Newly Active Hostnames (NAH)
Domains are sometimes warmed up — often showing the appearance of legit activity — to avoid detection before suddenly turning malicious, making this data a very valuable subset of domains to analyze when looking for malicious activity.
A hostname is considered newly active when its activity (queries originating from different IPs) transitions from dormant or nearly dormant to active or very active.
