Installation and Configuration for Windows Remote ManagementGitHub 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.
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.

The Connect-WSMan cmdlet connects to the WinRM service on a remote computer, and it establishes a persistent connection to the remote computer. However, you can also use this cmdlet to connect to the WinRM service on a remote computer before you change to the WSMan provider. The remote computer appears in the root directory of the WSMan provider. Explicit credentials are required when the client and server computers are in different domains or workgroups. The Connect-WSMan cmdlet is generally used in the context of the WSMan provider to connect to a remote computer, in this case the server01 computer. However, you can use the cmdlet to establish connections to remote computers before you change to the WSMan provider. Those connections appear in the ComputerName list. This command creates a connection to the remote system server01 using the Administrator account credentials. Get-Credential prompts you for a password of username and password through a dialog box or at the command line, depending on system registry settings. Connect-WSMan then connects to the remote system server01 by using the Administrator credentials. This example creates a connection to the remote server01 computer by using the connection options that are defined in the New-WSManSessionOption command. In this case, the session options set a connection time out of 30 seconds 30, milliseconds. Then, Connect-WSMan connects to the remote server01 computer by using the specified session options. Specifies the application name in the connection. The complete identifier for the remote endpoint is in the following format:. Internet Information Services IISwhich hosts the session, forwards requests with this endpoint to the specified application. This parameter is designed to be used if many computers establish remote connections to one computer that is running PowerShell. Specifies the authentication mechanism to be used at the server. The acceptable values for this parameter are:. Caution: CredSSP delegates the user credentials from the local computer to a remote computer. This practice increases the security risk of the remote operation. If the remote computer is compromised, when credentials are passed to it, the credentials can be used to control the network session. Specifies the digital public key certificate X of a user account that has permission to perform this action. Enter the certificate thumbprint of the certificate. Certificates are used in client certificate-based authentication. They can be mapped only to local user accounts; they do not work with domain accounts. Specifies the computer against which to run the management operation. Use the local computer name, use localhost, or use a dot. The local computer is the default. When the remote computer is in a different domain from the user, you must use a fully qualified domain name must be used. You can pipe a value for this parameter to the cmdlet.

Installation directly as ruby gem dependencies will be installed automatically on your system. Method 3. Using bundler dependencies will not be installed on your system, just to use evil-winrm. 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. Load powershell scripts. Assembly]::Load [IO.

Donut-Loader: allows to inject x64 payloads generated with awesome donut technique. No need to encode the payload. You can use this donut-maker to generate the payload.
