Highlighted as the largest reported data leakage as of January 2024 , the CAM4 data breach in March 2020 occurred as a result of someone at CAM4 misconfiguring Elasticsearch , an internal search engine used by employees to scan user and activity logs . Someone within the organisation unfortunately put the database online without any password protection , leaving data vulnerable to anyone with an IP address .

The nearly-11 billion records in the CAM4 data leak included sensitive user information , including first and last names , email addresses , password hashes , gender and sexual orientation and usernames , chat logs and IP addresses , amongst other information .

A cyberattack at such a large scale highlights the growing need for strong cybersecurity measures within organisations around the world so that they can mitigate against potential data leaks .
