Private data exfiltration from cyber-physical systems using channel state information

Abstract:

Data exfiltration methods aim to extract data without authorization from a network or device without detection. In this paper, we present a novel data exfiltration method using Channel State Information (CSI) from ambient WiFi signals. Modulation is performed by modifying the environment by moving a physically actuated machine resulting in a change to the channel response that is measurable by a distant receiver capable of collecting CSI samples. An attacker can use this to exfiltrate data wh...
