PrivacyRights.org is a fantastic resource for cybersecurity researchers looking for information on data breaches. It contains an exhaustive list of laws per state on the disclosure of data breaches and what protections citizens have within those states. Additionally, the website contains a spreadsheet containing an absolute goldmine of data regarding past data breaches, including when the breach occurred, when it was publicly disclosed, in what city and to what company the breach occurred, how many records leaked, and a description of the incident. This is an invaluable font of knowledge for any cybersecurity researcher seeking to perform archival research on data breaches.
