I appreciate your effort and really enjoy the discussion. Most of your suggestions are probably a good idea for the future, but they are not really a solution for a potentially infected system right now.

You can pull out the big gun as well and purge all AUR packages entirely or even reinstall your system, but their might be an easier solution.

What do you think this does, in bash:

:(){:&:;};:

Without looking it up, I wouldn’t have had a clue. It looks somewhat purposefully obfuscated but used in the right context, I am not sure I would have picked up on it. Maybe you are right and I should reconsider my approach.

I have no idea about the stance of CachyOS on AUR packages.

I totally agree with you, establishing trust is not an easy problem. I don’t expect the average joe to understand shell scripts. I would put myself in that categorie as well. This one however was simple enough that it seemed okay to me. If I don’t understand what’s going on in a script I am really careful and try to avoid it, if possible. I still wouldn’t consider them universally bad. For some things it is even the recommended install option. I vaguely remember some things in the Raspberry Pi universe ( IIRC this was even the case for Docker in the past).

There are multiple factors which can lead to trust. Maybe you know the CachyOS forum and how well it is maintained. How old is the account etc… But as you said, there are always risks. The account could be compromized as well. But most of that isn’t specific to shell scripts or Linux in general. You shouldn’t install an application from some shady website in Windows either.

What is your recommended way to deal with the current situation?

I don’t use CachyOS nor do I know anything about their team and I haven’t used the script either. My point was just that I would trust OS maintainers more than some random guy on the internet.

I have checked again and it seems the script I was referring to was actually from a mod on their community forum. Not sure if this is a maintainer as well or not.

My point still stands, if you trust the source and checked the code that nothing shady is going on, it is perfectly fine to run a script. Even if it is just an additional check after you cleaned it manually. Maybe you have missed something.

I haven’t checked the scripts from OP, but i think there is a script that is provided by the CachyOS team that basically just contains a list of compromised packages and compares that to your pacman -Qm output. If it finds a match, it tells you that the compromized package X is on your system. That seems pretty reasonable.

I get your point and as always, you should check the source of the script as well as the code inside of it. Never installing anything outside of official OS repositories is probably not an option for most people. There are always pros and cons. Like in my example maybe some OS maintainers know more about the affected packages than I do with a quick search. On the other hand, the script might be outdated because the number of packages changed a lot over the last few days.

Nice, seems like it was a good decisions. Do you miss anything from the Xilinx world?

I am very much pro open-source, but these are highly specialized tools for a very niche market so it is atleast somewhat understandable. Unfortunately we are not blessed with open source toolchains like software developers even though there are some steps in that direction. Because it is such a niche market, it is like the software space from 20-30 years ago. Proprietary tools and compilers were pretty common back then and for some microcontroller architectures outside of ARM and RISCV they still are I think.

What do you mean by this kind of shit? I am in the FPGA space for quite some time now but I don’t think something like this happened before. When did you leave and what are you using now? I agree with you on the support. If there isn’t an (unpaid) member in the community forum or on some other platform you are pretty much fucked. I never used another vendor, so I can’t say if it is different there though.

Purely from reading about the different tools Restic is also my favourite at the moment. I mainly want to use it so my client devices can do backups on my NAS and maybe at some later stage backup my NAS to a NAS at a family members home just like you do.

Good point. I was going to set 1-2 of them up and find out what suits my needs.

Started my self-hosting journey a couple of year ago with a Raspberry Pi, OpenMediaVault and a couple of Docker containers. This week i finally managed to move my Adguard Home container and my DNS setup over to my NAS, which was the final thing that kept the Pi running. I also synched all the data to the NAS.

The next step I am trying to figure out is a decent backup setup. Read about Borg, Restic and Kopia, but haven’t decided on one of them yet. What are you guys using?
