of metal insulation and electromagnetic noise. Who knows - maybe the future of WIFI won't be discrete hardware antennas, but software that can generate a software antenna from any circuit in the device on-demand. This might be useful for transmitting data short ranges, like just across a CPU core.
