Type Name Severity Module Data source / event ATT&CK
Analytics Failed DNS The endpoint is performing DNS lookups that are failing at an excessively high rate when compared to its peer group. This alert might be symptomatic of malware that is trying to connect to its command and control (C2) servers. The attacker's C2 server runs on one or more domains that can eventually be identified and blacklisted. To avoid this, malware will sometimes use Domain Generation Algorithms (DGA) that produce many 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.

Analytics Random-Looking Domain Names The endpoint performed DNS lookups to an excessively large number of apparently random root domain names. This alert might be symptomatic of malware that is trying to connect to its command and control (C2) servers. The attacker's C2 server runs on one or more domains that can eventually be identified and blacklisted. 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.
