  • Publication number: 20230377318
    Abstract: The present disclosure belongs to the technical field of image processing, and provides a multi-modal image classification system and method using an attention-based multi-interaction network. The present disclosure utilizes a U-net network structure to fuse low-level visual features and high-level semantic features. An attention network is introduced to solve the problem of weak feature discrimination, and high attention is given to discriminative features, so that the attention network plays an important role in the final classification process. A sufficient multi-modal interaction mechanism is introduced, so that more effective correlation information and discriminative information are obtained among a plurality of modalities, and sufficient interaction among the plurality of modalities is completed, thereby solving the problems of weak feature discrimination and insufficient interaction among modalities in a multi-modal image classification task.

  • Patent number: 10162966
    Abstract: A malware detection system for evaluating sample programs for malware incorporates an evasion code detector. The evasion code detector includes semantic patterns for identifying conditional statements and other features employed by evasion code. The system inserts breakpoints at conditional statements, compares expected and actual evaluated values of conditional variables of the conditional statements, and changes the execution path of the sample program based on the comparison. Changing the execution path of the sample program to an expected execution path counteracts the evasion code, allowing for the true nature of the sample program to be revealed during runtime.

  • Patent number: 9917855
    Abstract: A sandbox system includes a mixed analysis engine that allows for dynamic and static analysis of a sample process for malware. The sample process is executed in a virtual machine and interrupted to allow the mixed analysis engine to identify functions that are called by malware to perform a malicious behavior. The functions are correlated to identify a behavior node that is indicative of the malicious behavior, and behavior nodes are correlated to identify a behavior net. The behavior net is scored to determine if the sample process is malware.

  • Patent number: 9305514
    Abstract: Tablet computers send relevant geographic and identification data to an application server (one of the tablets, or a local or remote server) which groups them to form a video wall. Once placed next to one another in substantially the same plane, the tablets snap photographs at more or less the same time and these images are transmitted to the application server. The server determines the relative positions of the tablets and then streams a portion of a video or digital image to each of the tablets in order that all tablets display the video or image in an integrated fashion. The tablets may operate independently or may rely upon the remote application server. Relative positions are determined by analyzing features and determining an up-down or left-right relationship between pairs of images, sorting images into vertical and horizontal rows, and placing the images into a grid.

  • Patent number: 9239922
    Abstract: An application document known to include malware (such as a document exploit) is opened and executed by its corresponding software application. Behaviors of this document (such as registry, file system, network and process) are monitored and recorded using internal software drivers and hook modules. A behavior report is generated and a baseline pattern is created including a number of regular expressions. A suspicious document of the same type as the monitored document is opened and executed by the same corresponding software application. Behaviors are monitored in the same way and a behavior report is generated. This behavior report is compared to the baseline pattern and a determination is made as to whether a document exploit is present. Known benign documents may also be opened, monitored and their behavior recorded, resulting in creation of a known benign pattern for the corresponding software application.

  • Patent number: 9117079
    Abstract: A single virtual machine is implemented upon a computer and an operating system executes within this virtual machine. A sample file suspected of being malware is received and any number of versions of the software application corresponding to the sample file are installed. Each version of the software application is executed within the operating system, each version opening the sample file. Behavior of each version and of the sample file is collected while each version is executing. A score indicating malicious behavior for each version with respect to the sample file is determined and reported. The versions may execute serially in the happening system, each version terminating before the next version begins executing. Or, all versions may execute concurrently within the operating system. Files and registries are hidden to facilitate installation. System information is changed to facilitate execution.

  • Patent number: 8484732
    Abstract: Computers are protected against virtual machine exploits. A computer includes an exploit monitor for a virtual machine running in the computer. Loading of a virtual machine program in the virtual machine triggers the exploit monitor to modify the virtual machine program after the virtual machine program is loaded in the virtual machine but before the virtual machine program is executed in the virtual machine. The modification includes adding monitoring code, such as one or more checkpoints, in the virtual machine program. When the monitoring code is reached during execution of the virtual machine program in the virtual machine, the virtual machine program is evaluated to determine whether or not the virtual machine program is a virtual machine exploit.
