Copy the hash into a file named asrep_hash.txt . For many this is the "aha!" moment of the box. We can crack it using with mode 18200 (Kerberos 5 AS-REP etype 23): forest hackthebox walkthrough best

We can query the LDAP service without authentication. This confirms the structure of the domain and returns a vast amount of information:
Once imported, find the svc-alfresco node, right-click it, and mark it as "Owned". Then, in the "Analysis" tab, run the "Shortest Path to High Value Targets" query. The resulting graph will reveal the abuse path:
The is the best starting point for AD testing because it clearly illustrates the chain of exploitation: Enumeration found a misconfigured user. AS-REP Roasting cracked the user's password. Privilege Enumeration identified group misconfigurations. DCSync allowed domain domination. Defensive Takeaways: for users
Once you have a list of usernames, you look for accounts that do not require Kerberos pre-authentication.
Almost immediately, the script returns a hit for the svc-alfresco account:
This will generate a zip file. Download this zip file back to our attacker machine using evil-winrm : For many this is the "aha
