Malware Activity: Key Statistics Quarter over Quarter comparison: October 1, 2023 - December 31, 2023

Each reporting period, we analyze URLs, domain names, and IP addresses reported for serving up or distributing malware. We use these and other metadata — domain and IP address registration data, ICANN registry and registrar monthly reports, routing data, attack type, and other indicators — to report key statistics for each reporting period.

We compare number of domains reported for hosting malware in TLDs for two consecutive quarters in the table below.

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.
