Watt, Me Worry? Analyzing AC Power to Find Malware
Side channels have been widely used to spy on users. What if we spied on malware instead? It turns out that execution on the CPU creates observable patterns on the AC power line. We use this side channel to detect malware and other anomalies from a single measurement point at the wall. We’ll describe the research that drives our work and explain how to use power side channels for good.
