Overview

Domain Generation Algorithms (DGAs) are a DNS technique used by malicious actors to hide CnC servers behind newly generated, short-lived domains. They are generally used by malware to evade domain-based firewall controls. Malware that uses DGAs will constantly probe for short-lived registered domains that match the domain generated by the DGA to complete the CnC communication. This paper provides an explanation of Domain Generation Algorithms (DGAs) and looks at how they are used in DNS-based data exfiltration.
