Wordlist Generation

Add likely words to a file (domain name, seasons, employees, etc).

Use hashcat with ruleset to generate the alterations

hashcat --force words.txt -r /usr/share/hashcat/rules/best64.rule --stdout > wordlist.txt

you should also prolly append an exclamation point to the words as well.

Workarounds

“Password must be changed on next logon”

“Password_must_change”

You can try two things

rpcclient -U <user> <IP>
rpcclient $> setuserinfo2 <user> 23 'Password123!'

smbpasswd -U <user> -r <IP>
