Forbes

In 2014, Forbes became the victim of a data breach that exposed the personal information of 1057819 users. The leaked data included sensitive information such as email addresses, passwords, user website URLs, and usernames.

The breach was first discovered by security researcher Vinny Troia, who found a database containing the leaked information on a publicly accessible server. Troia then alerted Forbes, who quickly took action to secure the database and begin an investigation into the breach.
