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
Are you executing the files you download?
“There is no such thing as a dangerous file, only bad operating systems.”
can i become part of your family too?
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.
Actually no. I do not use root account. I have separated users for containers :P
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.
