The ouput.txt file is generated with all the NTLM hashes, including repetitions.
BONUS: use the cracked passwords, and add it to the wordlists and crack the NOTFOUND hashes again with rules ;)
Password analysis (Active Directory)
Bonus: run powershell script to get target groups ;)

Via BloodHound or Neo4J
//get all groups
MATCH (g:Group) WHERE g.name CONTAINS 'ADMIN'
RETURN g.name AS GroupName
//get all users from group
Match (u:User)-[:MemberOf]->(g:Group) WHERE g.name CONTAINS "DOMAIN ADMINS" return u.name,g.name
//I like that: get all users from domais like "ADMIN"
Match (u:User)-[:MemberOf]->(g:Group) WHERE g.name CONTAINS "ADMIN" return u.name,g.name
The Neo4J output can be exported as CSV: user,group.
The following script generates group files with target users. We just need to execute it:
