yep, that was an infected PDF all right, and a whole lot more.
Here's the reply I just got from SANS:

Thanks for writing in!

VirusTotal flags that trojan .exe as a downloader, so I'll wager the victims of this have more than just an infected PDF and a trojan to worry about.

Can't say this enough: run at least a couple of good virus scanners, such as MalwareBytes Anti-Malware.

Nice catch, zanzizzi.
