Share 'OMG WTH, PDF?'

Hey Gang,   How much do you know about PDFs? These things are really dangerous. I knew you could hide scripts in them, which is scary enough, but did you know you can hide executables in them? All kinds of weirdness like that.   If you're like me, you get most of your online paper toys in PDF format. Not everyone out there is nice like our community here. Just a heads up to be cautious about PDFs…
