Abstract
The disclosure provides implementations for determining whether domain name server (DNS) beaconing is present within a communication session. Some implementations provide a method that includes multiple analyses directed to analyzing each of a time-to-live (TTL) run length distribution for a plurality of DNS records within the communication session and analyzing whether the communication is comprised of at least a threshold number of transmissions. As used in the analyses, the communication session may be comprised of transmissions between a first source device and a first DNS. When DNS beaconing is detected within the communication session, some implementations of the disclosure provide for generating an alert to an administrator or other user.
