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.

While others are saying “no one cares about your personal photos” personal info is not the target of backdoor attacks like this. It’s more likely an attempt to get access to lots of processing power for a crypto mine or botnet.

It’s best practice to have the minimum packages required to run whatever service you are running, don’t add other stuff that you won’t be using. Using a distro that is “outdated” like Debian stable can help since the packages have had more time out in the wild to be tested.

I am sure that the xz incident has raised a lot of alarms across many projects.
