Using the data collected over the past year and using Kibana these two ES|QL query to summarize the data, this shows the list of the most uploaded threat to two DShield sensors (local and cloud) over the past year. I have sorted the activity by months that shows the evolution of files uploaded to the sensors each month. The activity peaked during the winter months (Dec 2025 - Feb 2026) and started decreasing in March 2026 for each sensor.
