  • DETECTING SHADOWED DOMAINS
    Publication number: 20240039890
    Abstract: A method and system for detecting shadowed domains is provided. New hostnames are collected for a predetermined period of time. Candidate shadowed domains are selected from the new hostnames. Classification of the candidate shadowed domains is performed based on a plurality of features relating to the candidate shadowed domains to output a set of identified shadowed domains. An action is performed based on the set of identified shadowed domains.

  • AUTOMATED EXTRACTION AND CLASSIFICATION OF MALICIOUS INDICATORS
    Publication number: 20240031383
    Abstract: Techniques for generating actionable indicators of compromise (IOCs) are disclosed. A set of potential sources for IOCs are received. One or more candidate IOCs are extracted from at least one source included in the set of potential sources. An actionable IOC is automatically identified from the one or more candidate IOCs. The actionable IOC is provided to a security enforcement service.

  • SYSTEM AND METHOD FOR DETECTING DICTIONARY-BASED DGA TRAFFIC
    Publication number: 20230336528
    Abstract: A system and method for detecting dictionary-based DGA traffic is provided. A domain name system (DNS) stream is received. The DNS stream is classified using a per domain dictionary domain generation algorithm (DGA) classifier to generate candidate dictionary DGA domains with cluster information. The candidate dictionary DGA domains are filtered to generate a set of dictionary DGA domains. An action is performed based on a match with a monitored domain name of a monitored DNS request and a dictionary DGA domain of the set of dictionary DGA domains.
