  • METHODS TO DETECT DNS HIJACKING
    Publication number: 20260039681
    Abstract: The present application discloses a method, system, and computer system for detecting DNS hijacking records. The method includes (i) obtaining passive DNS (pDNS) data pertaining to a set of resource records, (ii) extracting a first set of features based at least in part on the pDNS data for a selected resource record, wherein the selected resource record is selected from the set of resource records, (iii) using a classifier to determine whether a candidate record corresponding to the selected resource record is a result of a DNS hijacking based at least in part on the first set of features, and (iv) performing an active measure in response to determining that the candidate record is the result of the DNS hijacking.
