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.
Dude, you’re so not paranoid. This stuff has happened to me. I had a Wordpress blog that was hacked and the exploit was stored in the DB so even after reloading the OS I still was infected because I hadn’t sanitized my database. Luckily it was just Google search viagra spam, and it was a valuable lesson.
