Without context, I would suggest Transmission for troubleshooting. Qbittorrent is bloating and weird on Windows.
The torrents should be hashed, but that wouldn’t stop someone from making a bad torrent or seeding one.
If someone made a file intentionally collided it would probably cause issues. These aren’t collision issues, but bad chunks of data.

At a peek, it seems that this attack only causes delays in downloads. It’s more possible that there are commonly shared files with similar issues.
I can’t deliver this if I can’t envision how to get there.
