I am still not sure about it, but if a compromised comment reached your instance (through federation) and users in your instances viewed that comment, they have been hacked too.
MAYBE you are safe If your instance has no custom emojis enabled.
For sure it is sufficient for a quick fix. But a Lemmy post can be posted not only on Lemmy but on other front ends (like kbin, mastodon, and many others) and they can suffer from a similar attack due to the backend storing and forwarding the bad content. So, it should not be stored as it is in the backend
Good question. I have the same problem with flatpak (I have both 525 and 515 version installed at the moment) but I use the deb version of steam, not the flatpak one. I should try to remove them.
BUT, if I recall correctly, I still have something relayed to Nvidia 515 installed via apt (for example, when the kernel updates, I see that apt compiles the modules related to 515 together with the ones for 525).
Yep I think it's time to stop using Ubuntu because of snap and how they are forcing it. Nowadays the are many distros suitable as daily driver. If you don't want something too much different I suggest Pop OS (I use it on all my machines). In those years it has proven to be very stable, maintainers behind it are very good in what they do and it's pretty much updated (for example new kernels and new Nvidia GPU drivers are tested by the maintainers before they offer the update to you, so when you update you are 90% sure that everything will be ok)
I've wireguard managed through the network manager (and a home extension consequently). I don't remember how I did it but I remember it was pretty straightforward to do
How are you preventing it to happen again until a patch is released from devs?
