    Abstract: Technologies are provided in example embodiments for analyzing an encrypted network flow. The technologies include monitoring the encrypted network flow between a first node and a second node, the network flow initiated from the first node; duplicating the encrypted network flow to form a copy of the encrypted network flow; decrypting the copy of the encrypted network flow using a shared secret, the shared secret associated with the first node and the second node; and scanning the network flow copy for targeted data.

    Abstract: In one embodiment, a processor comprises: a first register to store a first bound value for a stack to be stored in a memory; a second register to store a second bound value for the stack; a checker logic to determine, prior to an exit point at a conclusion of a function to be executed on the processor, whether a value of a stack pointer is within a range between the first bound value and the second bound value; and a logic to prevent a return to a caller of the function if the stack pointer value is not within the range. Other embodiments are described and claimed.

    Abstract: Systems and techniques for preventing malicious instruction execution are described herein. A first instance of an instruction for a graphics processing unit (GPU) may be received. The instruction may be placed in a target list. A notification that the instruction caused a problem with the GPU may be received. The instruction may be moved from the target list to a black list in response to the notification. A second instance of the instruction may be received. The second instance of the instruction may be prevented from executing on the GPU in response to the instruction being on the black list.

    Abstract: Technologies for hardware assisted native malware detection include a computing device. The computing device includes one or more processors with hook logic to monitor for execution of branch instructions of an application, compare the monitored branch instructions to filter criteria, and determine whether a monitored branch instruction satisfies the filter criteria. Additionally, the computing device includes a malware detector to provide the filter criteria to the hook logic, provide an address of a callback function to the hook logic to be executed in response to a determination that a monitored branch instruction satisfies the filter criteria, and analyze, in response to execution of the callback function, the monitored branch instruction to determine whether the monitored branch instruction is indicative of malware. Other embodiments are also described and claimed.

    Abstract: A malicious object detection system for use in managed runtime environments includes a check circuit to receive call information generated by an application, such as an Android application. A machine learning circuit coupled to the check circuit applies a machine learning model to assess the information and/or data included in the call and detect the presence of a malicious object, such as malware or a virus, in the application generating the call. The machine learning model may include a global machine learning model distributed across a number of devices, a local machine learning model based on use patterns of a particular device, or combinations thereof. A graphical user interface management circuit halts execution of applications containing malicious objects and generates a user perceptible output.

    Abstract: A processor includes an execution unit and a processing logic operatively coupled to the execution unit, the processing logic to: enter a first execution state and transition to a second execution state responsive to executing a control transfer instruction. Responsive to executing a target instruction of the control transfer instruction, the processing logic further transitions to the first execution state responsive to the target instruction being a control transfer termination instruction of a mode identical to a mode of the processing logic following the execution of the control transfer instruction; and raises an execution exception responsive to the target instruction being a control transfer termination instruction of a mode different than the mode of the processing logic following the execution of the control transfer instruction.
