Tool not generating output despite successful execution
Opened this issue · 1 comments
After successfully compiling OffensivePipeline using VS2022 and Buildtools 2022, I attempted to download and obfuscate a tool using the command .\OffensivePipeline.exe t sqlclient as an example.
However, the tool does not generate any output files in the SqlClient_epzktg4zle1 directory despite receiving a successful output - (https://pastebin.com/UPGXPck7)

I also tried to download and execute the file from the releases, but no output was generated as well (I have disabled Windows Defender to eliminate any possible interference).

Any ideas?
Thanks a lot :)
I had the same issue and managed to find the cause and a possible solution:
When the program gets to line 104 in BuildCsharp.cs, the buildSolution.bat file is executed, which contains the msbuild.exe command and its parameters. In case of some tools (like sqlclient), where the target .NET framework is older (for example 4.0), the msbuild fails "silently" with the following:
"The reference assemblies for .NETFramework,Version=v4.0" were not found."
In other words, the error message is simply added to the "standard output" instead of "standard error" and there is no exception raised either. As a result, ExecuteCommand(batPath) returns true as status and the if statement evaluates to false, which causes the execution flow to jump to line 114, saying that there were "No errors".
Since the build failed, there was no file created in the output folder and of course, there was nothing to obfuscate.
The issue can be solved by editing the OffensivePipeline/App.config file so that the BuildCsharpOptions contains a newer target framework version (/p:TargetFrameworkVersion=4.8), like this:
<add key="BuildCsharpOptions" value="/p:TargetFrameworkVersion=4.8 /p:LangVersion=latest /p:Platform="Any CPU" /p:Configuration=Release /p:AllowUnsafeBlocks=true"/>
