What is the security breach that occurred with Adult Friend Finder?

In October 2016, the Adult Friend Finder network suffered a massive security breach when hackers exploited a vulnerability to gain access to the personal information of over 400 million user accounts across six databases. The compromised data included email addresses, passwords, which were encrypted but with weak protection, and various other sensitive details. This incident became one of the largest data breaches ever recorded at the time. It highlighted significant flaws in the company's cybersecurity practices and raised grave concerns regarding user privacy in the online dating industry. The aftermath of the breach necessitated an urgent review and overhaul of security measures for websites holding sensitive personal information.
