I have been trying to implement leaked credentials. I pasted a user's content on dark web sites such as pastebin.com but no alert have been generated yet. Is there any way to get more information about Leaked Credentials alerts that have been triggered. I am not able to see any alert on Risky Users as well as Leaked Alert Policy on Cloud App Security. Please let me know what wrong am i doing here and how can i test leaked credentials for one of my users?
