With world+dog on Zoom these days, news of a zero-day attack against the videoconferencing app would cause a stir, but relax - it's only if you're on Windows 7 or older. An independent researcher told ACROS Security about the flaw that would allow for remote code execution on any Zoom Client for Windows used by Windows 7, even with extended support after the OS was shuttered in January.
