Why does your admin account look like a scrotum?
Yours doesn’t?
... and yet some of the same people will readily copy-paste random shell scripts into their terminal without fully understanding them.
Let me open up my Linux bible and see if its malicious
But a forum post said it would fix my issue.
Even if you understand the commands, you need to trust the website because a malicious site can use JavaScript to copy something completely different into your clipboard, with a newline character at the end to automatically execute when pasted. (Is the newline exploit fixed in all shells? It used to fail in zsh but work in many others...)
One can also paste into a text editor to verify before pasting into terminal, but what noob is going to know or bother to?
Remember that time, when it was possible for about 6 years to hack into any Linux system (without drive encryption) which had GRUB by pressing backspace exactly 28 times? Yeah, good old times.

If the adversary has physical access you are generally pwned either way
Yeah that is not really an "OMG" vulnerability as I can also get into that machine by booting it with a USB drive, or plugging it's drove into my own machine.
Breh. What? I feel naked right now.
Better replace your keyboard everytime you leave it unattended, someone could put a keylogger in it. Don't forget to check for hidden pinhole cameras around that capture you inputting your passwords. Etc, etc. Those even work against an encrypted drive...
To be fair I rotate hardware and DE so often my drives are wiped nearly monthly. But Jesus this is egregious.
grub's always been a hack. The first stage in 512 byte boot sector chainloads the second stage in the space between boot sector and the first sectors of first partition. Second stage chainloads the kernel. (This is my primitive gist.)
grub was never made for security, it just exists in a place where one would think security would be priority... but again, physical access = pwned, etc.
Not quite the same, but funny: I recently unlocked an HDD from a car head unit to prove to a friend that it was only storing music ripped from its CD drive (and the associated minimal CD title database)... Toshiba master HDD password is 32 spaces. 😅
Oh shit hahaha that's straight up disrespectful. Well yea I guess that makes sense but I just never thought to deep about it.
That's hyperbole. Such a system can be "hacked" by simply plugging in a usb-stick and booting from that instead, or dozens of other ways.
The only reason to use GRUB authentication I can think of would be in something like a kiosk.
A friend of mine once downloaded something malicious to his Linux machine and wasn't worried about it. Then some time later, while browsing his files from a Windows machine, saw it and was like, "hey, what's this?" Oops.
He's a tech savvy guy, so I'm guessing the fact he had downloaded it himself really let his guard down.
That's why you don't store your stool samples in the same fridge as your chocolate pudding. Malware goes into the vault.
Wine automatically running:
Modern viruses check the os before deciding which type of file to send your way.
This is why you use a user agent switcher to lie about being windows. It's a form of anti malware!
Except websites can tell what base OS you run using browser fingerprinting. It os impossible to lie aboit your OS because of the differences in platforms.
You can lie about your fingerprint very much in fact it is the default on librewolf

Generally browser fingerprinting is used to identify individual browser sessions across IP addresses. This mostly takes into account reported features and capabilities of the browser and OS to the website. Fingerprinting isn't looking for specific info your browser reports, it's taking it all and hashing it to get a unique id specific to the browser. Because it's hashed, it can't be reversed to identify the OS from the hash.
Sure a malicious website could Ignore the user agent and probe for some hardware capabilities that are specific to Linux, but that would be a lot of effort to probe various things which are set differently across all different browsers. I can't speak for bad actors, but I wouldn't spend the effort to check if the user agent is spoofed, if 95% of the time it's accurate to get the OS type.
It is trivial to identify OS platform because browser work differently on each platform. Wjat Librewolf does with useragent on Linux actually is makes users stand out more because it isn't what privacy.resistFingerprinting (RFP) reports on normally.
Hackers (like the comment scenario i was responding to) are substantially more likely to employ platform fingerprint than trust a fale useragent. And loads general websites employ fingerprinting, meaning deviation from default RFP behaviour makes you stand out (more than you already do by using RFP since it is a small pool already).
Agreed, I'm not saying it's impossible to detect the OS, but it's even more trivial for an adversary to regex the User Agent and serve the malware for that OS. The average user doesn't even know what a User Agent is, and that's who the drive by malware websites are counting on to infect because they're easy targets.
Just like a real fingerprint, that will only identify the fingerprint to a person, not tell you that the fingerprint is from someone who is European. Fingerprints are used to track you across different websites, and build a profile of you for advertising.

Pick the least POSIX shell, or roll your own!
Rename all the coreutils. Confuse yourself and the hackers!
Do you have any data to back up that claim? I don't think that's true at all, it would be very rare.
Do you have any data to back up that claim?
None whatsoever.
I don’t think that’s true at all, it would be very rare.
Suspicious words. You have one, don't you? Don't worry, I won't tell.
Why suspicious? I have genuinely never read a news story about a virus sending different versions of itself to different OSs. I'm sure it happens, but it doesn't seem common at all, and you are claiming it very matter-of-factly so I am interested to know more.

This is were WINE comes handy /s
Virus running in wine: "WTF is this place. It's familiar, but it's all wrong!"
WannaCry: Platinium
https://appdb.winehq.org/objectManager.php?sClass=application&iId=18249
I'm not clicking that link
Why? You don't wanna know how well WannaCry runs via Wine? The site is perfectly harmless.
It's just an entry in Wine's AppDB, where they keep track of how well apps run on wine. Like ProtonDB, but for general applications.
Whole bunch of people trying to get me to click this sus link...
You're never gonna do it.
I cast Millennial Paranoia, BOOMERS.

Jesus, the downvotes! Well, I thought it was funny! 😂
If you comment in Programmer Humor, you have to accept that a lot of the community has problems detecting irony.
