Your message seems to say that you will be automatically hacked when you open a PDF. Is that true? Not sure how the hacking works. I was guessing that opening a PDF left you open to hacking because of the two security holes, but that didn't mean you'd be automatically hacked.
Separate questions: If you do open a PDF, how long is the "window" for someone to be able to hack you? How would hackers know when you open a PDF, so that they can time their hacking?
I'm not sure I've ever opened PDFs on my iPad, but I'd like to know this stuff, to judge how much risk there actually is. Some of the news reports said that the weaknesses hadn't been exploited so far, but hacking was expected. How can they tell whether any hacking has happened? Is such a statement credible, or more likely PR spin?
