IEMI Threats for Information Security: Remote Command Injection on Modern Smartphones

Numerous papers dealing with the analysis of electromagnetic attacks against critical electronic devices have been made publicly available. In this paper, we exploit the principle of front-door coupling on smartphones headphone cables with specific electromagnetic waveforms. We present a smart use of intentional electromagnetic interference, resulting in finer impacts on an information system than a classical denial of service effect. As an outcome, we introduce a new silent remote voice command injection technique on modern smartphones.
