AI-generated summary
The text discusses setting up a GOAD target environment for cybersecurity experiments. It includes steps for network configuration, using CrackMapExec (CME) for SMB scanning, and setting up Kerberos on a Linux machine. The author also provides information on DNS queries to find domain controllers and configuring the /etc/hosts file. The goal is to gather useful information about target machines for further exploitation.

Reconnaissance and Scanning#

Preface#

Recently, I had some time to open my home computer, so I started experimenting with the GOAD target environment. The write-up for the GOAD target will follow the author's process first, and later I can add my own understanding and supplements after learning.

For environment setup, refer to the previous blog: https://lca.xlog.app/game-of-active-directoryGOAD-yu-huan-jing-da-jian

Before starting the experiment, take a snapshot of the VM.

Start all machines.

Network settings for the environment.

image

Ubuntu: The IP range for the VirtualBox VM is: 192.168.31.0/24
VirtualBox: The IP range for the GOAD target environment is 192.168.56.1/0

image

Thus, the overall access path for the environment is:

Windows (host IP: 192.168.31.151) -> Ubuntu (VM IP: 192.168.31.142) -> GOAD target (VirtualBox VM IP: 192.168.56.1/24)

I initially wanted to use Kali as the attack machine, but as mentioned in previous article comments, it would be inaccessible and would require a proxy for testing. However, running Kali would consume memory, and my host machine only has 32GB of RAM. If I start another Kali, the target machine would throw an error due to insufficient memory.

The CPU of the host machine would also spike.

image

So I decided to directly conduct attacks on Ubuntu. If the Ubuntu machine does not meet the attack requirements later, we can discuss that!

Network Enumeration#

image

cme

# Install cme
sudo snap install crackmapexec

# cme smb scan
crackmapexec smb 192.168.56.0/24

image

The results of the cme scan are shown in the image above, returning some useful information, including the IPs, names, and domain information of all target machines.

SMB         192.168.56.10   445    KINGSLANDING     [*] Windows 10.0 Build 17763 x64 (name:KINGSLANDING) (domain:sevenkingdoms.local) (signing:True) (SMBv1:False)
SMB         192.168.56.12   445    MEEREEN          [*] Windows Server 2016 Standard Evaluation 14393 x64 (name:MEEREEN) (domain:essos.local) (signing:True) (SMBv1:True)
SMB         192.168.56.22   445    CASTELBLACK      [*] Windows 10.0 Build 17763 x64 (name:CASTELBLACK) (domain:north.sevenkingdoms.local) (signing:False) (SMBv1:False)
SMB         192.168.56.11   445    WINTERFELL       [*] Windows 10.0 Build 17763 x64 (name:WINTERFELL) (domain:north.sevenkingdoms.local) (signing:True) (SMBv1:False)
SMB         192.168.56.23   445    BRAAVOS          [*] Windows Server 2016 Standard Evaluation 14393 x64 (name:BRAAVOS) (domain:essos.local) (signing:False) (SMBv1:True)
  • north.sevenkingdoms.local (2 IPs)
    • CASTELBLACK 192.168.56.22
    • WINTERFELL 192.168.56.11
  • sevenkingdoms.local (1 IP)
    • KINGSLANDING 192.168.56.10
  • essos.local (2 IPs)
    • MEEREEN 192.168.56.12
    • BRAAVOS 192.168.56.23

From the topology, it is clear that the GOAD target has three domains. The cme scan results also show that the DC signatures are all True (signing). In a real environment, to prevent NTLM relay attacks, all signatures must be set to True.

Finding the DC IP#

image

You can use nslookup to perform DNS queries to list the relevant information of the DC.

nslookup -type=srv _ldap._tcp.dc._msdcs.sevenkingdoms.local 192.168.56.10
  • nslookup: DNS query tool
    • -type=srv: Specifies to query SRV records, which are a type of DNS record used to identify specific services.
    • _ldap._tcp.dc._msdcs.sevenkingdoms.local: The hostname to query for information about the domain controller providing LDAP services in the "sevenkingdoms.local" domain.
    • The IP address of the DNS server being queried.

Querying north.sevenkingdoms.local

nslookup -type=srv _ldap._tcp.dc._msdcs.north.sevenkingdoms.local 192.168.56.10

Querying essos.local

nslookup -type=srv _ldap._tcp.dc._msdcs.north.essos.local 192.168.56.10

Setting /etc/hosts and Kerberos#

To use Kerberos in a Linux environment, some settings need to be made.

  1. Configure the /etc/hosts file to set DNS.
# /etc/hosts
# GOAD
192.168.56.10   sevenkingdoms.local kingslanding.sevenkingdoms.local kingslanding
192.168.56.11   winterfell.north.sevenkingdoms.local north.sevenkingdoms.local winterfell
192.168.56.12   essos.local meereen.essos.local meereen
192.168.56.22   castelblack.north.sevenkingdoms.local castelblack
192.168.56.23   braavos.essos.local braavos

image

Install the Kerberos Linux client.

sudo apt install krb5-user

image

image

Set admin_server to meereen.essos.local.

If krb5-user is already installed or needs reconfiguration, you can use dpkg-reconfigure or modify the /etc/krb5.conf file for reconfiguration, as follows:

sudo gedit /etc/krb5.conf

[libdefaults]
	default_realm = essos.local
	kdc_timesync = 1
	ccache_type = 4
	forwardable = true
	proxiable = true
	fcc-mit-ticketflags = true

[realms]
	north.sevenkingdoms.local = {
		kdc = winterfell.north.sevenkingdoms.local
		admin_server = winterfell.north.sevenkingdoms.local
	}

	sevenkingdoms.local = {
		kdc = kingslanding.sevenkingdoms.local
		admin_server = kingslanding.sevenkingdoms.local
	}

	essos.local = {
		kdc = meereen.essos.local
		admin_server = meereen.essos.local
	}

After completing the Kerberos setup, you can try to see if you can obtain a TGT ticket.

As shown, Kerberos is set up.

Unset the ticket.

unset KRB5CCNAME

Test other domains.

[-] [Errno Connection error (winterfell.north.servenkingdoms.local:445)] [Errno -3] Temporary failure in name resolution

I don't know why Kerberos does not work when using the full FQDN for Winterfell, but it works fine when just setting Winterfell instead of winterfell.north.sevenkingdoms.local.

Nmap Scan#

Install nmap.

sudo apt install nmap

Use nmap to perform a scan with the following parameters.

nmap -Pn -p- -sC -sV -oA full_scan_goad 192.168.56.10-12,22-23

Parameters are as follows:

  • -Pn: Do not perform ping scan.
  • -p-: Full port scan, 1-65535.
  • -sC: Run default detection scripts.
  • -sV: Perform service version detection on specified ports.
  • -oA: Output results in three formats.

The nmap scan results are as follows:

# Nmap 7.80 scan initiated Sun May  5 16:44:49 2024 as: nmap -Pn -p- -sC -sV -oA full_scan_goad 192.168.56.10-12,22-23
