In the slides (3.2.3 Finding Virtual Hosts) they quickly touch on Fierce. The command they use is “fierce -dns elearnsecurity.com”. This command works on my older Kali VM but not on my newer Kali VM. I’m assuming it’s because Fierce was updated. Does anyone know what the new version of “fierce -dns” is? I checked the man pages and didn’t come across anything. No luck on Google either.
