How do we know if there aren't a bunch of more undetected backdoors?
I have been thinking about self-hosting my personal photos on my linux server. After the recent backdoor was detected I'm more hesitant to do so especially because i'm no security expert and don't have the time and knowledge to audit my server. All I've done so far is disabling password logins and changing the ssh port. I'm wondering if there are more backdoors and if new ones are made I can't respond in time. Appreciate your thoughts on this for an ordinary user.

We don’t know. However, no one cares about your personal photos ; no one will ever attempt to hack you specifically unless you’re a high value target (in which case, stop hosting your photos anywhere immediately)
The only thing that could get your photos is if an undiscovered backdoor is exploited by someone doing some sort of a mass attack. As far as I know, they’re pretty rare, because people with the means to do them generally have a specific set of people they care about (which you are unlikely to be a part of).
To those assumptions I would say : we don't know. Personal vendettas do exist and we cannot look into the minds of individuals going crazy neither.
That fair enough I guess, really depends on what kinda personal photos you have. I know people are worried about revenge porn, I personally think the only actual remedy is not having any porn of yourself anywhere unless it’s your job 🤷🏻♀️
My brother in Christ, how do you think botnets get built?
They did say specifically. I think bothers are usually automated attacks.
unfortunately, mass attacks happen all the time. if you ever had access to the authentication logs of an SSH server with an unfirewalled port 22 into the internet that has been running for a few months, you would see international IPs starting port scans and brute force attacks. there is always someone out there trying to hack random IPs. it's fucking wild west out there.
Yeah. I'd recommend using ssh keys and disabling password authentication whenever something is exposed to a public network
My ssh auth logs show a lot of login attempts from chinese IPs. That prompted me to install Fail2Ban..
