Abstract: Various embodiments include systems and methods of determining whether media access control (MAC) address spoofing is present in a network by a wireless communication device. A processor of the wireless communication device may determine an anticipated coherence interval based on a beacon frame received from an access point. The processor may schedule an active scan request and may determine whether a response frame corresponding to the scheduled active request is received within the anticipated coherence interval. The processor may calculate a first correlation coefficient in response to the response frame being received within the anticipated coherence interval and may determine that MAC address spoofing is not present in the network when the first correlation coefficient is greater than a first predetermined threshold.

Abstract: Systems, methods, and devices of the various aspects enable identification of anomalous application behavior. A computing device processor may detect network communication activity of an application on the computing device. The processor may identify one or more device states of the computing device, and one or more categories of the application. The processor may determine whether the application is behaving anomalously based on a correlation of the detected network communication activity of the application, the identified one or more device states of the computing device, and the identified one or more categories of the application.

Abstract: Various methods, apparatuses and articles of manufacture are provided which may be used in determining an altitude of a mobile device. For example, an electronic device may select a subset of reporting mobile devices located within a particular environment, estimate a reference parameter that is indicative, at least in part, of a reference altitude within the particular region, e.g., based, at least in part, on one or more altitude measurements for one or more of the reporting mobile devices, and initiate transmission of the reference parameter to at least a target mobile device. In another example, a mobile device may obtain such a reference parameter, and estimate its altitude based, at least in part, on the reference parameter.

Abstract: Methods, and computing devices implementing the methods, that enable client computing devises to work in conjunction with a server device to identify and temporarily defend against non-benign applications (e.g., malware, etc.) and other threats before a more permanent solution or defense (e.g., a patch or software upgrade) becomes available and installed on the client computing device. The server device may be configured to receive reports from the client computing devices, receive threat feeds from a third-party server (e.g., threat intelligence servers, etc.), and use information included in the received threat feed and information included in the received reports to analyze, in the server computing device, a software application that is operating on a client device in multiple passes. The server may generate one or more threat scores and send the one or more threat scores to the client computing device for use in devising a customized security response.

Abstract: Methods and apparatus for enhanced overlay state maintenance in a peer-to-peer overlay network. A first method includes inferring that a first node is leaving the overlay network, and transmitting a decrement message to decrement a size counter value. A second method includes identifying a set of nodes associated with a first node of an overlay network, obtaining a segment length associated with each node of the set of nodes, and determining a size of the overlay network by dividing the total number of nodes in the set of nodes by the sum of the segment lengths. A third method includes identifying a set of nodes associated with a first node of an overlay network, obtaining a size estimate associated with the first node and with each node of the set of nodes, and determining a size of the overlay network by averaging the size estimates.

Abstract: A network and its devices may be protected from non-benign behavior, malware, and cyber attacks caused by downloading software by configuring a server computing device to work in conjunction with the devices in the network. The server computing device may be configured to receive a software application from an application download service, establish a secure communication link to a client computing device in the network, receive exercise information from the client computing device via the secure communication link, use the received exercise information to exercise the received software application in a client computing device emulator to identify one or more behaviors, and determine whether the identified behaviors are benign. The server computing device may send the software application to the client computing device in response to determining that the identified behaviors are benign, and quarantine the software application in response to determining that the identified behaviors are not benign.

Abstract: Various embodiments include methods, and computing devices implementing the methods, for analyzing sensor information to identify an abnormal vehicle behavior. A computing device may monitor sensors (e.g., a closely-integrated vehicle sensor, a loosely-integrated vehicle sensor, a non-vehicle sensor, etc.) in the vehicle to collect the sensor information, analyze the collected sensor information to generate an analysis result, and use the generated analysis result to determine whether a behavior of the vehicle is abnormal. The computing device may also generate a communication message in response to determining that the behavior of the vehicle is abnormal, and send the generated communication message to an external entity.

Abstract: Various embodiments include methods, and computing devices implementing the methods, for authenticating vehicle information by polling selected sensors. A server computing device receiving vehicle information from a reporting vehicle may compare the received vehicle information to contextual information to generate a comparison result, and determine whether the received vehicle information should be evaluated with greater scrutiny based on the comparison result. The server computing device may select sensors for polling based on the received vehicle information (and in response to determining that the received vehicle information should be evaluated with greater scrutiny), and poll the selected sensors to received sensor information. The server computing device may use the received sensor information to corroborate the received vehicle information, and perform a responsive action based on the result of the corroboration.
