Abstract
A method includes operations of accessing domain name server (DNS) Txt records, each including text data and each representing one or more transmissions of data between a source device and a destination device, performing a tokenizing operation on the text data of the one or more DNS Txt records to generate a set of tokenized DNS Txt records and applying a trained machine learning model to the one or more DNS Txt records resulting in classification of at least a first DNS Txt record of the one or more DNS Txt records with respect to a likelihood of being an indicator of DNS beaconing. Additional operations include based on the classification, determining the DNS Txt records are indicative of DNS beaconing between the source device and the destination device, and generating an alert that the source device is engaged in DNS beaconing.
