Disclaimer:

Our database is compiled from publicly available information that has been hand-picked and retrieved from both the Clear Web and the Dark Web.

For every attack we collect and classify, we calculate an Estimated Severity Index (ESIX©) on a scale of one to ten, corresponding to four impact categories, from low to critical.

ESIX© is based on a set of proprietary algorithms and AI predictive models developed by Hackmanac that consistently evaluate multiple variables, including social, economic (direct and indirect), technical, and reputational impact. It is a metric designed to inform strategic board-level decisions and support the work of cybersecurity, GRC, threat intelligence, business continuity, insurance, and enterprise risk management teams.
