Have I Been Breached or Leaked?

About the project

Who is behind the project?

We are a group of security-minded practitioners at 4iQ, passionate about discovering breached or leaked information, understanding and validating the data, and making the results publicly known in order to better protect the community.

What is the purpose of this site?

We want to raise awareness on the growing number of leaks and breaches that are taking place every day.

What is the source of your information?

We constantly monitor bad actor sites and other open sources for potential leak and breach exposures and compile them in a searchable database.

How does all of this work?

It’s all because of open source software! The services are set up on Amazon and we use MongoDB for the database management. The rest of utilities are all licensed with GNU/GPL

We use an engine that takes care of the almost instant collection of any leak that is published on Pastebin, Slexy, Pastie, and other sites on the Deep Web. There is also a separate engine that takes care of reading documents with formats such as .pdf, .doc, .xls, .sqlite, .pst. .mbox, .etc from the large leaks that include various kinds of files.
