Sharing is caring, so I'll share one of mines. I tend to use google dorking as usual, but also use LeakCheck which is a rather handy tool to receive clear text passwords from Usernames, Email Addresses and such. Are there any other places, like these, that can be of use? :). Source: about 1 year ago
