T1637.001 Domain Generation Algorithms

Adversaries may use Domain Generation Algorithms (DGAs) to procedurally generate domain names for uses such as command and control communication or malicious application distribution.2

DGAs increase the difficulty for defenders to block, track, or take over the command and control channel, as there could potentially be thousands of domains that malware can check for instructions.
