In this pdf[1] , they discuss security issues in intel chips.They mention strange responses from intel. Also it's possible, but very hard to exploit those issues , which is optimal in this case.

Forgive me if I don't open a PDF from a .ru domain. (and yes, I know how silly that response is)


If you were actually interested in the content, there are countless ways to open a PDF safely.

* Open the PDF in a non-adobe reader such as Foxit and Sumatra w/ JavaScript disabled

* Both FF and Chromes internal PDF viewers ignore JS

* You can preview a PDF in Google drive

* Open the PDF in a sandboxed VM.

Guessing for your history of spammming 1 line pointless comments, you probably already know this.


You are right. I didn't know that PDF.js in Firefox was somewhat safer, though.
