Netlog

In 2012, a massive data leak occurred on the social networking site Netlog, exposing the personal information of millions of users. The leak compromised 490,383,54 records, including names, email addresses, birthdates, gender, and IP addresses.

The breach was caused by a vulnerability in the sites software, which allowed attackers to access the database containing user data. The leaked information was quickly spread across the internet, putting users at risk of identity theft, spam, and other forms of cybercrime.
