      nope. my distro was affected but me. i only trust the kernel and its updates but any packages. i always ether review package updates manually or when lazy wait a couple of weeks for the public to maybe report issues, well if its not a security update at least. so i was lucky tbh.

    Well one thing is for sure: With the code being open source it seams many problems are found before any major damage occurs, and also fixed in an "all hands on deck" fashion, unlike having to wait who knows how long for some major tech company to admit they caused it, and then finally get to work on a solution.

      No, I think that's going to far. I think it's more reasonable to say that open source guarantees that problems _can_ be found, while proprietary source makes it all but impossible to find it. In this case, it's really a matter of infiltration and if the Manhattan Project could be infiltrated, you know that Microsoft can be. An important aspect here is that open source guarantees that whistleblowers can't be identified by the code that they have access to. If someone plants a logical bomb in some obscure piece of Windows, then the whistleblower will be instantly identified. But if it happens in Linux, then it might be an external researcher. I think that's very important.

    • @brandishwar

      @@jeschinstad All but impossible? So there are no security bulletins published regarding closed source applications like... ever?
      But overall there is no guarantee that problems can be found whether you're talking about open or closed source. Open source at least allows for anyone to analyze the source code to look for potential issues. But that analysis is only as good as the tools being used or the people reviewing the code. Meaning if there is no static code analysis or code reviews occurring, vulnerabilities will slip by.
      Leading to this question: what other vulnerabilities exist *today* that aren't being detected because the tools aren't good enough, if any are being run at all, code isn't being reviewed or reviewed properly, or the right conditions for exploit have yet to be found? Generally a vulnerability needs to occur to know what code patterns to look for, just as antivirus tools can only detect viruses known to those who prepare the signatures.
      Plus the XZ vulnerability was a process exploit, not a code exploit, that just happened to occur in plain sight because no one was paying attention. The exploit didn't exist in the source code and the person responsible was taking advantage of the fact there was... no actual review happening on what was being checked in. And the downstream distros merely accepted that binary release archive as-is rather than pulling and building the source code - which would've prevented the exploit from going anywhere.
      And the only reason it was caught "quickly" was due to someone running some kind of automated process that relied on XZ behaving a specific way.
      "If someone plants a logical bomb in some obscure piece of Windows, then the whistleblower will be instantly identified. But if it happens in Linux, then it might be an external researcher. I think that's very important."
      Instantly identified? Not even with the best audit tools would that be possible. It would probably still take months to identify an anonymous whistleblower unless the whistleblower was being very sloppy since there are likely a LOT of people at Microsoft with read access to the Windows source code repository.

    Honestly Linus said it the best, it doesn't matter if it is open source or propitiatory software. It can happen to anything. It comes down to having trust and bad actors taking advantage of said trust. I think their should be a few vetted people to look over code before said code can even be implemented, as well as better background checks of contributors.

    99.9% of those who say that ‘open source code can be reviewed by anyone, so it’s more secure’ likely do not have the skills to review any software. The events of XZ demonstrate that there aren’t enough checks on the identity of those contributing to critical parts of GNU Linux. The mistake made by CrowdStrike had disastrous consequences, but it did not open a backdoor that could be exploited by government hackers from the PRC or RF for months or even years.

      2. Just because something is open source doesn't mean it's audited from security prospective, but that it can be examined when needed to, by millions around the world, and some of them can do the job.

    I’ve been in the IT world for over 30 years and windows has been a problem since day one. When I was going to college for engineering in 1990 the entire computer lab was shut down because every single computer had a virus on it. I asked the professor why didn’t someone fix it and he said no one knew how. At that moment, I made it my mission in life. I have been calling it a cyber war since 1998. I bought my first computer in 1997. When the warranty expired in 1999 that computer had to go in a dumpster because it was so riddled with viruses. it was a pain in the ass and I enjoyed hearing the clunk of it hitting the bottom of that dumpster as I tossed it in. I then went to CompUSA And bought an iMac that I used till it self-destructed eight years later. Actually, it didn’t self-destruct but the unit had a CMOS battery that wasn’t replaceable. It simply would not work without that CMOS battery so I just bought two more macs. I got into linux 17 years ago so Linus Torvalds is my hero. I have saved so many PCs from a dumpsters fate by installing linux on them when windows has failed. Crowdstrike should go bankrupt.

      There are many reasons why someone might dislike Windows, but disliking Windows because of "viruses" and using a Mac instead sounds a lot like someone who has bought into apple propaganda, where they lie to their customers and claim that Macs can't get viruses. The simple truth is that viruses are developed for the platform that has the most market share. Windows gets more viruses because it has the largest market share for desktop PCs. If Macs had the largest market share, they would get the most viruses. If Linux had the most market share, then it would get the most viruses. Additionally, this is a very outdated mindset, as viruses that spread easily are far less common today, in part due to how battle-tested windows is now, as well as the fact that it now includes an anti-virus by default. Most bad actors rely on social engineering attacks now.

      The threats that people have to deal with today are nothing like how it was back in the late 90s and early 2000s. The attitude toward security most companies had at the time was very poor. The internet as a whole had yet to transition to using HTTPS everywhere. It has improved quite a bit over time, as more software companies were forced to become more security conscious. This dramatic improvement in security across the board is why the perception that "windows machines are full of viruses" is outdated.
      I don't recall exactly when this happened, but a hacker was charged with the task of obtaining privilege escalation on a Windows machine and on a Mac. They managed to achieve it on both, but it was much easier to do on the Mac. They only needed a single exploit that was easy to find. They needed multiple exploits chained together to do the same on Windows, and it took much longer to find them. This is because the easy exploits have been found and patched already on Windows. Macs don't have that battle-hardening experience that Windows does, simply because not very many hackers targeted it.

If this happened to Linux, it would be limited to specific distros. Even if it was Red Hat, the damage would be less. BSD, even less. It didn't just "happen" to be with Windows.
