What is Commando VM?

For penetration testers looking for a stable and supported Linux testing platform, the industry agrees that Kali is the go-to platform. However, if you’d prefer to use Windows as an operating system, you may have noticed that a worthy platform didn’t exist. As security researchers, every one of us has probably spent hours customizing a Windows working environment at least once and we all use the same tools, utilities, and techniques during customer engagements. Therefore, maintaining a custom environment while keeping all our tool sets up-to-date can be a monotonous chore for all. Recognizing that, we have created a Windows distribution focused on supporting penetration testers and red teamers.

Born from our popular FLARE VM that focuses on reverse engineering and malware analysis, the Complete Mandiant Offensive VM (“Commando VM”) comes with automated scripts to help each of you build your own penetration testing environment and ease the process of VM provisioning and deployment. This blog post aims to discuss the features of Commando VM, installation instructions, and an example use case of the platform. Head over to the Github to find Commando VM.

About Commando VM

Penetration testers commonly use their own variants of Windows machines when assessing Active Directory environments. Commando VM was designed specifically to be the go-to platform for performing these internal penetration tests. The benefits of using a Windows machine include native support for Windows and Active Directory, using your VM as a staging area for C2 frameworks, browsing shares more easily (and interactively), and using tools such as PowerView and BloodHound without having to worry about placing output files on client assets.

Commando VM uses Boxstarter, Chocolatey, and MyGet packages to install all of the software, and delivers many tools and utilities to support penetration testing. This list includes more than 140 tools, including:

  • Nmap
  • Wireshark
  • Covenant
  • Python
  • Go
  • Remote Server Administration Tools
  • Sysinternals
  • Mimikatz
  • Burp-Suite
  • x64dbg
  • Hashcat

With such versatility, Commando VM aims to be the de facto Windows machine for every penetration tester and red teamer. For the blue teamers reading this, don’t worry, we’ve got full blue team support as well! The versatile tool sets included in Commando VM provide blue teams with the tools necessary to audit their networks and improve their detection capabilities. With a library of offensive tools, it makes it easy for blue teams to keep up with offensive tooling and attack trends.

How to install Commando VM

Like FLARE VM, we recommend you use Commando VM in a virtual machine. This eases deployment and provides the ability to revert to a clean state prior to each engagement. We assume you have experience setting up and configuring your own virtualized environment. Start by creating a new virtual machine (VM) with these minimum specifications:

  • 60 GB of disk space
  • 2 GB memory

Next, perform a fresh installation of Windows. Commando VM is designed to be installed on Windows 7 Service Pack 1, or Windows 10, with Windows 10 allowing more features to be installed.

Once the Windows installation has completed, we recommend you install your specific VM guest tools (e.g., VMware Tools) to allow additional features such as copy/paste and screen resizing. From this point, all installation steps should be performed within your VM.

Make sure Windows is completely updated with the latest patches using the Windows Update utility. Note: you may have to check for updates again after a restart.

We recommend taking a snapshot of your VM at this point to have a clean instance of Windows before the install.

Go to the following URL and download the compressed Commando virtual machine repository to your virtual machine: https://github.com/fireeye/commando-vm/archive/master.zip

Unzip the downloaded archive to the root of the C drive, that is, the files should be on the path C:\commando-vm-master\:

Open the PowerShell console, to do this, click Win+x and select Windows PowerShell (admin) in the list that opens:

In the console, enter the command

cd C:\commando-vm-master\

Now we need to change the PowerShell execution policy to unrestricted, to do this, run the following command:

Set-ExecutionPolicy unrestricted

When prompted, enter Y.

Run at the command prompt:

./install.ps1

The script will ask the password of the current user – it is needed in order to automatically log into the system during reboots that are performed during installation. You can also pass the password in advance using the option ‘-password <current_password_password>’:

.\install.ps1 -password <пароль>

By the way, if your user does not have a password at all, then just press ENTER during the request.

At the very beginning, the program will do a dependency check:

[+] Checking if script is running as administrator..
        phenomenal cosmic powers
[+] Checking to make sure Operating System is compatible
        Майкрософт Windows 10 Pro supported
[+] Checking if host has been configured with updates
        updates appear to be in order
[+] Checking if host has enough disk space
        > 60 GB hard drive. looks good
[-] Do you need to take a snapshot before continuing? Y/N

The very last question asks if we want to take a snapshot of the system before continuing. Let me remind you that VirtualBox also allows you to take a snapshot of the system – you can take it before installing Commando VM or immediately after installing Commando VM tools. As for this request, it means a snapshot of the OS using the methods of the OS itself. If you need this, enter Y.

The rest of the installation process is fully automated. Depending on the speed of your Internet, the entire installation may take from 2 to 3 hours (in practice, I had to leave the computer turned on for the night, because by that time the installation had already been going on for about 6 hours). The virtual machine will restart several times due to the numerous software installation requirements.

The Commando VM installation process has begun:

Installing Commando VM is on the way:

After the installation is complete, the PowerShell prompt remains open, waiting for any key to be pressed before exiting.

Type ENTER to exit:

After the installation is complete, you will see the following working environment:

At this point, it is recommended that you restart your computer for the change to take effect. After rebooting, you will have a successfully installed Commando VM! It is recommended to turn off the virtual machine and take another snapshot of the system using virtualization software (that is, in VirtualBox, for example) in order to maintain the clean state of the virtual machine for use in future projects.

Hot to install new packages in Commando VM

Commando VM uses the Chocolatey Windows package manager. Therefore, installing new packages is easy. For example, enter the following command as Administrator to deploy Github Desktop on your system:

cinst github

How to update programs in Commando VM

Enter the following command to upgrade all packages to the latest versions:

cup all

Each package will be checked sequentially and if a new version is found, it will be updated. This takes some time, but much less than during installation.

How to hack computers in Windows example

Commando VM is built with the primary focus of supporting internal engagements. To showcase Commando VMs capabilities, we constructed an example Active Directory deployment. This test environment may be contrived; however, it represents misconfigurations commonly observed by Mandiant’s Red Team in real environments.

We get started with Commando VM by running network scans with Nmap.

Looking for low hanging fruit, we find a host machine running an interesting web server on TCP port 8080, a port commonly used for administrative purposes. Using Firefox, we can connect to the server via HTTP over TCP port 8080.

Let’s fire up Burp Suite’s Intruder and try brute-forcing the login. We navigate to our Wordlists directory in the Desktop folder and select an arbitrary password file from within SecLists.

After configuring Burp’s Intruder and analyzing the responses, we see that the password “admin” grants us access to the Jenkins console. Classic.

It’s well known that Jenkins servers come installed with a Script Console and run as NT AUTHORITY\SYSTEM on Windows systems by default. We can take advantage of this and gain privileged command execution.

Now that we have command execution, we have many options for the next step. For now, we will investigate the box and look for sensitive files. Through browsing user directories, we find a password file and a private SSH key.

Let’s try and validate these credentials against the Domain Controller using CredNinja.

Excellent, now that we know the credentials are valid, we can run CredNinja again to see what hosts the user might have local administrative permissions on.

It looks like we only have administrative permissions over the previous Jenkins host, 192.168.38.104. Not to worry though, now that we have valid domain credentials, we can begin reconnaissance activities against the domain. By executing 

runas /netonly /user:windomain.local\niso.sepersky cmd.exe

and entering the password, we will have an authenticated command prompt up and running.

The previous screenshot shows that we can successfully list the contents of the SYSVOL file share on the domain controller, confirming our domain access. Now we start up PowerShell and start share hunting with PowerView.

We are also curious about what groups and permissions are available to the user account compromised. Let’s use the Get-DomainUser module of the post-exploitation framework PowerView to retrieve user details from Active Directory. Note that Commando VM uses the “dev” branch of PowerView by default.

We also want to check for further access using the SSH key we found earlier. Looking at our port scans we identify one host with TCP port 22 open. Let’s use MobaXterm and see if we can SSH into that server.

We access the SSH server and also find an easy path to rooting the server. However, we weren’t able to escalate domain privileges with this access. Let’s get back to share hunting, starting with that hidden Software share we saw earlier. Using File Explorer, it’s easy to browse shares within the domain.

Using the output from PowerView’s Invoke-ShareFinder command, we begin digging through shares and hunting for sensitive information. After going through many files, we finally find a config.ini file with hardcoded credentials.

Using CredNinja, we validate these credentials against the domain controller and discover that we have local administrative privileges!

Let’s check group memberships for this user.

Lucky us, we’re a member of the “Domain Admins” group!

Windows hackers programs (Commando VM Tools)

Active Directory Tools

  • Remote Server Administration Tools (RSAT)
  • SQL Server Command Line Utilities
  • Sysinternals — Whether you’re an IT Pro or a developer, you’ll find Sysinternals utilities to help you manage, troubleshoot and diagnose your Windows systems and applications.

Command & Control

  • Covenant is a .NET command and control framework that aims to highlight the attack surface of .NET, make the use of offensive .NET tradecraft easier, and serve as a collaborative command and control platform for red teamers. Covenant is an ASP.NET Core, cross-platform application that includes a web-based interface that allows for multi-user collaboration.
  • PoshC2 is a proxy aware C2 framework that utilises Powershell and/or equivalent (System.Management.Automation.dll) to aid penetration testers with red teaming, post-exploitation and lateral movement. Powershell was chosen as the base implant language as it provides all of the functionality and rich features without needing to introduce multiple third party libraries to the framework.
  • WMImplant is a PowerShell based tool that is designed to act like a RAT. Its interface is that of a shell where any command that is supported is translated into a WMI-equivalent for use on a network/remote machine. WMImplant leverages WMI to both perform actions against targeted machines, but also as the C2 channel for issuing commands and receiving results. WMImplant will likely require local administrator permissions on the targeted machine.
  • WMIOps is a powershell script that uses WMI to perform a variety of actions on hosts, local or remote, within a Windows environment. It's designed primarily for use on penetration tests or red team engagements.

Developer Tools

  • Dep
  • Git
  • Go
  • Java
  • Python 2
  • Python 3 (default)
  • Ruby
  • Ruby Devkit
  • Visual Studio 2017 Build Tools (Windows 10)
  • Visual Studio Code

Evasion

  • CheckPlease — sandbox evasion modules written in PowerShell, Python, Go, Ruby, C, C#, Perl, and Rust.
  • Demiguise. The aim of this project is to generate .html files that contain an encrypted HTA file. The idea is that when your target visits the page, the key is fetched and the HTA is decrypted dynamically within the browser and pushed directly to the user. This is an evasion technique to get round content / file-type inspection implemented by some security-appliances. This tool is not designed to create awesome HTA content. There are many other tools/techniques that can help you with that. What it might help you with is getting your HTA into an environment in the first place, and (if you use environmental keying) to avoid it being sandboxed.
  • DefenderCheck. Identifies the bytes that Microsoft Defender flags on. Quick tool to help make evasion work a little bit easier. Takes a binary as input and splits it until it pinpoints that exact byte that Microsoft Defender will flag on, and then prints those offending bytes to the screen. This can be helpful when trying to identify the specific bad pieces of code in your tool/payload.
  • DotNetToJScript. A tool to create a JScript file which loads a .NET v2 assembly from memory.
  • Invoke-CradleCrafter is a PowerShell v2.0+ compatible PowerShell remote download cradle generator and obfuscator.
  • Invoke-DOSfuscation. Cmd.exe Command Obfuscation Generator & Detection Test Harness
  • Invoke-Obfuscation. Invoke-Obfuscation is a PowerShell v2.0+ compatible PowerShell command and script obfuscator.
  • Invoke-Phant0m. Windows Event Log Killer. This script walks thread stacks of Event Log Service process (specific svchost.exe) and identify Event Log Threads to kill Event Log Service Threads. So the system will not be able to collect logs and at the same time the Event Log Service will appear to be running.
  • Not PowerShell (nps). Not PowerShell
  • PS>Attack. A tool for building PS>Attack, an offensive PowerShell console that makes it easy for pentesters to use PowerShell. A tool that makes it easy to compile a custom version of PS>Attack, a portable powershell attack environment. What does the PS>Attack Build Tool do? The build tool downloads the latest version of PS>Attack and the latest versions of tools that is uses (PowerSploit, Powercat, Inveigh, etc), obfuscates them with @danielbohannon's Invoke-Obfuscation and then encrypts them with a custom key. It then replaces certain identifable strings within the PS>Attack source code with random strings and then compiles everything, producing a custom version of PS>Attack that's up to date and consists of unique file signatures, making it very difficult for Antivirus and Incident Response teams to find.
  • PSAmsi is a tool for auditing and defeating AMSI signatures. It's best utilized in a test environment to quickly create payloads you know will not be detected by a particular AntiMalware Provider, although it can be useful in certain situations outside of a test environment. When using outside of a test environment, be sure to understand how PSAmsi works, as it can generate AMSI alerts.
  • Pafishmacro. Pafish Macro is a Macro enabled Office Document to detect malware analysis systems and sandboxes. It uses evasion & detection techniques implemented by recent malicious documents found in the public. The VBS / VBA code is open source, you can study the code of all evasion tricks.
  • PowerLessShell. Run PowerShell command without invoking powershell.exe. PowerLessShell rely on MSBuild.exe to remotely execute PowerShell scripts and commands without spawning powershell.exe. You can also execute raw shellcode using the same approach. To add another layer of crap the payload will copy msbuild.exe to something random and build the payload using the randomly generated binary. You can provide -knownprocess switch to use known Windows process name instead of renaming MsBuild.exe to something random
  • PowerShdll. Run PowerShell with rundll32. Bypass software restrictions. Run PowerShell with dlls only. Does not require access to powershell.exe as it uses powershell automation dlls. PowerShdll can be run with: rundll32.exe, installutil.exe, regsvcs.exe, regasm.exe, regsvr32.exe or as a standalone executable.
  • StarFighters. A JavaScript and VBScript Based Empire Launcher, which runs within their own embedded PowerShell Host. Both Launchers run within their own embedded PowerShell Host, so we don't need PowerShell.exe. This might be usefull when a company is blocking PowerShell.exe and/or is using a Application Whitelisting solution, but does not block running JS/VBS files.

Exploitation

  • ADAPE-Script. Active Directory Assessment and Privilege Escalation Script
  • API Monitor is a free software that lets you monitor and control API calls made by applications and services. Its a powerful tool for seeing how applications and services work or for tracking down problems that you have in your own applications.
  • CrackMapExec. A swiss army knife for pentesting networks. CrackMapExec (a.k.a CME) is a post-exploitation tool that helps automate assessing the security of large Active Directory networks. Built with stealth in mind, CME follows the concept of "Living off the Land": abusing built-in Active Directory features/protocols to achieve it's functionality and allowing it to evade most endpoint protection/IDS/IPS solutions. CME makes heavy use of the Impacket library (developed by @asolino) and the PowerSploit Toolkit (developed by @mattifestation) for working with network protocols and performing a variety of post-exploitation techniques. Although meant to be used primarily for offensive purposes (e.g. red teams), CME can be used by blue teams as well to assess account privileges, find possible misconfigurations and simulate attack scenarios.
  • CrackMapExecWin. The great CrackMapExec tool compiled for Windows.
  • DAMP. The Discretionary ACL Modification Project: Persistence Through Host-based Security Descriptor Modification. This project contains several files that implement host-based security descriptor "backdoors" that facilitate the abuse of various remotely accessible services for arbitrary trustees/security principals. tl;dr - this grants users/groups (local, domain, or 'well-known' like 'Everyone') of an attacker's choosing the ability to perform specific administrative actions on a modified host without needing membership in the local administrators group. Note: to implement these backdoors, you need the right to change the security descriptor information for the targeted service, which in stock configurations nearly always means membership in the local administrators group.
  • EvilClippy. A cross-platform assistant for creating malicious MS Office documents. Can hide VBA macros, stomp VBA code (via P-Code) and confuse macro analysis tools. Runs on Linux, OSX and Windows.
  • Exchange-AD-Privesc. Exchange privilege escalations to Active Directory. This repository provides a few techniques and scripts regarding the impact of Microsoft Exchange deployment on Active Directory security.
  • FuzzySec's PowerShell-Suite. A collection of tools for solving various problems in PowerShell.
  • FuzzySec's Sharp-Suite. A collection of C # code examples.
  • Generate-Macro. This Powershell script will generate a malicious Microsoft Office document with a specified payload and persistence method. [!] This script will temporarily disable 2 macro security settings while creating the document. [!] The idea is to generate your malicious document on a development box you OWN and use that document to send to a target.
  • GhostPack
  • Rubeus is a C# toolset for raw Kerberos interaction and abuses. It is heavily adapted from Kekeo project and MakeMeEnterpriseAdmin project. Rubeus also uses a C# ASN.1 parsing/encoding library named DDer.
  • SafetyKatz is a combination of slightly modified version of @gentilkiwi's Mimikatz project and @subtee's .NET PE Loader. First, the MiniDumpWriteDump Win32 API call is used to create a minidump of LSASS to C:\Windows\Temp\debug.bin. Then @subtee's PELoader is used to load a customized version of Mimikatz that runs sekurlsa::logonpasswords and sekurlsa::ekeys on the minidump file, removing the file after execution is complete.
  • Seatbelt is a C# project that performs a number of security oriented host-survey "safety checks" relevant from both offensive and defensive security perspectives.
  • SharpDPAPI is a C# port of some Mimikatz DPAPI functionality.
  • SharpDump is a C# port of PowerSploit's Out-Minidump.ps1 functionality. The MiniDumpWriteDump Win32 API call is used to create a minidump for the process ID specified (LSASS by default) to C:\Windows\Temp\debug.out, GZipStream is used to compress the dump to C:\Windows\Temp\debug.bin (.gz format), and the original minidump file is deleted.
  • SharpRoast is a C# port of various PowerView's Kerberoasting functionality. This project has now been deprecated. Its functionality has been incorporated into Rubeus via the "kerberoast" action, which provides proper ASN.1 structure parsing.
  • SharpUp is a C# port of various PowerUp functionality. Currently, only the most common checks have been ported; no weaponization functions have yet been implemented.
  • SharpWMI is a C# implementation of various WMI functionality. This includes local/remote WMI queries, remote WMI process creation through win32_process, and remote execution of arbitrary VBS through WMI event subscriptions. Alternate credentials are also supported for remote methods.
  • GoFetch is a tool to automatically exercise an attack plan generated by the BloodHound application. GoFetch first loads a path of local admin users and computers generated by BloodHound and converts it to its own attack plan format. Once the attack plan is ready, GoFetch advances towards the destination according to plan step by step, by successively applying remote code execution techniques and compromising credentials with Mimikatz.
  • Impacket is a collection of Python classes for working with network protocols. Impacket is focused on providing low-level programmatic access to the packets and for some protocols (e.g. SMB1-3 and MSRPC) the protocol implementation itself. Packets can be constructed from scratch, as well as parsed from raw data, and the object oriented API makes it simple to work with deep hierarchies of protocols. The library provides a set of tools as examples of what can be done within the context of this library.
  • impacket-examples-windows
  • Invoke-ACLPwn is a tool that automates the discovery and pwnage of ACLs in Active Directory that are unsafe configured. Invoke-ACLpwn is designed to run with integrated credentials as well as with specified network credentials. The script works by creating an export of all ACLs in the domain with SharpHound as well as the group membership of the user account that the tool is running under. If the user does not already have writeDACL permissions on the domain object, the tool will enumerate all ACEs of the ACL of the domain. Every identity in an ACE has an ACL of its own, which is added to the enumeration queue. If the identity is a group and the group has members, every group member is added to the enumeration queue as well. It may take some time to calculate and parse every ACL, but could end up with a "chain" that leads to domain administrative privilges in the target domain.

Password Attacks

  • ASREPRoast. Project that retrieves crackable hashes from KRB5 AS-REP responses for users without kerberoast preauthentication enabled. This project has now been deprecated. Its functionality has been incorporated into Rubeus via the "asreproast" action, which utilizes a more minimal ASN.1 parsing library.
  • CredNinja. A multithreaded tool designed to identify if credentials are valid, invalid, or local admin valid credentials within a network at-scale via SMB, plus now with a user hunter This tool is intended for penetration testers who want to perform an engagement quickly and efficiently. While this tool can be used for more covert operations (including some additions below), it really shines when used at the scale of a large network. At the core of it, you provide it a list of credentials you have dumped (or hashes, it can pass-the-hash) and a list of systems on the domain (I suggest scanning for port 445 first, or you can use "--scan"). It will tell you if the credentials you dumped are valid on the domain, and if you have local administrator access to a host. See below for additional features, like user hunting and host detail enumeration.
