NSA... ...so now these pieces of s**t rather do Win2Go assistance instead of spying, what type of porn we watch?
I must admit i haven't even looked at the pdf, but my general rule of thumb is : NSA bad. It may happen to be a useful guide in our best interests. On the other hand i'm sure even Hitler stopped to pet the odd dog, occasionally make his wife breakfast and was only 99% evil. The eggs were probably undercooked, the dog was stolen and he shot his wife though...
omg I clicked that pdf and it downloaded and printed... ALL ON ITS OWN! ok wasn't that dramatic but wth that was odd as a duck fart
So they finally figured out how to inject a backdoor virus into a PDF. Just kidding, the backdoor is activated immediately when you connect to their server, you don't even need to complete the download to be hacked, they got you with the buffer overlord.
