Hi, there!
Newbie question here: basically, the title. Perhaps what I’m asking is pretty obvious, but I’d like to double-check with the community on this.
I use Discover on my Debian KDE Plasma set-up, with Flatpaks enabled (but not Snaps). Sometimes, I come across apps (I did just yesterday, searching for translation apps to replace DeepL), that have according to its page, an unknown author and, sometimes, even an unkown licence, but which do require access permission to the whole system (this latter requirement applying specifically to Deb packages, from what I’ve seen).
Under these circumstances, is it safe to assume that such apps will still be safe because of the fact that they appear listed on Discover (in other words, is Discover a guarantee of safety for the apps it shows, as in, some type of checked or proved content), or should I still be wary of potentially malicious software included on it?
Thank you very much in advance :)
Debian repos are basically guaranteed safe: https://programming.dev/comment/22863237
Flathub is much, much safer than say, the google play store, but it ultimately does follow a model of app developers submitting packages which get reviewed and approved. In theory, someone could sneak malware past that, although there haven’t been any incidents (perhaps flathub’s review is very effective?). But the snap store, which follows a similar model has had malware. But canonical hasn’t been the best steward of that one.
In addition to this, not all stuff on flathub is open source, which is definitely concerning.
Thankfully, flatpak has a built in sandboxing system, which lets you limit what the appps have access to. KDE has a UI for it, and there is also the GUI app flatseal.
