LINUX vs VIRUSES | HOW SAFE IS LINUX?!? | 4K

LINUX vs VIRUSES | HOW SAFE IS LINUX?!? | 4K // Linux is a great operating system and many people have heard about its famous immunity to any kind of viruses. How TRUE is that? Well today, we will try to find out and sum it all up!

Under the definition of "virus", we usually mean any kind of potentially harmful software such as "malware", "adware", "spyware" etc. Nobody likes this stuff and it causes a lot of issues in the computer world.

There are a few most common sources of this potentially harmful software:

- emails;
- URLs or websites;
- software

If you are being cautious, you can avoid 99% of all harmful software. And unlike Windows, where you need to get an antivirus program to protect your computer from viruses, Linux does it on its own and today we will find out how it does it.

thx for such helpful content. switched to linux mint cinnamon edition 6-7 month ago and it never disappointed me. haven't faced any single issue. my laptop working a bit better after i updated it to linux mint cinnamon 21 from linux mint cinnamon 20.3. fortunately, i haven't faced any single error or viruses where windows can automatically fail or crash without doing anything. now i understood what it feels to have an OS that's 100% peaceful. although linux is also vulnerable but not much as other OS. still at least i am not facing errors, corruptions and failures daily in linux mint as it used to occur everyday in windows

"You want antivirus so other windows guys dont get infected". I missed the part where that's my problem.

What about Linux, Firewall and Targeted Hacker attacks? Thanks.

Thank you so much for this video I've just installed Linux on my HP laptop that can't run windows 11.

I'm probably gonna get a boatload of disagreement and hate for this these words.... but If people would use a standard account instead of using an administrator account all the damn time, a huge percentage of the Linux "safety" is exists on windows. And it's still possible for malware (not viruses) to do damage on Linux without the sudo system. It's called caching and disguise, and disguising is exactly the same as on windows, people.

A very possible form of Linux might malware could be this: in Linux, there is no executable file format or anything to control which files are executable. This is bad in my opinion, because if executables are not instantly identifiable, you might have 5-10, maybe more files that are have no extension, but are secretly executable. Now Linux attempt to executable anything as long as the file has certain bytes in the beginning (not an ELF header, you don't even have to use the elf loader, it's that open). You can execute anything as long as there's software to support your cause. You can always check with the terminal or right clicking, but it's not convenient, and people naturally gravitate towards convenience, even the ones who might say that they "like it the hard way, " and sometimes you might be in a hurry, just careless, who knows, anything is possible here. And now, you installed the program, and you got a bunch of files and folders, and say you execute the file you think is actually there, and it's disguised and contains code to execute a hidden script or executable that you had no idea was executable because... no extensions. Now the executable can run scripts and other program's in all that it wants.

You can also preserve a file's data in memory while the process is terminated and get the data back in another process. It's called shared memory, and malware can infect already running programs, or start its own program that looks like a daemon or something, but it's actually a placeholder for anything the malware needs to "preserve" in case the malware's process is terminated. If sufficient IPC is not possible at the time, it can save it's data in configuration files as disguise the data as normal system configurations.

And yes, Linux is a monolithic operating system kernel, and this can lead to more possibilities in the future.

Also, a program can cache data in memory and then once the disguised program is sudo'd, it'll have all the permissions to attack. Once Linux becomes a big enough target for it to matter even bothering attacking, attacks will come. 'sudo' _can_ be bypassed with extremely clever programming on the attacker's part. I really wish file extensions were mandatory for the operating system kernel to actually execute any code. I see so many possibilities with people using disguised files in the future.

Great review for understanding, thank you very much!

nice channel keep upload video like this

What if I run malware on wine? Is this going to damage the system?

[allanpatterson]

If you want to wipe a hard out that ran microsoft format it in Linux the format it back in microsoft then pick some other odd sytem to format in . Long format that takes time not just disable the labels.

[MrMac]

I have been running Linux for 11 years and Never Never had any

[avikghosh]

what if the linux machine has wine installed?

[rtroadtimelapse]

Linux is a great Operating System! Please make a review about Qubes OS! 👍

[allanpatterson]

Measures and Counter measures I doubt anything is invulnerable.

[abdullahal-shimri]

Wtf is a Linux virus lol. 10-year Linux user and never had a virus.

[scottkeiser]

There's just not as many users and most Linux users are somewhat smarter than windows users being that we got to use code in the terminal just to do the simplest things and not only that there's so many versions so making a code that works on all versions is harder so that being said why spend 100 hours to break into a computer that only maybe 10 percent of people use when they can hack maybe 90% of computers if they use windows and Linux users are more likely to be able to remove the virus on there own

[narahinampas]

you don't need anti-virus if you don't have WINE installed in your Linux machine

[sabestek]

not really .. at least not anymore that is as more people run Linux becomes popular the more viruses will be written for the OS. BSD offerings i.e. OpenBSD, FreeBSD is more secure than Linux however. Either way still more secure than inferior windows without a doubt.
I use FreeBSD w/ZFS. A True UNIX System ! peace✌
