Let's recap what we have learned in this section.
The first thing that you always have to do is to collect all the usernames that you have found on different
social media accounts or different online accounts.
This will help you to focus on these usernames without you getting distracted.
After you collect all the usernames, you can use search engines to search for these usernames, so
you can use the internal search operator to see whether a certain username has been used in a certain
URL that is indexed by search engines.
Next, you can use people search engine or online tools to find additional accounts with the same username.
So we have learned how we can use ID crawl to search by username to find some social media accounts
that we were not aware of, and we have learned how we can use What's My Name and Blackbird to find
more accounts that we didn't find before.
And we will cover people's search engine in depth in the next section.
And the last thing that you want to do is to search for this username in leaked databases.
And once you identify in which data leak or data breach this username has been found, then you can
either search for this username on the hashed, or you can download the database or the data leak and
search for this username and find any additional information that are associated with this username.
