ICANN Publishes Reputation Block List Analysis for IDNs Q3 2023–Q4 2025
The Internet Corporation for Assigned Names and Numbers (ICANN) has published the Analysis of Internationalized Domain Names in Reputation Block List Data for the period of October 2023-September 2025. Reputation Block Lists (RBLs) include malicious domain usage data from third-party reputation providers. Security systems throughout the Internet use RBLs to block those domain names and prevent malicious activity.
This report includes an analysis of Internationalized Domain Name (IDN) data in RBLs associated with three categories of Domain Name System Abuse: botnets, malware, and phishing, as tracked by the ICANN Domain Metrica project.
Key findings include:
- Ratio of percentage of reported American Standard Code for Information Interchange (ASCII) domain names to percentage of reported IDNs is 5.3 to 1 (0.47 percent to 0.09 percent).
- Both reported ASCII domain names and reported IDNs have similar distribution of the security threats across threat types. Phishing is the most reported security threat type (98.98 percent of reported IDNs).
- The majority of the reported IDNs consist of Latin script (0.26 percent of total Latin IDNs) and Chinese (Han) script (0.04 percent of total Han IDNs).
Please consult the full report for more details. The previous reports can be found on the IDN Resource Page.
