Risk of using public trackers

I have sonarr, radarr, gluetun and qbittorrent with overseer allowing my family to request movies and automatically download. I only have public indexers in prowlarr (1337x, kickass torrents, etc.)

This NAS also has a lot of important data like photos and documents.

I am used to vetting my torrents pretty thoroughly before downloading but now it's all automatic.

What level of risk am I running with my data when downloading things in this manner? Is there a chance of malware getting onto my NAS? Ransomware? Is the risk pretty minimal?

a lot of important data

Hope you have a backup, not because of public torrents

I do have a separate backup in a separate building that syncs the most important stuff.

You should use containers (a sandbox for each app you run). That way no malicious app can access your files. The easiest way is using Docker.

You should probably contextualise this and say instead that containers make it harder for the application to affect your environment and files.

It may be possible to break out of a container.

I do use docker, I set up a docker account as well with selected permissions.

The risk of malware is probably low; Plex/Jellyfin shouldn't execute any of it.

on linux/unix you can make partitions files non executable.

Maybe you can mount in fstab a partition with the parameter NOEXEC:

Option 'NOEXEC' flag in the mount command does not allow the execution of executable binaries in the mounted file system1. However, when a script (a text file that begins with she-bang line; i.e., a line that begins with #!) is given to some shells (bash), it will run the executable named on that line (e.g., /usr/bin/perl) and pass the path of the shell script as the first argument. The actual interpreter might not be on that mountpoint.

1 The mount command typically mounts a file system. (Arguably, loop-back or bind mounts may be considered an exception to this generality.) In some cases (e.g., /tmp), this file system will contain only one directory.

This NAS also has a lot of important data like photos and documents.

Those should be backupped! And no, the NAS alone is not a backup, otherwise yo wouldn't be worried.

It is backed up to a another drive that's in a separate building. At least the most important stuff syncs.
