  • Detecting malicious domains and client addresses in DNS traffic
    Patent number: 10382478
    Abstract: In one embodiment, a device in a network constructs a graph based on Domain Name System (DNS) traffic in which vertices of the graph correspond to client addresses from the DNS traffic and domains from DNS traffic. The device uses stacked autoencoders to determine priors for the domains and client addresses. The device assigns the determined priors to the corresponding vertices of the graph. The device uses belief propagation on the graph to determine a malware inference from the graph. The device causes performance of a mitigation action when the malware inference from the graph indicates the presence of malware.
