  • Patent number: 11385872
    Abstract: Operations include a compilation process and a runtime process. A compiler compiles code to generate virtual machine instructions. The compiler further generates information referencing respective parameter types of the parameters of a target virtual machine instruction. The compiler stores the information external to and in association with the target virtual machine instruction. The information may be included in another virtual machine instruction that precedes the target virtual machine instruction. A runtime environment processes the target virtual machine instruction based on the information stored external to and in association with the target virtual machine instruction. Parameter types referenced by the external information override parameter types that are (a) referenced by the target virtual machine instruction itself, (b) deduced by the runtime environment and/or (c) stored directly in association with the parameter values.

    Abstract: A kernel-based proactive engine can be configured to evaluate system call functions that are invoked when user-mode objects make system calls. As part of evaluating a system call function, the kernel-based proactive engine can generate a feature vector for the system call function. The kernel-based proactive engine can then analyze the feature vector using a multidimensional anomaly detection algorithm that has been trained using feature vectors of system call functions that are known to be safe. When the evaluation indicates that the feature vector is anomalous, the kernel-based proactive engine can block the system call.

  • Patent number: 11347617
    Abstract: A tracing controller may utilize a binary execution trace mechanism to trace execution of compiled application machine code. The tracing controller may initiate hardware tracing to gather control-flow hardware traces of a method executing on a processor configured to generate hardware tracing information.

Activities may include or be based on virtual machine states, virtual desktop states, business activities or processes performed by users, or the like. Then, the resource allocation manager determines that an activity is occurring on one of the virtual machines. In response, the resource allocation manager reallocates physical computing resources of the physical computing system that are assigned or available to the one virtual machine, based on the occurring activity and its corresponding importance.

  • Patent number: 11010495
    Abstract: Disclosed herein are embodiments of systems, methods, and products comprise a processor, which provides runtime enforcement of data flow integrity. The processor accesses the application binary file from the disk to execute an application and translates the application binary into intermediate representation. The processor applies the logic of data flow integrity controls to the intermediate representation. Specifically, the processor identifies the vulnerable code in the intermediate representation. The processor applies data flow integrity controls to the vulnerable code. The processor adds simple instrumentation that only changes the application's behavior when unauthorized data tampering occurs while preserving the application's normal behavior. When certain operations may cause unauthorized data tampering, the processor takes proper measures to stop the operations. The processor translates the intermediate representation back to a machine code and replaces the original binary with the machine code.

  • Patent number: 10990423
    Abstract: One embodiment illustrated herein includes a method that may be practiced in a computing environment with a guest architecture running a native architecture system. The method includes acts for handling function calls. The method includes receiving a call to a hybrid binary, wherein the call is in a format for the guest architecture. The hybrid binary includes a native function compiled into a native architecture binary code using guest architecture source code, an interoperability thunk to handle an incompatibility between the guest architecture and the native architecture, and native host remapping metadata that is usable by an emulator to redirect native host callable targets to the interoperability thunk. The method further includes invoking the interoperability thunk to allow the native function in the hybrid binary to be executed natively on the native architecture system.

  • Patent number: 10963561
    Abstract: Particular embodiments described herein provide for an electronic device that can be configured to help with the identification of a no-operation (NOP) sled attack identify. The system can be configured to receive an instruction, increment a value in a total instruction counter, increment a value in a branch instruction counter when the instruction is a branch instruction, increment a value in a memory instruction counter when the instruction is a memory instruction, create a ratio based on the value in the total instruction counter and the value in the branch instruction counter or the value in the memory instruction counter, and trigger an alert when the ratio satisfies a threshold. The ratio can indicate the presence of a NOP sled attack and the alert can be an interrupt that stops execution of the NOP sled.

  • Patent number: 10831884
    Abstract: Calling a function may include: determining whether a call is a direct or an indirect call. In response to determining that the call is an indirect call, a first address stored in a function pointer may be obtained, wherein the function pointer is stored at a first address in a stack frame of a calling function. Whether to execute a nested function call code sequence may be determined based on whether a tag bit in the first address stored in the function pointer is set. In response to determining that the tag bit in the first address is set, a second address stored at a nested function address location may be obtained, wherein the nested function address location is at the first address, and control may be transferred to a called function, wherein the called function is stored at the second address.

  • Patent number: 10817313
    Abstract: An initial workspace recommendation engine recommends a user interface component available for inclusion in an initial workspace of a newly installed application instance. In some cases, a classifier included in the engine classifies the available user interface component based on data describing multiple previously installed instances of the application. For example, the multiple instances are installed on multiple user devices, and are associated with user features describing the installed instances. In addition, the initial workspace recommendation engine receives a set of new user features associated with the newly installed application instance. The classifier classifies the available user interface component based on a similarity between the new user features and the user features describing the installed instances.

  • Patent number: 10803007
    Abstract: Provided are integrated circuit devices and methods for operating integrated circuit devices. In various examples, an integrated circuit device can include a memory for storing instructions a configuration register, and an instruction execution circuit. An instruction read from the memory can be a reconfigurable instruction. which includes a set of fields corresponding to a plurality of operations. Values in the fields can determine whether the operations are enabled or disabled. For example, a first value in a first field can enable a first operation. Whether the first operation is performed can further be determined by comparing a second value in a second field to a third value read from the configuration register. The value set in the configuration register thus can control whether the operation is performed.

  • Patent number: 10747510
    Abstract: Techniques to facilitate modifications to program execution in an application at runtime are disclosed herein. In at least one implementation, a copy of a code block associated with code is created. A flag associated with the copy of the code block is modified to mark the copy of the code block as having a native code version of the code. Metadata associated with the copy of the code block is modified to identify alternative code to run instead of the native code version of the code. A pointer associated with the code block is modified to point to a trampoline function. The trampoline function checks whether the code block is associated with a modification, and when the code block is associated with the modification, then the trampoline function calls the copy of the code block to invoke the alternative code by virtue of the flag and the metadata.
