How does domain generation algorithm work?

Domain generation algorithms (DGA) are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers. For example, an infected computer could create thousands of domain names such as: www.

Why are DGAs useful for cyber criminals?

DGAs are code that programmatically produce a list of domains used by malware clients to communicate with a sequence of command and control (C&C) sites. These domains are used as rendezvous points for malware and hacker controlled servers to communicate stealthily on a backhaul network.
