Below you can find some of the most notorious incidents that have occurred in regards to data being leaked. Note that we have not listed every source that has been merged into our database. We have only listed the more known incidents that have been subject to media attention. If you feel that there is a source that should be on this page, feel free to use our contact page and send us further information in regards to the incident and why you believe it should be added to this list.

While we try our best to reference each incident to a reliable media source, it is impossible to do so for all the events. Note that in no way is this list supposed to mark the total amount of sources that we have available, this page should be used for references only.
