A game I downloaded after following the Megathread activated Windows Defender. Most searches in the reddit showed that it was a False Positive but I checked in Virus Total just in case and found this. The website was RePack-Games (I read the note but I didn't find the game on the Goat sites), the game was Dynasty Warriors 8. I'd like to ask what my next course of action is here. The game also wouldn't load after the cutscene when u select a character.
The spec is fairly complex. Someone ported Doom to PDF, for what it's worth.
That doesn't make PDF an inherently dangerous filetype, but I'd say it increases the likelihood of bugs/zero days within the PDF viewer.
Every file can have zero days targeting a specific application though. Sure, PDF is a bit worse than other formats in that regard but I'd say the likelihood of a zero day PDF is approximately the same as a zero day MP4 for your video player.
