Mate1.com

In February 2016, a massive data breach occurred at Mate1.com, a popular online dating site. The breach exposed the personal information of over 27 million users, making it one of the largest data leaks in history.

The compromised data included sensitive information such as email addresses, passwords, phone numbers, physical addresses, and sexual preferences. The breach was traced to a vulnerability in the sites security system, which allowed attackers to access the user database. The stolen data was later shared on the dark web, exposing users to potential identity theft, hacking, and scams.
