  • Classification of executable files using a digest of a call graph pattern
    Patent number: 11157620
    Abstract: A cybersecurity server receives an executable file to be classified. A call graph of the executable file is generated. Functions of the executable file are represented as vertices in the call graph, and a vertex value is generated for each vertex. The vertex values are arranged in traversal order of the call graph to generate a call graph pattern. A digest of the call graph pattern is calculated and compared to one or more malicious digests.
    Type: Grant
    Filed: January 21, 2020
    Date of Patent: October 26, 2021

  • Detection of advanced persistent threat attack on a private computer network
    Patent number: 10320814
    Abstract: A system for detecting an advanced persistent threat (APT) attack on a private computer network includes hosts computers that receive network traffic and process the network traffic to identify an access event that indicates access to a critical asset of an organization that owns or maintains the private computer network. The critical asset may be a computer that stores confidential data of the organization. Access events may be stored in an event log as event data. Access events indicated in the event log may be correlated using a set of alert rules to identify an APT attack.
