Technical notes, AD pentest methodology, list of tools, scripts and Windows commands that I find useful during internal penetration tests and assumed breach exercises (red teaming).
The output files included here are the results of tools, scripts and Windows commands that I ran against a vulnerable Windows AD lab that I created to test attacks/exploits and deliver hands-on penetration testing training sessions to security auditors at my job.
- Step 1. Bypassing Network Access Control (NAC) - if any
- Step 2. Reconnaissance
- Step 3. Gaining access
- Step 4. Post-exploitation and local privilege escalation
- Step 5. Network lateral movement and privileged accounts hunting
- Step 6. Windows domain compromise (Privilege escalation to become 'Domain Admin' + Persistence)
- Step 7. Forest root domain compromise (Privilege escalation to become 'Enterprise Admin')
- Others
If a NAC solution is implemented, the purpose of this phase will be to bypass it to get access to the internal network and start the internal penetration test.
1. Pre-connect scenario => NAC checks are made before granting any access to the internal network
-------------------------------------------------------------------------------------------------
➤ MAC address spoofing technique
- Bypass MAC address filtering solution by spoofing the MAC address of a whitelisted device (e.g. printer, smart TV in meeting room, VOIP phone)
➤ Pre-authenticated device technique
- Bypass wired network 802.1x protection (NAC) by placing a rogue device (with 2 network adapters) between a pre-authenticated device and the network switch.
Using scripts like 'fenrir-ocd' or 'nac_bypass-setup.sh', the traffic will then flow through the rogue device which will be able to log into the network and smuggle network packets.
➤ Captive portal bypass technique
- Hack the captive authentication portal used to control network access
➤ VOIP hopping and VLAN hopping techniques
➤ ...
2. Post-connect scenario => Network access is temporarily granted while NAC checks are ran against your laptop
--------------------------------------------------------------------------------------------------------------
➤ MAC address randomization technique
- Change your MAC address automatically (e.g. every minute) with a script to obtain a new IP address prior getting blocked
and keep accessing the network resources.
➤ ...
The purpose of the reconnaissance phase is to gather as much as possible information about the targets (Windows domains and internal network). It includes Windows domain(s) enumeration, DNS enumeration, targeted network scans...
1. Black-box penetration test (we start with no account)
--------------------------------------------------------
➤ On our laptop connected to the LAN or Wifi, we run commands like 'ipconfig /all', 'ip a' and 'nslookup' to identify:
- the IP address range of the user network (our laptop IP address is part of it)
- the IP address range of a production (server) network/VLAN (thanks to the IP address of the DNS server which is usually also the IP address of a Domain Controller)
➤ Network sniffing
➤ Reconnaissance using DNS queries (e.g. reverse IP lookup, DNS zone transfer) and the naming convention of the hostnames
Examples:
- Domain Controllers have often a hostname like 'pr<bla>dc1', 'dv<bla>ad2', 'usdc02', 'prodfrdc3', etc.
- Web servers have often a hostname like 'prweb01', 'wwwserver02', 'win2k16iis03', 'devJBOSS04', etc.
- Database servers have often a hostname like 'sqlsrv01', 'prdbserver02', 'prodorasrv08', 'devmongodb14', etc.
- Citrix servers have often a hostname like 'prctxsrv1', 'printctx02', 'citrixsrv02', etc.
➤ Targeted network scans (e.g. Nmap and NSE scripts)
2. Grey-box penetration test (we start with 1 low-privileged Windows account)
-----------------------------------------------------------------------------
➤ AD and Windows domain information gathering (enumerate accounts, groups, computers, ACLs, password policies, GPOs, Kerberos delegation, ...)
➤ Numerous tools and scripts can be used to enumerate a Windows domain

- Windows native DOS and Powershell commands (e.g. 'net' commands, PowerShell ActiveDirectory module)
- Sysinternals tools (e.g. ADexplorer.exe)
- PowerView framework / SharpView
- Powershell scripts like ADrecon.ps1
- BloodHound
- PingCastle
- ADCollector
The purpose of this phase is to gain (unauthorized) access to several internal systems (e.g. servers, file shares, databases) by exploiting common security issues such as: default/weak passwords, OS security misconfiguration, insecure network protocols and unpatched known vulnerabilities.

➤ ...
The purpose of the post-exploitation phase is to determine the value of the systems compromised during the previous phase (e.g. sensitivity of the data stored on it, usefulness in further compromising the network) and to escalate privileges to harvest credentials (e.g. to steal the password of a privileged account from the memory of a Windows server/laptop). During this phase, the system(s) compromised can be set-up as a pivot to reach machines that are located in other networks.
1. Windows local privilege escalation to become local administrator and/or "NT AUTHORITY\SYSTEM"

The purpose of the lateral movement phase is to identify Windows servers and laptops on which high privileged user and service accounts are logged (e.g. administrator of all servers, administrator of all workstations/laptops, Domain Admin account). Then try to log into these Windows servers and laptops (for example by re-using the credentials harvested during the previous phase) and take over the high privileged accounts using various hacking techniques (e.g., dumping credentials from memory, token impersonation).

STEP 6. WINDOWS DOMAIN COMPROMISE (Privilege escalation to become "Domain Admin" + Persistence) 🔥🧑🏼💻
The purpose of this phase is to take full control over the target Windows domain.
1. Privilege escalation to become "Domain Admin"
------------------------------------------------
➤ Dumping from a Windows server's memory the clear-text password (or hash) of an account member of the group 'Domain Admins' or 'Administrators' of the Domain Controller
➤ Exploiting AD / Windows domain security misconfiguration
Examples:
- abusing weak ACL or GPO permissions
- abusing LAPS misconfiguration
- exploiting password reuse issues
> the same password is used to protect multiple high privileged accounts and low-privileged accounts

➤ Exploiting an unpatched vulnerability on a DC with a public exploit available (e.g. CVE-2020-1472 Zerologon, risky to run in a production environment)
➤ Hack the Hypervisor (e.g. vCenter) on which the Domain Controllers are running, then perform a snapshot of the DCs, copy/download their memory dump files (.vmsn & .vmem) and finally extract the password hashes of high privileged acccounts (e.g. Domain Admins, Administrators of DC, krbtgt account)
➤ Kerberos Unconstrained Delegation attack (+ Printer Bug or PetitPotam)

➤ Modify temporarily the ACLs to allow an account that you control to perform DCsync attack.
➤ ...
The purpose of this phase is to take full control over the Forest root domain and all the other domains in the target network.
➤ Forge a Kerberos Golden Ticket (TGT) with a 'SID History' for the Forest 'Enterprise Admins' group
➤ Forge an inter-realm trust ticket (cross-domain trust kerberos ticket) and then create TGS for the services LDAP/CIFS/HOST/... in the parent domain
➤ Take over other Windows domains due to password re-use across domains for high privileged accounts
➤ Take over other Windows domains thanks to AD Forest Trusts and/or misconfiguration (e.g. the group 'Domain Admins' of the domain A is member of the group 'Domain Admins' of the domain B)
➤ ...
