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

Nice one OP. Just had sonar pick up one of these today named like a proper release of a trusted group. Sonarr didn’t move it from qbit but better to not DL it in the first place even though its a linux box
that executes a script on your Windows.
I don’t have a Windows.
Not using Windows helps a ton :)
For those interested, John Hammond did a video a few months ago about .lnk extension (and other 16 hidden extensions on Windows).
He doesn’t go to much or to deep into the subject, but you get a general view how this could be exploitable.
