“The various websites were all using the same marketing software built by email marketing company Mailfire — who was responsible for the leak.”

The experts discovered that the database was containing copies of push notifications that tens of online sites were sending to their users via Mailfire’s push notification service.

The archive contains 882.1 GB of log files that were being updated in real-time while the notifications were sent out to the users of more than 70 dating sites. The database also contained data from some e-commerce websites, the leak affected individuals from over 100 countries.

Some of the notifications included in the archive contained links to the user’s profile that also contained authentication keys. An attacker could use these URLs to access a user’s profile on the dating site without the knowledge of the password.
