Malware Activity: Top-level Domains
Quarter over Quarter Comparison:
October 1, 2021 - December 31, 2021
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 TLDs that are persistently abused or exploited to host malware. Investigators or policy makers may focus on these for deeper analyses.
In the table below, we compare number of domains reported for hosting malware in TLDs for the two consecutive quarters.
