Pardon my ignorance about this, and I will do my own research, but do these hidden formattings/stego/call-home functions disappear, get mutilated, become broken when ‘converting’ such PDF documents to other document types via use of many ‘conversion’ tools (Calibre comes to mind instantly) or are these embedded organisms a persistent across any automated conversion routine?
