We are happy to announce the release of the CISSM Cyber Events Dataset. This information brings together open-source information surrounding a range of publically acknowledged cyber events on private and public organizations. Events from 2014 through present have been coded to standardize information on threat actor, threat actor country, motive, target, end effects, industry, and country of impact. Source links to the news source are also provided.
