To avoid this, malware will sometimes use Domain Generation Algorithms (DGA) that produce many unique, random-looking domain names every day. Because only a few of these domains are ever registered, the installed malware must blindly try to access each generated domain name in an effort to locate an active one, which may also trigger the Failed DNS alert.
