A few years ago i have registered with a service called apsense, this service allow the user to connect with other people to increase your network power and one day the owner of firstname.lastname@example.org contacted me. Since i was new to the hacking scene i tested the email against HaveiBeenPwned and found that it was leaked. I download the most obvious database as i knew back then that ClixSense database had the passwords in plain text and got the password.
Here is a step by step...
1 - Checked if the email was leaked at HaveiBeenPwned.
2 - Get info and downloading the database
3 - Decompressing the SQL file
4 - Opening the SQL file with EmEditor
4.1 - Getting the info from the file
5 - Credentials from the raw data
