Malware Activity:Hosting Networks (ASNs) Quarter over Quarter Comparison
July 1,2023 - September 30,2023

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 identify hosting networks where malware is being hosted and whether or not such activity is persistent or atypical. Investigators or policy makers may focus on these hosting networks 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 numbers of malware records reported for hosting malware in hosting networks (ASNs) for two consecutive quarters.
