The name "PowerHammer" is also a bit of a mismatch. It's basically a covert channel via power consumption, which has been known. The transmission mechanism (write) is to idle the CPU for specific intervals of time in order to transmit bits. Impressive engineering, impressive bitrate, but not so novel an idea, overall.
