Opening a malicious PDF can launch malware that will start up whatever process the hacker has in mind. That is, by clicking on and opening a PDF or other file, a user also unknowingly starts up a predator program.

If you open up the Cross-Reference Viewer or the Object Viewer you will see there is a new 'Decode Stream' button. If you select a PDF stream object and hit this button a new window will popup with the decoded contents of the PDF stream. This will then allow you to view the commands inside a PDF file.

A page in a PDF document has one or more content stream parts that together contain all the PDF page description commands for the page. So content streams are essentially the contents of the pages - the text and any line drawings.

PDFs make engagement difficult to track However, the biggest issue with this file type is that engagement and performance can't be tracked. You can probably see how many times a file was downloaded, but data like resharing, time spent reading and links clicked are wiped away.

Luckily, many PDF readers, like Adobe Acrobat, have free versions, so you don't have to pay to read PDFs on your computer. Find the PDF you want to open in your Files and double click to open. Select Adobe Acrobat (or whichever reader you downloaded) from the list of available options.
