Breaches & incidents

The victims' side of the threat pictureWho is being attacked

Data breaches and cyber incidents made public — reported to regulators, disclosed by the companies themselves, or catalogued after a leak. Who was hit, when, how, and how many people or accounts were affected.

Incidents disclosed: 613; last 12 months, every source
People in US health breaches: 70.4M; 474 breaches reported to HHS
Material incidents, US listed firms: 22; SEC 8-K Item 1.05, 12 months
Accounts in new breach records: 521.9M; 125 breaches added to HIBP

Coverage. Mostly the United States: the cleanest public records of named victims come from US regulators. Ransomware victims worldwide, India included, are on the ransomware victims page. Every count is a lower bound — only disclosed incidents appear.
