The hosts file on endpoints is used to control manual IP address to hostname resolutions. The hosts file is the first
point of lookup for DNS hostname resolution so if adversaries can modify the endpoint hosts file, they can route traffic
to malicious infrastructure. This rule detects modifications to the hosts file on Microsoft Windows, Linux (Ubuntu or
RHEL) and macOS systems.
