I fucking hate the mentality that Linux is somehow completely safe.
Just because it isn't attacked as much because of the low adoption rate among users, doesn't mean it has no vulnerabilities.
With SteamOS and ChromeOS now having millions of users, Linux attacks will become more commonplace.
IIRC ChromeOS is either built on or can be configured to run applications like a Linux distro?
Yes, so Linux better be ready, because those attacks will increase.
And sentiments like the one from OP don't help one bit.
Malware for desktop users is the low hanging fruit with little rewards. You just hear about it because it's so rediculous easy.
The real money is on servers, so that's were real money/work is invested to develop malware for much higher gains. How successful are they again?
I think you're right. A single desktop, unless it is either someone in a position of power or access to trade secret files, is not a time effective attack vector.
A server on the other hand can access all of that stuff across an entire organization.
Not just that but whenever you hear that company xyz was hacked and their data leaked, what do you think was powering their servers? Most likely Linux. Sure, they usually have more things exposed to the internet, but users install way more apps so the attack surface is vastly bigger in home computers running Linux than servers.
A lot of critical vulns are exploiting cross platform applications, log4j...
Wine appears in the output of
ps aux.Nervous not-an-emulator noises.
Have people tried running malware in Wine? Would be interesting to see how 'well' the malware would work.
The cruder the malware, the better your chances of running successfully in Wine.
Because throwing together some simple executable using inbuild windows functions is much easier than programming something well-build and hidden based on deeper system layers. So your random "I just encrypted all your files because you clicked this .exe, now send me bitcoin to get it back"-bullshit might work well on wine (which is why wine should be run as it's own user with no priviledges to access anything but your Windows programs).

Lol as if Linux is free of malware.
It was, 25 years ago. Same as Windows' security was absent at that time.
But people never update their prejudices, so all the jokes are from the last millenium.
If you want an OS that is really malware-free, you need to run temple os.
It isn't, but you're unlikely to encounter Linux specific malware.
I've been using Linux for almost 20 years, and AFAIK in all that time I've never encountered a Linux virus. OTOH when I run Windows, I hit a virus within the first six months.
Sounds like you have bad habits, I've had windows for years and no problems. Just scan with Defender after a download, occasional Malwarebytes scans to make sure, and you're pretty safe.
Most viruses are written for windows but that doesn't mean you're just instantly safe. You can bet as Linux grows they'll see far more.
— When the Indian Amazon support guy sees you're a junior on your first week and tells you to execute a script to install a software for a video call with him. And you do, but it needs sudo access, so you give it...
— You have sudo power here
Sadly, true story. I never told anyone. My neurons clicked a day after that and I removed everything from the computer. It was too late, they hacked some things but IT just laughed and recovered some backups. They never knew I was the virus all along.
Good times.
Security through obscurity is not security
That's why I use NixOS. Double the obscurity, double the security!
Say that too loudly, and you might upset the apple crowd lol
True story, Linux sees MIME types, so if Hot.Chick.Blows.Brother.mp4 is a virus, it shows up with a Windows (MZ) binary icon, not a media icon 😉... unlike Windows which only recognizes extensions 😒.
Microsoft, in their infinite wisdom, also decided that file extensions should be hidden by default. So you won't even see that you downloaded TaylorSwift_1989_TaylorsVersion.exe instead of TaylorSwift_1989_TaylorsVersion.mp3 unless you changed that setting ahead of time.
Or worse, Numb_LinkinPark.mp3.exe just shows up as Numb_LinkinPark.mp3, making it look like it's DEFINITELY a legit MP3!
It's even worse, since exe files can have custom icons, the malware will have a mp3 player icon in their exe file, making it totes confusing.
And this only gets worse, since audio file tags (and I believe video files as well 🤔) include album art nowadays, so it has an icon that is the album art... exe's also have custom icons, so 🤷...
That's not a Linux thing. It's just whatever desktop shell you chose to use and various shells behave in various ways. The reason this might be safer in most Linux distros is that you're discouraged from executing things under a privileged user which means that malware can't make significant changest to your system easily. If you do the same in windows, you'd be just as safe.
Not exactly... I mean, yes, you're right about the privileges thing, but Windows has a lot more security holes than Linux (or any POSIX based OS for that matter). The root of the problem, as always is the distant Windows relative, DOS... no user space notion whatsoever... and Windows NT has dragged these issues for decades now, all because MS made (bought) DOS and distributed it.
My memory is fuzzy and I don't know the correct words to research it, but I am pretty sure that depends on the DE.
Either KDE Plasma (dolphin) or GNOME (nautilus) uses the extension iirc. Maybe that changed though.Have no idea, haven't changed a DE in over 6 or 7 years, I use xfce.
You guys are quick to forget that Wine (Wine Is Not an Emulator) is, in fact, not an emulator. Most windows ransomware will successfully encrypt your files if ran with wine.
That is why I always try to avoid installing Wine natively
How else do you install WINE? Is it possible to sandbox WINE apps?
If you're feeling even more paranoid, go with something even more obscure like Plan 9 from Bell Labs. It's Unix-like but differs so much from it that a Unix or Linux type malware would do nothing to it.
but then the little Wine window appears
the wine prefix is being updated, please wait...
False sense of security. You accidentally downloaded a virus that doesn't work on your system... What kind of habits and hygiene are you rolling with on a day to day basis?
It's your grandma, you gave her ubuntu and everything has been good for a while.
If you use Linux because of this you are just a kid following the hype
What exactly would be a non mainstream OS?
z/OS?
CP/M?
Downloading a virus has as much effect on Windows as it does on Linux and any other operating system: None.
Unless it exploits a security vulnerability with something that automatically touches the file. Like a virus scanner.
or a thumbnail generator
Next you're going to say https://www.cisecurity.org/benchmark/red_hat_linux exists for fearmongering.
WINE
Also...Get a whitelisting antivirus on windows.
so, I had a pendrive that a friend borrowed once. later on another friend used it and said it had virus. I simply couldn't know since I was on GNU/Linux.
though later on I cleaned it with dd.
I work service desk. This right here is the reason I tell Mac users they need to keep the AV on.
I think the majority of exploits in metasploit are for Linux, but could be wrong.
What if the virus is written in javascript
then i will contact the malware developers and rewrite it in rust /s
Then I'll go back in time and install NoScript on my browser
Malware for Linux is a thing. I see it every day.
You accidentally click it and wine starts launching:
Way back in 2003, I had a school project partner over to do some work on a project. They had a floppy that was infected with some malicious stuff and had planned to utterly trash my computer with it. I only found out at a later date because some guys were asking me questions about my computer, and someone spilled the beans whenever they realised that my computer wasn't infected and was indeed still functioning completely fine....
Wine
still has power if you email or share it to someone else after you downloaded it
