+# TryHackMe Box Attacktive Directory(AD) \(Medium\)
+
+## Enumeration
+
+Running a nmap scan we find a lot of open ports, the ports of concern here are 139/445.
+We enumerate the users using enum4linux because it's on port 139/445.
+
+That doesn't work so well. So we can use a tool kerbute to enumerate users in which we find svc-admin and backup
+
+`./kerbute userenum -d spookysec.local -dc spookysec.local -t 5 userlist.txt`
+
+userlist given by tryhackme for reducded execution time.
+
+## ASREPRoasting
+
+Now that we have discovered a several usernames we can use a technique called ASREPRoasting, meaning if a user does not have the Kerberos preauthentication property selected it is possible to retrieve the password hash from that user.
+
+We use /opt/impacket and getNPusers.py script to find the kerberos vuln user.
+`python3 GetNPUsers.py spookysec.local/svc-admin -no-pass`
+
+We get an hash for admin that we might be able to crack. And we get a hit with johnTheRipper.
+
+___svc-admin: management2005___
+
+## SMB Enumeration
+
+Now that we have the admin, we can find out his shares with the domain controller and we find that admin does share backup.
+
+`smbclient -L spookysec.local -U svc-admin`
+
+We enumerate through all the shares but only find the content relevant in this share.
+Enumerating the shares, one had some credentials inside :
+
+`smbclient -L spookysec.local/backup -U svc-admin`
+
+We get the backup_creds file onto our local machine using a `get command`.
+
+The contents of that file looks like base64, decoding it we get the password to backup user.
+
+___backup: backup2517860___
+
+Now that we have the backup share we can dump all the past creds using impacket's __secretdump.py__
+
+## Priv-esc
+
+Now that we are in possession of the Administrator password hash. The next step will be performing a ___Pass the Hash Attack___.
+
+Using a tool _evil-winrm_ we can do this.
+
+`evil-winrm -i spookysec.local -u Administrator -H nt_hash_from_the_secrets_dump`
+
+We got a windows shell now.
+
+Flags for each user account can be located on each user's desktop.
