Okay so imagine a big computer that can do many things at once, like playing games or help you with your homework. This computer is called a server and it runs on something called Linux, which is kind of like the brain of the computer.
Now, let's imagine that there are some bad guys out there who want to sneak into your server and mess everything up, like deleting your favorite game or stealing your homework. This is where the problem called Darlloz comes in.
Darlloz is like a sneaky little bug that can crawl into the Linux brain and make things go wrong. It's kind of like when you get sick and your body doesn't work the way it's supposed to.
But don't worry! There are smart people called cybersecurity experts who are working hard to find ways to protect your server and keep those bad bugs out. And if you follow some basic rules, like not clicking on strange links or opening emails from people you don't know, you can keep your server safe too!
