  • Patent number: 11308218
    Abstract: A method and system for remediating vulnerable code libraries, including open source libraries, in a software application. An application that uses code libraries and information regarding known library vulnerabilities are received, then it identifies one or more libraries in the application that are vulnerable based upon the information. For each of the one or more vulnerable libraries, a library version that minimizes risk is determined. The determined library version is incorporated into the application to form a test application, and an application test is performed on the test application. If an application test score on the test application is below a predetermined threshold, the determined library version is incorporated into a final application precursor. A final application can be determined from the final application precursor for each of the one or more vulnerable libraries.

  • Publication number: 20220078201
    Abstract: Various systems and methods for bus-off attack detection are described herein. An electronic device for bus-off attack detection and prevention includes bus-off prevention circuitry coupled to a protected node on a bus, the bus-off prevention circuitry to: detect a transmitted message from the protected node to the bus; detect a bit mismatch of the transmitted message on the bus; suspend further transmissions from the protected node while the bus is analyzed; determine whether the bit mismatch represents a bus fault or an active attack against the protected node; and signal the protected node indicating whether a fault has occurred.

  • Patent number: 11240659
    Abstract: Various embodiments are generally directed to techniques for providing improved privacy protection against vehicle tracking for connected vehicles of a vehicular network. For example, at least one road side unit may: identify a set of vehicles that require pseudonym changes and send an invitation for a pseudonym change event to each of the vehicles, determine at least a total number of the acceptances, determine whether the total number meets or exceeds a predetermined threshold number, send acknowledgement messages to the accepting vehicles if the threshold number is met, and form a vehicle group to coordinate the pseudonym change event during a privacy period. During the privacy period, the RSU and the vehicles may communicate with each other in a confidential and private manner via key-session-based unicast transmission, and coordinate transmission power and vehicle trajectory adjustments to maximize the benefits for safety and obfuscation for privacy.

  • Publication number: 20220014540
    Abstract: Systems, apparatuses and methods may provide for technology that detects one or more non-compliant nodes with respect to a timing schedule, detects one or more compliant nodes with respect to the timing schedule, and identifies a malicious node based on positions of the one or more non-compliant nodes and the one or more compliant nodes in a network topography.

  • Publication number: 20210120021
    Abstract: Systems and techniques for malicious request detection in automated resource dispatch are described herein. A request for a resource may be received from a user device. A location may be obtained for delivery of the resource. Sensor data may be retrieved for the location. The sensor data and user profile data may be evaluated to determine if the request is malicious. A disincentivizing message may be generated based on the determination that the request is malicious. In response to receipt of a response to the disincentivizing message, a resource may be dispatched to the location.
