Using WinRM on LinuxIf you do not have a Sever Authenticating certificate consult your certicate administrator. On Windows 7 and higher the default port is Open the certificates MMC add-in and confirm the following attributes are correct:.

In Part 1 I showed some of my favorite tools and techniques for popping shells from Kali Linux. In Part 2 I revisited some of the same techniques in Part 1, but performed all the attacks from a Windows machine. I used runas to get a Kerberos TGT for the compromised account and used the built in net commands to explore the domain. Then I used psexec and remote services to get shells and command execution on the target Windows box. Windows Management Instrumentation WMI is the infrastructure for management data and operations on Windows-based operating systems. WMI is an incredibly powerful feature that allows remote querying and administration of Windows devices. From Windows, wmic is the command line interface for querying WMI. Simply typing wmic will drop you into an interactive command prompt where you can query information about the system via WMI. You can also issue queries directly from the command line as well. For example, here I am on a local Windows machine say I got a shell somehow else and dumping information about the system:. For more useful commands, see this Technet article. Now we get to the fun part. Back on our Windows attack box, we can query a domain joined computer for sensitive information using our compromised domain credentials:. Note that we are not starting a service or executing a normal command on the target system that can be logged, or even opening a persistent connection that can be detected. In fact, logging for WMI events is disabled by default, and have to be explicitly turned on. All of the above mentioned aliases can be used remotely. If you have a text file of workstations:. The above examples barely scratch the surface of what WMI is capable of. Not only can you query for all sorts of information, you also have the ability to modify settings and create new objects. Fortunately, a lot of really smart people have wrapped up the best features of WMI for attackers into extremely useful PowerShell scripts. These types of queries are at the heart of a lot of the reconnaissance tools you see included in frameworks like Nishang and PowerSploit. And a second later our Empire listener catches it. On the victim machine, no window opened, no binary was dropped, no service was created, and unless the machine is configured to log WMI-Activity, no easily traceable log was left behind. In fact, you can just drop in to a remote PowerShell session on the machine as if you were using SSH! The easiest way to detect whether WinRM is available is by seeing if the port is opened. WinRM will listen on one of two ports:. We first have to configure our attack machine to work with WinRM as well. From an elevated PowerShell prompt, run the following two commands:. This adds a wildcard to the trustedhosts setting. Be wary of what that entails. You should see some information returned about the protocol version and wsmid:. To remotely run ipconfig and see the output:. Forcing WinRM Open. For example, using PSExec:. Microsoft has implemented a lot of really useful features for sys admins to be able to remotely manage Windows environments. Unfortunately, every one of those tools and techniques can be used and abused by malicious actors or pentesters. Tools like Metasploit, CrackMapExec, and Impacket are incredibly powerful and make a pentesters job so much easier by almost making exploitation point-and-click or whatever the CLI equivalent is - type and click?
GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. A standard SOAP based protocol that allows hardware and operating systems from different vendors to interoperate. Microsoft included it in their Operating Systems in order to make life easier to system administrators. This program can be used on any Microsoft Windows Servers with this feature enabled usually at portof course only if you have credentials and permissions to use it. The purpose of this program is to provide nice and easy-to-use features for hacking. Ruby 2. Depending of your installation method 3 availables the installation of them could be required to be done manually. Another important requirement only used for Kerberos auth is to install the Kerberos package used for network authentication. For some Linux like Debian based Kali, Parrot, etc. For BlackArch it is called krb5 and probably it could be called in a different way for other Linux distributions. If you don't want to put the password in clear text, you can optionally avoid to set -p argument and the password will be prompted preventing to be shown. Just put the already set name of the host after -i argument instead of an IP address. Use filenames on current directory or absolute path. No administrator permissions needed to use this feature. When a ps1 is loaded all its functions will be shown up. To load a ps1 file you just have to type the name auto-completion using tab allowed. The scripts must be in the path set at -s argument. Type menu again and see the loaded functions. Very large files can take a long time to be loaded. Invoke-Binary: allows exes compiled from c to be executed in memory. The name can be auto-completed using tab key. Arguments for the exe file can be passed comma separated. The executables must be in the path set at -e argument. Dll-Loader: allows loading dll libraries in memory, it is equivalent to: [Reflection. Assembly]::Load [IO. File]::ReadAllBytes "pwn.

Microsoft Scripting Guy, Ed Wilson, is here. Sure, cool idea! I recently changed jobs. I am now not only managing and implementing the Windows operating system, but I also have to manage Linux machines, mostly through tools like Puppet, or in this case, Ansible. This was very scary in the beginning—everything is so different. I did. Microsoft did a great job with PowerShell. All of the traditional read older, mature, already present at most companies configuration management tools were born in the Linux universe—none of them on Windows, except maybe System Center Configuration Manager, but I am not going to get into that. Why all on Linux? It was also needed more because most huge installations were run on Linux servers that somehow needed to be managed. This recently changed quite a bit, and the industry found itself in a position where it needed to act. This is why, for example, Chef and Puppet started partnering with Microsoft or the other way around? They are now releasing statement after statement and new modules to support Windows. However, they have chosen to install an agent on Windows, which makes executing code a lot easier. In my current project, I am doing a lot of Ansible coding. They like the others support Windows, but without a local agent installed, and I quite like that idea—especially because I can now run PowerShell commands from my MacBook Pro against a remote Windows operating system. However, there is a module available, written in Python, that wraps WinRM calls and executes them for you. It can easily be installed on your Mac or other Linux system by using this command:. The stage should now be set, and you can ssh into your Linux host or open a terminal on your MacBook and start working. There are two ways we can go from here. Either write a Python script and execute that in a Python environment, or use the command line in Python. I will do the latter for demo purposes. Next I created a winrm. Session object by building the connection string with the HostName parameter and an authentication credential parameter pair. In this case, I am using a Vagrant box with local authentication. We now have the ability to send commands to this session and get data back via the stdout stream. They use a neat little trick here to make it a bit harder to figure out what is being executed via PowerShell—I also suspect to make it a bit more robust. The module encodes the string or PowerShell file into a base64 encoded command and executes that on the remote machine, instead of using a clear text string. I can now execute the following command to find out which Windows features are installed on that remote machine. The point is that I can now also create a folder by applying Desired State Configuration, for example.
