Abstract: The present embodiments relate to identifying and mitigating memory bit flips in a cloud infrastructure service. The cloud infrastructure service can provide a monitoring system to monitor low level memory space to detect bit flips by the DRAM instances in the cloud infrastructure service. The bit flips detected in various DRAM computing instances can be processed to verify that the bit flips are sustained (e.g., and possibly relating to a Rowhammer attack) rather than transitory bit flips occurring in DRAM computing devices. Responsive to validating a set of bit flips at one or more computing instances, workloads associated with the affected computing instances can be migrated to other computing instances in the cloud infrastructure service.

Abstract: Aspects of the disclosure include a dynamic cloud workload reallocation based on an active ransomware attack. An example method includes receiving a first message that a computing instance is potentially infected by ransomware. The method further includes receiving a security state-based metric related to the computing instance based at least in part on the first message. The method further includes comparing the security state-based metric to a threshold metric. The method further incudes determining a likelihood of a ransomware attack based at least in part on the comparison. The method further includes transmitting second message to a job scheduler to reschedule workloads directed toward the computing instance based at least in part on the determination.

Abstract: The present embodiments relate to identifying a ransomware attack. One embodiment relates to a method comprising configuring an operating system to collect metrics related to a hardware component. A message can be received from a user space library to validate an instruction detected in a cache, the instruction being associated with the hardware component. A metric can be compared to a threshold metric. The metric can be associated with the hardware component. A likelihood of a ransomware attack can be determined based at least in part on the comparison. A message can be transmitted to the user space library comprising the determination of the likelihood of the ransomware.

Abstract: An identity management server can be used to provide identity-based authentication and access control mechanism for devices trying to connect to a network or other devices on the network. The identity management server may authenticate a user associated with a device based on the past behavior information of the user received from another device associated with the user. The identity management server may generate a trust score based on multiple attributes associated with the user and the device, and authenticate the user if the trust score is within an acceptable limit. The identity management server may also generate access permissions for the device, which can be used by a network device to grant or deny access to the network.

Abstract: An example method for detecting undervolting of a core of a multi-core processing unit includes reading a value of an entry counter and a value of an exit counter. The value of the entry counter indicates that a core of the multi-core processing unit has begun executing a code section, and the value of the exit counter indicates that the core has completed executing the code section. The method also includes determining that the core was undervolted when: (i) the value of the entry counter is not the same as the value of the exit counter, and (ii) a core power resource does not satisfy a power resource threshold for the core.

Abstract: Systems and methods for booting up a mobile device involve segmenting a boot sequence of the mobile device into a plurality of boot sequence segments and determining a first boot sequence segment from the plurality of boot sequence segments, battery power consumed by the first boot sequence segment exceeds a predetermined battery power threshold. In addition, systems and methods further include selecting a target boot mode from a plurality of boot modes. The target boot mode is configured to be executed when the first boot sequence segment of the boot sequence is to be executed, and each of the plurality of boot modes corresponds to at least some but not all resources of the mobile device. Furthermore, systems and methods involve executing the first boot sequence segment based on the target boot mode and executing at least one of the plurality of boot sequence segments other than the first boot sequence segment based on a normal mode. The normal mode corresponds to all resources of the mobile device.

Abstract: A user device having a plurality of modules for implementing one or more use cases, maps one or more sensor outputs to a use case based on sensor outputs obtained during a hang/reset state of the user device during the use case. Each of the one or more sensor outputs is associated with one of the plurality of modules. The user device also maps one or more actions to each sensor output mapped to the use case. The one or more actions affect a change in an operating parameter of the module associated with the sensor output during a hang/rest state of the user device during the use case. The one or more actions also affect a corresponding change in the sensor output mapped to the use case.

Abstract: A framework and associated systems and methods for testing mobile communication devices are disclosed. An exemplary method includes receiving user-action data from each of a plurality of user-action-capture devices. The user-action data received from the user-action-capture devices includes data that characterizes a plurality of user actions that were performed on the user-action-capture devices. The user-action data is consolidated into generic representations of the user actions to create a superset of generally-applicable-user-action data, and each generic representation of a user action in the superset represents two or more similar user actions. The generally-applicable-user-action data is then used to test mobile communication devices that are different than the user-action-capture devices.

Abstract: Methods and mobile devices for performing operations responsive to user actions are disclosed. The method includes prompting a user of a mobile device to make a particular action that is detectable by the mobile device, and prompting the user to select a particular operation that the user desires to have effectuated when the particular action is subsequently carried out. In addition, an indicator of the particular action is stored on the mobile device in connection with an indicator of the particular operation to associate the particular action with the particular operation. And after registration, when the particular action is sensed with the mobile device, the particular operation is effectuated.

Abstract: A very intuitive and simple set of touch-screen input steps along with the processing of those input steps allows a user to appear to gather shareable files with his fingers on one touch-screen apparatus, lift the files from the touch-screen and drop the shareable files on a touch screen of a second, co-located touch-screen apparatus. The touch-screen apparatus initiating the transfer of files is preset with sharing parameters to manage the transfer of files to a local or remote server. One or more touch-screen apparatus accepting the transfer of files is preset with acceptance parameters to manage the transfer of files from the server to the accepting touch-screen apparatus. Once the files are at the server, multiple touch-screen apparatus may be used to request shareable files from the server.

The first portion may invoke an application program interface (API 1402) to instruct the second portion to replace a current set of signal acquisition parameters with an initial set of signal acquisition parameters.

Abstract: Methods and systems for applying power to a mobile device responsive to user actions are disclosed. An exemplary method includes detecting, while a mobile device is powered down, actions made by a user in connection with the user handling the mobile device without pressing a power button of the mobile device. A prediction is then made that the user is about to power up the mobile device based upon particular actions made by the user. And before the user presses the power button, power is applied to processing and network communication components of the mobile device so that if the user presses the power button, the processing and network communication components are already powered; thus reducing an amount of time it takes for the mobile device to access a network with the mobile device.
