https://github.com/ropnop/kerbrute/releases/download/v1.0.3/kerbrute_linux_amd64

Download this one. 

chmod +x kerbrute_linux_amd64

./kerbrute_linux_amd64 userenum --dc 10.10.10.192 -d blackfield.local -o valid_users.out allusers.lst

This tool will give you list of users from allusers.lst those are a part of blackfield.local domain. allusers.lst is having some usernames in it. using kerbrute tool we will compare the usernames with AD so that we can know how many valid usernames are there in AD. 

we can also bruteforce to find out users password:

alert: before running this bruteforce command please go through the github page. because if lockout policy and siem tool there then you may get caught. but it is not gonna generate event code 4624, its gonna create a kerberos failure thing which by default not logged. so its a good way to brute force account with potentially just not being seen. 

root@kali:~# ./kerbrute_linux_amd64 bruteuser -d lab.ropnop.com passwords.lst thoffman

thoffman is the username.

 Kape is a triage collection and post-processing application written by Eric Zimmerman. Remember its just the triage collection tool ok? We will analyze the collection later.  https://github.com/EricZimmerman/KapeFiles Kape download: Kroll Artifact Parser And Extractor (KAPE) | Cyber Risk | Kroll Besides full disk image/acquired disk image, this tool allows us to create smaller triage image where important forensic data is present . In case the scenario is divide and conquer , meaning if you want smaller triage image from big size disk image then you can use this and share with your DFIR team to investigate together. The main reason of using kape is now you don't need to wading or sift through into the full image where 10% actual artifacts are present. Kape will allow you to collect those 10% before taking full image. Now you can analysis those 10% of data.  If you want to learn more, please open for508 workbook and labs section 1-2.pdf file and look for page 28. This is...
