Abstract: A system for distinguishing between a human voice generated command and an electronic speaker generated command is provided. An exemplary system comprises a microphone array for receiving an audio signal collection, preprocessing circuitry configured for converting the audio signal collection into processed recorded audio signals, energy balance metric determination circuitry configured for calculating a final energy balance metric based on the processed recorded audio signals, and energy balance metric evaluation circuitry for outputting a command originator signal based at least in part on the final energy balance metric.

Abstract: Disclosed are various embodiments for detecting Signaling System 7 (SS7) redirection attacks by measuring call audio round trip times between phones. Such redirection attacks force calls to travel longer physical distances than usual, thereby causing longer end-to-end delay. Accordingly, various embodiments implement a distance bounding-inspired protocol that allows for securely characterizing the round trip time between two call endpoints. As a result, telephone users can reliably detect SS7 redirection attacks and protect the information contained in their calls.

Abstract: Various examples are provided related to automated security analysis of baseband firmware. In one example, a system includes a wireless front end and processing circuitry communicatively coupled to the wireless front end and a target device. The processing circuitry can generate mutated packets based upon a device state of the target device; provide the mutated packets for transmission to the target device; receive feedback information from the target device in response to reception of the mutated packets; and identify a firmware flaw associated with the target device in response to the feedback information. In another example, a method includes generating mutated packets based upon a device state of a target device; transmitting the mutated packets to the target device; receiving feedback information from the target device in response to reception of the mutated packets; and identifying a firmware flaw associated with the target device using the feedback information.
