AI-generated summary
The text discusses setting up a GOAD target environment for cybersecurity experiments, using tools like crackmapexec for SMB scanning and network enumeration. It also covers setting up DNS queries, configuring /etc/hosts and Kerberos for Linux, and installing the krb5-user package. The goal is to gather information about the target machines and domains for further analysis and exploitation.

Reconnaissance and Scanning#

Preface#

Recently, I had some time to open my home computer, so I started conducting experiments on the GOAD target environment. The write-up for the GOAD target will first follow the author's process, 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 conducting experiments, 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 is 192.168.56.1/0

image

Thus, the overall access path for the environment is:

Windows (host machine - 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 consumes memory, and my host machine only has 32GB of RAM. If I start another Kali instance, the target machine will report an error due to insufficient memory.

The CPU of the host machine will also spike.

image

So I will directly conduct attacks using Ubuntu. If later the Ubuntu machine does not meet the attack requirements, we will discuss that then!

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 all target machine IPs, names, and domain information.

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 indicate 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's IP#

image

You can use nslookup to perform DNS queries to list relevant information about 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 domain controllers providing LDAP services in the "sevenkingdoms.local" domain.
    • The IP address of the queried DNS server.

Querying sevenkingdoms.local

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 to be reconfigured, you can use dpkg-reconfigure or modify the /etc/krb5.conf file for reconfiguration. The content is 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 above, Kerberos is set up.

Unset the ticket.

unset KRB5CCNAME

Test other domains.

export KRB5CCNAME=/home/lca/tools/impacket/examples/arya.stark.ccache

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

image

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
