There is such a question on Zhihu. I feel that the questioner does not know much about the Linux system, so I came to answer a wave.

(Note the last line, public editors are eager to put aside the relationship…)

Linux system without virus attack?

of course not!

Is there a virus attack in Linux? Of course there is! There is no system that cannot be poisoned, only people who want to write viruses or not.

Yes, yes, as long as it is a computer system, there is a possibility of being infected by a virus. Including Windows, Linux, and Apple systems that everyone has always thought would not be infected by viruses (in fact, the world’s first virus was born on Apple computers).

There are also some Linux viruses, such as ransomware, mining viruses, botnets and other viruses all have Linux varieties. But why doesn’t everyone feel it? Quite simply, there are too few Linux users!

If nothing else, the ransomware virus has been heard more or less. And, by coincidence, I have been exposed to ransomware myself, and a cousin of mine who is in business has also been exposed to ransomware.

My server was mainly bought for play, to practice some Linux commands and Linux operations. After being hit by a virus, I immediately formatted and reinstalled it without any loss.

And my cousin is miserable. He has been in business for seven or eight years, and all the most important information such as customer information, turnover, points, inventory, suppliers, etc. are all encrypted. For him, it is simply a Devastating blow!

In the end, after bargaining with the hackers, $4,000 settled the matter.

Then again, Linux viruses do exist, but they are much less common than Windows. The reason everyone can think of is that the operating system Windows on the market now accounts for more than 80%, so there is no need for hackers to develop viruses for the niche Linux system, which is thankless.

Also, who is using the Linux system? They are basically developers, or geeks with strong hands-on ability, and these people are basically people with very developed minds. I am afraid that it will be difficult for them to be recruited.

Are Linux systems safe?

First of all, there are many unsafe factors. We discuss this issue from both external and internal perspectives.

First of all, external factors, to put it bluntly, are virus Trojans and the like, which have been introduced before and will not be repeated.

And then the internal factor, where does the insecurity factor come from? In fact, it mainly comes from the operator itself…

As we all know, the root user has the supreme power and can perform almost everything on the system. So, in case you run rm -rf /* in admin mode , then I still advise you to hurry up and run…

Moreover, from the common definition of public security (that is, just randomly scramble something from the Internet, and then run it without looking at it), Linux is not safe at all. Basically, Linux without any configuration will not be able to handle this situation. Anything that blocks, and whether it’s Macos or Windows there will be all kinds of signing certificates, and mechanisms like UAC make it impossible for you to run anything weird from the Internet very smoothly.

So if you download some strange and unidentified programs and run around on the system, it will be a matter of time before the system crashes by you.

Generally speaking, I have to write a script and make a configuration, and I will test it on my own virtual machine. I will operate it on the company’s server when there is no problem at all. Otherwise, once there is a problem, I will play it. big.

Does a Linux system have no graphical interface?

Ubuntu: what are you talking about?

Fedora: I didn’t get it!

CentOS: Say it again?

OpenSuse, Arch, Manjaro, Deepin, Debian, have taken off their coats to show their muscles,

The unicorn stopped everyone: everyone calm down, we are all descendants of the dragon…
