In many OSINT investigation scenarios, you'll want to find email addresses for a person or members of an organization. By identifying the target email, you can proceed to contact the target, send a phishing email, or even use one of the emails to social engineer the target from the same organization. For this we can use katana to scrape emails.
Bash:
user@host:~$ katana -u nasa.gov -f email
