There are some torrrents showing up with .lnkextension (ex: movie.mp3.lnk, tvshow.mkv.lnk...) and automated software (Sonarr, Radarr, Lidarr, qBittorrent RSS Downloader) could pick those torrents (but not import).

These (fake) torrents include a .lnk file that executes a script on your Windows

HOW TO exclude from download on qBittorrent.

Go to Options -> Downloads
Enable "Exclude file names"
Add patterns:

(one by line)

*.mp4.lnk  
*.mp3.lnk  
*.mkv.lnk
*.torrent.lnk

Or exclude all together: *.lnk

When I read the title, I was thinking of something sophisticated such as hidden executable streams inside the MKV container (IIRC, it's possible to append binary data other than audio, video or subtitles specifically inside a MKV). The ".lnk" trick only works in Windows and, even there, it's easy to prevent: Windows Explorer > Options > Advanced > find and check "Always show extensions for files" (i can't really remember the exact label for this option as I'm not a Windows user, but something like this will be there).

I believe you uncheck "Hide extensions for known file types"

Exactly! Thanks! I couldn't point the exact label, I've been using Linux for years in a daily basis so I forgot most of the Windows shortcuts/options.
