  • DETECTING PHISHING PDFS WITH AN IMAGE-BASED DEEP LEARNING APPROACH
    Publication number: 20230344867
    Abstract: The detection of phishing Portable Document Format (PDF) files using an image-based deep learning approach is disclosed. A PDF document that includes a Universal Resource Locator is received. A likelihood that the received PDF document represents a phishing threat is determined, at least in part, by using an image based model. A verdict for the PDF document is provided as output based at least in part on the determined likelihood.

  • Simulating user interactions for malware analysis
    Patent number: 11706251
    Abstract: Simulating user interactions during dynamic analysis of a sample is disclosed. A sample is received for analysis. Prior to execution of the sample, a baseline screenshot of a system folder is generated by accessing frame buffer data stored on a graphics card. The sample is caused to execute, at least in part using one or more hypervisor instructions to move a pointing device to an icon associated with the sample. A current screenshot of the system folder is generated by accessing current frame buffer data stored on the graphics card.

  • EARLY EXIT DYNAMIC ANALYSIS OF A VIRTUAL MACHINE
    Publication number: 20230004639
    Abstract: Techniques for early exit dynamic analysis of a virtual machine are disclosed. In some embodiments, a system/process/computer program product for early exit dynamic analysis of a virtual machine includes initiating a dynamic analysis of a malware sample by executing the malware sample in a virtual computing environment; monitoring activities of the malware sample during execution of the malware sample in the virtual computing environment; and determining when to exit the dynamic analysis before a predetermined period of time.

  • Simulating user interactions for malware analysis
    Patent number: 11196765
    Abstract: Simulating user interactions during dynamic analysis of a sample is disclosed. A sample is received for analysis. Prior to execution of the sample, a baseline screenshot of a desktop is generated by accessing frame buffer data stored on a graphics card. The sample is caused to execute, at least in part using one or more hypervisor instructions to move a pointing device to an icon associated with the sample. A current screenshot of the desktop is generated by accessing current frame buffer data stored on the graphics card.
