I got hit with a cryptominer on my mac mini the other day. I only noticed because I happened to sitting in the room with it and noticed the fans were working overtime. There was a process, "icloud-services", which was using 100% of the CPU. It's sort of an indictment of Apple that my first inclination was "they've got a bug that's got an infinite loop" instead of "this is malicious software".
After a reboot, I traced it back to a folder in `Library/Application Support` which included a `config.json` that mentioned gulf[.]moneroocean[.]stream, so I knew I'd been popped. Cleanup was easy enough (the files themselves, plus the launch daemon), but it's annoying.
I don't do dev work on that machine (it's really just for plex & stuff) so it must have been some sort of vulnerability in Plex (but not the one described in OP) or macOS itself. Interestingly, I was up to date on my Plex install, but my macOS version was behind what was apparently an important security update related to an RCE (Sequoia 15.8).
> This is terrifying. Who runs things like this open to the outside?
Probably the majority of people with a Plex Pass subscription and most Plex users in general.
As far as I see it, Plex's primary purpose is to allow people who have extensive collections of legally obtained digital media to conveniently access it and share access to their friends and family on pretty much any random device from anywhere in the world.
All my home media devices run Kodi, they run Jellyfin, they run all sorts of fully open stuff, but when I travel Plex wins because it runs on basically anything that can stream video and I can sign in to it in seconds without needing to connect a VPN or enter my password on someone else's device.
Plex in particular is notoriously insecure. It should never be accessible to the open internet unless via a vpn like WireGuard. Just playing with fire otherwise.
I do. I like to stream music from my server onto my phone when I'm out and about. And it's authenticated, so there's nothing terrifying about exposing it (security vulnerabilities aside, but that can happen to any software you expose).
> This is terrifying. Who runs things like this open to the outside?
A budy of mine has got 30 000 movies and series. Better offer than Netflix (what, easily 4x more choice!?). He's got a 42U rack. He gives free access to his server to his friends and family: it's not a business (so what he risks is also very limited in the country he lives in, for he's not making a business out of it).
It's not because you and I don't run Plex servers accessible from the big bad Internet that others don't enjoy doing it.
Now concerning this miner: I've posted about it in the past here on HN but I only run Jellyfin on my LAN and it's only with throwaway containers: I've got a script that sets up movies/series named/organized the way Jellyfin likes it, then that volume is passed read-only to a transient podman container.
When we're done watching the movie, the podman container is deleted. It's over: it doesn't exists anymore.
All that I care about are data: like family pictures and movies (and, say, other movies).
My Jellyfin server is just a temporary "view" on my actual data.
I don't trust it and don't need to trust it: for it's only future after I'm done watching the movie is to be destroyed.
Plex themselves literally recommend it and show a warning icon if it’s not accessible outside your local network. I always thought it was insane. To make matters worse their Synology package doesn’t auto update itself. I would guess there are a ton of vulnerable boxes sitting out there.
What get me the most, are the rabid Plex fanbois swearing that having jellyfin open on the internet is such a baaaad idea and you should spend ~50~ ~100~ 500 bucks for a sub to Plex which totally don't expose the same risk
If you’re exposing anything on Synology to the Internet, you’re already playing with fire. Their packages (like Container Manager) are usually very far behind on security patches.
I think the current version of Docker engine Synology uses was end-of-life 2.5 years ago.
Synology NAS - an ugly doorstop with data loss resulting from its half-baked post-purchase attempts to enforce hardware vendor lock-in. (Was working fine w/ a Western Digital drive, the next day, boom.)

I don't think any more than 5% of Plex users are using it for legally-obtained content.

Many people, as your TV and sometimes friends have to connect to it and you don't want to explain Tailscale to them.
Feeling very validated that I went with Iroh @ https://pixelbrite.site
You largely have to for Plex themselves to middleman access to your media collection.
Essentially every technical person I know.
I do. I like to stream music from my server onto my phone when I'm out and about. And it's authenticated, so there's nothing terrifying about exposing it (security vulnerabilities aside, but that can happen to any software you expose).
I do run it open to the outside through cloudflare tunnels. I don't want to connect my TVs to tailscale every time to play a movie.

Yeah, please avoid Synology, really. If you have it or need it DONT expose it to the internet.

Affects an older version of Plex and was patched in August.
