Hey all, recently I was doing some work on the machine where I host my plex and audiobookshelf servers and I noticed that there were 3 new devices listed in the disk manager.

All 3 of the new devices have a description along the lines of "78MB Loop Device" and lists a backing file at location /var/lib/snapd/snaps/snapd_22291.snap (not exactly but they're all similar to this). They show as unmounted and I'm not really sure what this is.

Additionally when I try to use libation to pull my latest audible books down it says it can't read my local file location folder.

I recently saw the post about the plex vulnerability (which is part of why i was doing work on it, to make sure that my auto update was working) when I noticed this and it got me worried.

Are these new devices that showed up indicative that a malicious user has accessed my system through the internet and has setup a crypto miner to run in the background on my server or is it more likely that a disk is failing and this is the first sign?

Also before anyone feels the need to say it, I know that plex is not ideal and jellyfin is better, but I have remote users that I cannot talk through troubleshooting to get jellyfin when I can tell them to just install plex on their end.

Any help would be greatly appreciated

They don't go away on their own, every installed snap is mounted as its own loop device and snapd keeps an older revision or two so it can roll back, so the number moves around after updates. snap list --all shows which snaps they are, if one says disabled that's the old revision and you can remove it with sudo snap remove <name> --revision=<rev>. about libation, if it's installed as a snap itself that could be the actual problem, snaps are confined and can't read folders outside your home or on other drives unless you connect the removable-media interface, so I'd check that before worrying about the loop devices.

Awesome! That was going to be the next thing I looked up was how to do the snap list. It shouldn't be impacting my libation as that is running in a docker instance managed by portainer. Though now that I think back I had initially installed libation using snap, but couldn't get it to work, so perhaps I have both instances running and am trying to use the snap one on accident when I need to be opening the docker instance.

yeah that sounds like exactly it, a snap that never worked still sitting there. "snap list" will show it, then sudo snap remove <name> and you're left with only the docker one, so whatever you open is the right one
