In September 2019, we started a dataset of Critical Infrastructures Ransomware Attacks (CIRAs). These are based on publicly disclosed incidents in the media or security reports. This dataset (version 12.16) now has 2,291 records assembled from publicly disclosed incidents between November 2013 and December 31, 2025, and has been mapped to the MITRE ATT&CK Framework. To date, we have fulfilled 1,806 requests. Some publicly known uses of the dataset can be found in research papers and reports.
If you use the dataset, in whole or in part, for any analysis, publication, presentation, or any other dissemination (including social media), you agree to cite this dataset in your reference list as:
