  • Automated security analysis of baseband firmware
    Patent number: 11663338
    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.

  • Protocol model learning and guided firmware analysis
    Patent number: 11640464
    Abstract: The present disclosure describes a firmware analysis system and method that can generate a collection of protocol constraints from known firmware and apply the collection of protocol constraints towards an unknown firm to recognize protocol relevant fields and detect functionality within the unknown firmware.
