Nmap TCP Full - Enumeration and Initial Exploit Review of Open Ports We will then extract a copy of the NTDS.dit file from the shadow copy and then dump all the hashes in the domain.įinally, we will perform a pass-the-hash attack with the domain admin account to get an elevated shell and grab the flags. Once we have a foothold, we will find that this account has the SeBackupPrivilege enabled, which we will utilize to create a shadow copy of the C:\ drive. Inside the share we will find an LSASS.zip file that we will dump using Pypykatz, extracting the NTLM hash for a third account.Īfter obtaining the NTLM hash for a third account, we will perform a pass-the-hash attack using evil-winrm to gain a foothold on the victim.

After that, we will find that the user we set the password for has access to a share that we couldn’t access earlier. With this information, we will change the account’s password using rpcclient. With a set of valid credentials, we will run Bloodhound.py to enumerate the AD rights and relations, which reveal that our current user has the ForceChangePassword rights over another account in the domain.

After we AS-REP roast the user, we will dump their NetNTLMv2 hash and crack it using hashcat. We will begin by enumerating all of the users in the domain through the profiles$ share and find that one of them is vulnerable to an AS-REP roast attack. In this Walkthrough, we will be hacking the machine Blackfield from HackTheBox.
