Malware Activity: Domain Registrars
Quarter over Quarter Comparison January 1,2024 - March 31,2024

For purposes of observing change over time, it is useful to compare measurements and metrics over successive reporting periods. Such comparisons illustrate whether malware activities are increasing or decreasing, and where such changes are occurring. Such comparisons can identify registrars where malware attackers flock to purchase and manage malware domains. Investigators or policy makers may focus on these for deeper analyses.

Complete lists of Top-level Domains, gTLD registrars and hosting networks (ASNs) where malware was reported for the quarter can be downloaded in CSV format from the Records page.

In the table below, we compare the number of domains reported for hosting malware under management at domain registrars for two consecutive quarters.
