    blkpws OP ,

    Well, there are virus as any kind of device that runs any logic, the thing here is that is harder to get hacked than with this kind of tools that Windows uses.

    And I mean getting viruses like this:

    So yeah, I don’t need many apps that my Mac has and could be used to hack me with 0 click interaction or with valid Windows certified programs. Still, the “no virus” is not the only reason, updating a Linux system is just a few seconds and your work could have their own repository mirrored and monitored.

    3laws ,

    hack me with 0 click interaction

    That’s very doable on Linux too.

    In other comment you said something along the lines of “just hire an expert”. They charge way more by the hour.

    Maintaining a distro for this very reason will never look ‘cheaper’ for executives. Trust me. They rather pay you to see stuff that has CLEAR and FAST deliverables, that’s what they do what they do, make/save money; take shortcuts.

    blkpws OP ,

    Well, I think they are expensive because they are actually experts, not like random IT hired personal that (in my case) couldn’t even understand how OAuth works.

    Cypher ,

    These sort of vulnerabilities exist on Linux and the software deployed on Linux.

    You are spreading dangerous misinformation with claims that Linux doesn’t have “viruses”.

    blkpws OP ,

    I never said “Linux doesn’t have viruses”.

    Cypher ,

    You linked the screenshot, defended the claim with whataboutism and then dissembled with this.

    Still, the “no virus” is not the only reason

    You could have simply said

    Yes the claim that Linux has “no viruses” is wrong but other points are still valid.

    Though I would seriously question any points made by someone claiming there’s no malicious software targeting Linux.

    blkpws OP ,

    “no virus” is because it’s literal extracted from the text, not my words. I explain then what I understand with saying “no virus”, as any device can have virus, JavaScript runs on Linux, Windows and Apple. It’s common sense. No need explanation.

    Tibert ,

    On Linux -> arstechnica.com/…/password-stealing-linux-malware…

    (not a virus directly from a package manager or distro tho).

    However nothing prevents someone from hosting malware on github, or fake “safe” distros.

    There can also be a slip and people not seeing a project turned into malware.

    blkpws OP , (edited )

    I know about this issue, I have read about it already. No one uses this unless noobs watching YouTube tutorials.

    Cannot be compared to the vulnerabilities I pasted (0 click exploit). Any system can be hacked, Linux is the most used OS and still have fewer viruses issues as others, but it still has as any system has.

    Tibert ,

    Wtf are you talking about. Linux isn’t a distro.

    And the example isn’t a “only noobs use it”.

    It’s an example of an exploit existing since many years. And which could have appeared in a random package, while staying invisible.

    blkpws OP ,

    I said distro instead OS, Linux is the most used OS, many people behind working in secure the Linux environment. The example of this exploit also exists on Mac and Windows for years, and it will always happen.

    An admin user will know what they are doing, and I doubt they will install a package from an external source downloaded randomly on internet, for the non-admin users, without sudo they can’t install/infect that malware on your Linux.

    Cypher ,

    I said distro instead OS, Linux is the most used OS,

    Wrong, Linux totals 3% of the desktop market which is what’s being discussed in the original post.

    many people behind working in secure the Linux environment.

    Many people work on securing Windows so your point is…?

    The example of this exploit also exists on Mac and Windows for years, and it will always happen.

    Whataboutism.

    An admin user will know what they are doing, and I doubt they will install a package from an external source downloaded randomly on internet, for the non-admin users, without sudo they can’t install/infect that malware on your Linux.

    Wrong. This is so wrong. The most common and effective attacks start with phishing people who think they know better. A user downloading a zip or rar file is enough, they don’t need to be an admin or have sudo rights.

    Seriously just stop talking about a topic you have zero knowledge on. I suggest you do a SANS course if you’re actually interested in learning.

    blkpws OP ,

    Wrong, Linux totals 3% of the desktop market which is what’s being discussed in the original post.

    There are more servers than users in this world, even your car runs Linux.

    Cypher ,

    Linux can be used at your workplaces

    Yea given that Linux servers are already commonplace it is clear you were referring to Desktops.

    You’re garbage at this, the worst kind of advocate Linux could have.

    blkpws OP , (edited )

    WTF, you look like having a bad day, because of my lack of English knowledge doesn’t give you freedom to insult me.

    EDIT: I think you are just insulting me, but if Linux is the most used OS means the support should be awesome… worldwide support… while this malware could happen on Linux but also on Apple and of course on Windows, there will be always malware… so at least let’s make one really good as it is right now Linux (with support for old computers, means it’s not forcing users to keep upgrading their hardware), and that’s the reason it is the most used, fits everywhere. Windows only have the monopoly and Apple the “think different” thing (and they give special focus for designers and is Unix, sadly docker is still virtualized).

    Cypher ,

    I look forward to your next unhinged factually incorrect post.

    The linux kernel is not completely secure by default, neither is any specific distribution. No internet connected device could possibly be “set and forget”. Security can not be taken lightly

    blkpws OP ,

    Yup, that is right, any device can be hacked.

    rufus , (edited )

    But it’s kind of true in practical experience. Show me one Linux virus that spread and made its way through some network.

    I can show you more than i have fingers that have been affecting windows.

    SkyeStarfall ,

    When it comes to workplaces, you can expect people to deliberately craft a virus and/or try that break into your system specifically. A lot of the world runs on linux, a lot of hackers try to break in to this world.

    For personal use it may be true enough to be fine in practice, but it’s a very dangerous thing to believe for a professional setting with probably expensive equipment and valuable data.

    rufus , (edited )

    Yeah. I know that. But that’s in theory. And it’s more hacking, not a virus.

    If that’s really true, it’s surely possible to find an example of a virus that did it’s thing (spread) and do a bit of damage somewhere. And not just say hypothetically it’s true.

    I know Linux can be hacked, because I had a webserver hacked. And i see all the logs and the hundreds of login attempts per second and automatic exploits in my logfiles. I have a good idea why most of the Linux boxes get hacked. And all I’ve ever seen were not updated server software resulting in rootkits. 0% is viruses in my experience. Rest is proper issues and maybe the bad guys have been quicker than you. But it’s mostly targeted and rare. And nothing compared to the stuff the windows guys had to deal with during the last year and switch off things until it had been patched properly. We mainly do our updates. And every few years there is a major screwup and you type in a few commands in the terminal to hotfix something. But that’s mainly it. And you can’t make it about any hypothetical issue. While there are supply chain attacks for example, my mom who is using Linux to write her letters and print forms is unlikely to need to learn about that. I told her she doesn’t need antivirus and viruses and trojans are more an academic thing with Linux. She doesn’t need to worry. I also talked about targeted attacks and being a valuable target. But that’s besides the point here. Hence my question and me wanting to stay on point.

    Please just prove me wrong. I’m serious. All I could find are some harmless viruses from 2003 that didn’t even spread enough to have reliable numbers. Ransomware that affected ‘tens of users’. And you got the easy position. I advocate for Linux on the desktop. And it’s impossible to prove something is secure. I always have to go into detail, explain viruses, architecture, package managers etc to get my point across. You got the easy position. All you need is to find one counterexample.

    And arguments are always the same. I do the whole talk and then say you don’t need antivirus because in real-life there are no viruses. And people ask me ‘but what if tomorrow there is one’. And sure. Nobody believes me when I say I’ve had a quick glance into the future with my crystal ball. But what kind of argument is that? What if I’m struck by lightning on the way home tomorrow if I take the bus instead of the car? I guess I’ll just die then. Many people have been under the influence of ‘windows-truths’ for too long and can’t imagine another world. Some people didn’t listen to the first part of my talk. And some just want the computer to work and a simple answer. I get all of that. But it doesn’t make something true or false.

    [Edit: Sorry, had to post this again. I deleted the previous comment by accident instead of editing it what I was trying to do… And Lemmy doesn’t seem to federate deletions that quickly. I’m still learning things here…]

    Nolegjoe ,

    There’s an entire list of them here

    en.m.wikipedia.org/wiki/Linux_malware

    rufus , (edited )

    I’ve read that list. There’s not a single name that rings a bell. Which one of those had any consequences in real life and is more than an academic study?

    (And besides that: Sure. It’s funny to make every program output your name. But it’s pretty harmless and not on the same level with viruses that do proper damage to a computer infrastructure. I wouldn’t lump all that together. That’s not right, either. And misleading.)

    Cypher ,

    Your ignorance on the topic does not make the claim that there are “No viruses” on Linux any less absurd and inaccurate.

    You have multiple cyber security experts in this thread telling you that you’re wrong. It is not on us to disprove the claim, or to educate you.

    rufus , (edited )

    I don’t understand. You made the claim Linux viruses exist. Why is it now my job to disprove their existence?

    It’s like with God, Vishnu, Thor, … You claim existence, you show me.

    If there are that many experts around. Why can’t they do more than link a Wikipedia article that doesn’t (yet) contain the information I’ve specifically asked for? Shouldn’t they know at least something themselves? At least know 1 name from the worst offender? Why does the other half of experts not know the distinction between virus and other forms of malware? And that it makes a difference here?

    I see that people disagree with me. But I seriously doubt that there is a single expert around.

    I swear I’m not trolling. If you’re an expert, just give me the name. I’ll even try to look it up myself and if it’s a virus and spread across a few hundred computers around the world and maybe more than 2 or 3 companies and I can find maybe a newspaper article that says it did some harm, I promise I’ll accept that and change my opinion. At least tell me you’ve learned in uni that Linux viruses definitely exist in the wild, but no studies have been done because of X or Y. And we have no numbers. I would think that’s very curious because there are so many linux servers out there, but I’d at least have something to work with. (And don’t take things out of context.)

    Cypher ,

    The original post made the claim, I merely stated fact that Linux can be vulnerable to viruses like any other OS.

    Want a straight forward answer?

    linux.com/…/myth-busting-linux-immune-viruses/

    A virus is a specific type of malware but for the general public is broadly synonymous with malware. Ask the average user, and the commenter in the OP screenshot, what the difference is without looking it up and they can’t tell you.

    A virus doesn’t need to be spread broadly for it to be concerning, impactful or dangerous. Often these attacks are very carefully targeted at the victims.

    A vulnerability is generally exploited by a virus to inject code by either modifying memory or files the target program relies on. One such vulnerability was

    arstechnica.com/…/linux-has-been-bitten-by-its-mo…

    With this vulnerability it was possible to modify any file on a Linux device, meaning viruses would be simple to implement and deploy. Many android devices are still vulnerable.

    To think that all possible vulnerabilities have been fixed, or are known to linux developers, would be extremely naive.

    Furthermore a virus is often targeting a specific application and while OS level controls restrict the avenues of attack it doesn’t prevent flaws being introduced by developers.

    You’ve already been given a list of viruses for Linux, if you’re genuinely so concerned with defining them by impact you can look them up. You have the information needed to do this yourself, and it is not my responsibility to educate you, though I do seek to counter misinformation where possible.

    rufus , (edited )

    Well, the first article pretty much says what I’m saying. In theory there can be viruses. In the real world they have pretty much no effect. They are more a curiosity than something that really exists and has had consequences. It even says you’re installing antivirus because of the windows clients, not because there were linux viruses.

    The second article also is about a security vulnerability and talking about potential consequences. Not a virus that uses this as means to infect people. Not actual consequences.

    We’re going in circles. I’m sorry.

    And a virus and a vulnerability in some software (or kernel) that can you get hacked are two entirely different things:

    • They affect different parts of your infrastructure. It is unlikely that someone executes random binaries on your webserver. It is very likely that someone wants to listen to Spotify while editing 150 excel spreadsheeds. So it’s likely your employers execute stuff on their workstations. Also you wouldn’t install a browser in an AWS cloud instance to look at lewd websites. You’re going to use Chrome on your workstation. Viruses affect other and distinct parts of your infrastructure.
    • You protect for them by different means. Antivirus helps with viruses. For targeted attacks on your webserver, you have firewalls, filter requests, keep your software updated. And don’t do silly stuff. I’ll admit rootkit detection is kind of similar to antivirus. There is some overlap, for example you should also keep Chrome updated on your employers workstation. But updates won’t help you against a virus editing a file on the network share to replicate. You do vastly different things to protect against the different security threats that your company faces.
    • All the threats have different consequences. Some things just try to wreack havock in your company. Some things you’ll barely notice but hackers are stealing information. Some things try to extort you. Either by blackmailing you to pay to get your data back, or so it doesn’t get leaked. The next few workdays after that happened will be very different, depending on which of those possibilities happened.

    So while talking about cybersecurity. Why would I lump all that together and strip the words of their meaning? And in this case on top: One thing is something that actually happened. The other things are just words about something hypethetical. I’m aware you have to protect against potential threats. Nonetheless both things are something different.

    Regarding your advice: Yes. I’ve looked it up. I found no viruses that had any significant real-world impact. Hence me insisting on it. I said in my first comment I want to see impact. Not an academic study. Because context matters. We’re talking about someone advertising Linux to an undetermined group of people. These people are concerned with implications for them. If they need to worry. Not if in theory anything can happen. That doesn’t help you choose between two options. And we’re talking about ‘simple truths’. They’re kinda always false. But people want to hear them. They want it condensed into one sentence. Because they own a company that manufactures car tires and they don’t want to get a 20 minute lecture about computer attack vectors. They want to hear if they need to worry about their Linux server. Is it safe or not, do I need to pay someone to install Sophos? And be done with it.

    You’re twisting my words so they lose meaning. And change the context. And then posting articles about something related but not the thing.

    Cypher ,

    I found no viruses that had any significant real-world impact.

    So you found viruses, which debunks the claim in the OP, yet you remain skeptical they exist.

    We’re done here.

    rufus , (edited )

    Please read my first few comments. I’ve talked about it and that’s not what I said. I have found no viruses conforming to what I’ve clarified in my very first comment. I’ve also explained why it’s important to differentiate. I have found things alike. But never the thing. If you twist my words enough and change the context, it would almost seem like I’m contradicting myself, yes. But you’re the one twisting things around until you’re right.

    And why are you just now talking about that? Nearly every single comment of me starts right with a sentence that clarifies what I mean?

    Cypher , (edited )

    I have found no viruses conforming to what I’ve clarified in my very first comment

    Frankly I don’t care about whatever “metrics” you have made up to justify your ignorance.

    Actually I have a better idea, please contact Linus Torvalds on Mastodon with your opinion that there aren’t any viruses on Linux.

    I will happily eat some popcorn while reading your eviceration.

    rufus , (edited )

    For the record: I’m not the one changing the meaning of the word. I use it like in the definition. You’re the one extending the meaning arbitrarily.

    I think I’ll just wait and see if some expert comes along and gives me my single example. If that doesn’t happen I’m going to stick to my opinion: They exist in theory, but not in practice. And vulnerabilities and rootkits exist, but a vulnerability isn’t automatically called a virus because those are different things.

    www.debian.org/doc/manuals/…/ch08s08.en.html

    To end with some more friendly words: I’m pretty sure some people are confusing the words ‘malware’ and ‘virus’. Malware is the umbrella term. I’ve already admitted there is malware. For example the Mirai worm i think had affected hundreds of thousands of IoT devices (speaking of fire and forget embedded linux). And I’ve seen wordpress plugins with vulnerabilities and actual rootkits on webservers myself, as I told earlier. But I’ve also said in this context the distinction matters.

    Yeah for a “red hat certified engineer” that seems like a weird hyperbole to die on
