Cryptojacking scripts that mine Monero via JavaScript code can also run inside Word files, security researchers have discovered.

This is possible via a new feature added to recent versions of Microsoft Word that allows users to embed Internet videos inside Word files without having to inject the actual video file inside the document itself.

Users can copy-paste a video's iframe embed code inside a Word popup, and the video will appear in the document the next time they open it.

If they press the "Play" button that appears over the video's iframe, the video loads and plays inside a popup.
