>I didn't (at the time) know that PDFs could "phone home" to report details of the system reading a PDF. A selinux profile denied access to the internet, and it was many months (and 100s if not 1000s of PDFs read) before one attempted network access and denied it. Ubuntu and Redhat (and I'm sure others) have reasonable defaults, so much of the work is already done for you.
And does this happen on android aswell? Because a lot of custom rom/ root users run selinux as permissive for compatibility, so these pdfs would have full network access
