Spam Trends: December – February 2026
Results for spam activity for the period December 1 – January 31, 2026 are now available at Interisle's the Cybercrime Information Center. They include top-20 rankings of Top-level Domains, Domain Registrars, and Hosting Operators (by ASN) and aggregate records of all operators with phishing activity.
Overall, we saw a decline in spam figures in this reporting period, with unique domain names reported for hosting spammed content or spambots declining 36% versus the prior quarter and the number of subdomain reseller accounts reported for hosting spammed content by 30%. We cannot foresee changes in spamming tactics and how these affect resource consumption, but we’ll treat these significant reductions as a positive.
