Can hackers catch data in transfer from JavaScript to native host app and back? Edit: merging in a better-worded question: How secure is stdio data transfer ? Is there a way for man-in-middle attack for such data transfer ? 回答1: It is, in principle, possible to inspect stdio calls made by an executable. For
