From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do we know if there aren't a bunch of more undetected backdoors? (lemdro.id)

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).

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
