[RomuDeuxfois]

Description

When I launch an executable file and there are an error in the execution, the inject status is: INJECT EXECUTED.

My payload:

$url = "https://redcanary.com/wp-content/uploads/Atomic-Red-Team-Logo.png"
$imgLocation = "$env:TEMP\T1491.001-newWallpaper.png"
$orgWallpaper = "C:\Users\RomualdLemesle\Pictures\joker-batman-the-dark-knight-heath-ledger-wallpaper-preview.jpg"
$orgWallpaper | Out-File -FilePath "$env:TEMP\T1491.001-OrginalWallpaperLocation"
$updateWallpapercode = @'
using System.Runtime.InteropServices;
namespace Win32{

    public class Wallpaper{
        [DllImport("user32.dll", CharSet=CharSet.Auto)]
         static extern int SystemParametersInfo (int uAction , int uParam , string lpvParam , int fuWinIni) ;
         
         public static void SetWallpaper(string thePath){
            SystemParametersInfo(20,0,thePath,3);
        }
    }
}
'@

$wc = New-Object System.Net.WebClient
try {
    $wc.DownloadFile($url, $imgLocation)

    # Vérifier et ajouter le type si nécessaire
    if (-not ("Win32.Wallpaper" -as [type])) {
        Add-Type -TypeDefinition $updateWallpapercode
    }

    [Win32.Wallpaper]::SetWallpaper($imgLocation)
}
catch [System.Net.WebException] {
    Write-Host("Cannot download $url")

    if (-not ("Win32.Wallpaper" -as [type])) {
        Add-Type -TypeDefinition $updateWallpapercode
    }

    [Win32.Wallpaper]::SetWallpaper($imgLocation)
}
finally {
    $wc.Dispose()
}

The result in UI:
