The ultimate WinRM shell for hacking/pentesting
Description & Purpose
This shell is the ultimate WinRM shell for hacking/pentesting.
WinRM (Windows Remote Management) is the Microsoft implementation of WS-Management Protocol. 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 adminsitrators.
This program can be used on any Microsoft Windows Servers with this feature enabled (usually at port 5985), of course only if you have credentials and permissions to use it. So we can say that it could be used in a post-exploitation hacking/pentesting phase. The purpose of this program is to provide nice and easy-to-use features for hacking. It can be used with legitimate purposes by system administrators as well but the most of its features are focused on hacking/pentesting stuff.
- Command History

- SSL and certificates support
Usage: evil-winrm -i IP -u USER [-s SCRIPTS_PATH] [-e EXES_PATH] [-P PORT] [-p PASS] [-U URL] [-S] [-c PUBLIC_KEY_PATH ] [-k PRIVATE_KEY_PATH ] -S, --ssl Enable SSL -c, --pub-key PUBLIC_KEY_PATH Local path to public key certificate -k, --priv-key PRIVATE_KEY_PATH Local path to private key certificate -s, --scripts PS_SCRIPTS_PATH Powershell scripts local path -e, --executables EXES_PATH C# executables local path -i, --ip IP Remote host IP or hostname (required) -U, --url URL Remote url endpoint (default /wsman) -u, --user USER Username (required) -p, --password PASS Password -P, --port PORT Remote host port (default 5985) -V, --version Show version -h, --help Display this help message
Ruby 2.3 or higher is needed. Some ruby gems are needed as well:
stringio >=0.0.2 and
~$ sudo gem install winrm winrm-fs colorize stringio
Installation & Quick Start
- Step 1. Clone the repo:
git clone https://github.com/Hackplayers/evil-winrm.git
- Step 2. Ready. Just launch it!
~$ cd evil-winrm && ruby evil-winrm.rb -i 192.168.1.100 -u Administrator -p 'MySuperSecr3tPass123!' -s '/home/foo/ps1_scripts/' -e '/home/foo/exe_files/'
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.
To use IPv6, the address must be added to /etc/hosts.
Alternative installation method as ruby gem
- Step 1. Install it:
gem install evil-winrm
- Step 2. Ready. Just launch it!
~$ evil-winrm -i 192.168.1.100 -u Administrator -p 'MySuperSecr3tPass123!' -s '/home/foo/ps1_scripts/' -e '/home/foo/exe_files/'
- upload: local files can be auto-completed using tab key. It is recommended to use absolute path for destination to avoid errors. Otherwise you could get uncontrolled errors due Winrm-fs limitations.
upload local_path remote_absolute_path
- download: It is recommended to use absolute paths to avoid errors. Otherwise you could get uncontrolled errors due Winrm-fs limitations.
download remote_absolute_path local_path
Note about paths (upload/download): If the file to download is in the initial remote dir, absolute path on first parameter can be avoided in order to use simple file name. Relative paths are not recommended to use and can cause errors on download/upload. Second argument (destination for upload/download) can be blank and in that case it will be uploaded/downloaded to current local dir or initial (landing dir once connected) remote dir.
services: list all services. No administrator permissions needed.
menu: load the
l04d3r-LoadDllfunctions that we will explain below. When a ps1 is loaded all its functions will be shown up.
Load powershell scripts
To load a ps1 file you just have to type the name (auto-completion usnig tab allowed). The scripts must be in the path set at
-sargument. Type menu again and see the loaded functions.
Invoke-Binary: allows exes compiled from c# to be executed in memory. The name can be auto-completed using tab key and allows up to 3 parameters. The executables must be in the path set at
l04d3r-LoadDll: allows loading dll libraries in memory, it is equivalent to:
The dll file can be hosted by smb, http or locally. Once it is loaded type
menu, then it is possible to autocomplete all functions.
- To disable colors just modify on code this variable
$colors_enabled. Set it to false:
$colors_enabled = false
