The report is based on 5258 violations from 83 contributors around the world, one-third more than the violations analyzed last year.

In addition, the data also shows that 61% of vulnerabilities involve credential data; 95% of organizations that have suffered credential stuffing attacks have experienced between 637 and 3.3 billion malicious login attempts during the year.
