Malware Activity: Top-level Domains Quarter over Quarter Comparison: April 1,2026 - June 30,2026

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 two consecutive quarters.

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.
