Why no virus in ubuntu

[raci2020]

Hello people,

I once heard a professor of mine saying we cant edit virus files in unix and linux. But when i asked him why he failed to contend me. Can any one help????

less legacy black holes in the kernel than windows make for less exploits and better user account control make it harder for something to wiggle its way into your core system.

The teacher has probably heard that malware files are less likely to hurt your *nix system, mainly because most malware is designed to run on Windows. The "behind the scenes" stuff that runs programs and access files (e.g. the API) are usually different on different operating systems.

Have a look here for some ideas.

edit viruses? You make viruses... Technically you could if they are written in languages that are compatable, you just cant run them. Linux/Unix cannot run windows based viruses. and Linux made viruses can only work if they are given permission to do so.

I am guessing you are writing code,

If you edit the code on a *nix then take it to ******* the line breaks are different. This is why you don't edit *nix confs on ******* in notepad... that said you can you just have to make sure your editor of choice uses ******* style line breaks..

There are programs which can convert between the different methods of doing a line break e.g. unix2dos. Writing something to do the job isn't too hard (even I could probably manage something in C, a language I haven't used much)

EDIT: If you have gcc on your *nix system or Turbo C++ v3 on your MS-DOS/Windows system, the attached program should do the trick, converting a file to the current OS's native format. Won't work with Turbo C v2.01. Haven't checked it with other compilers. CAVEAT: use it only with text files - running it on other file types is likely to mess things up.

Viruses can certainly be made on Ubuntu and even without root.

Here is a test virus(now patched) that was made took advatage of a bug in gnome I believe.

Why would you want to edit or write a virus.

Why would you want to mess up something good like Linux or Ubuntu!

The mind boggles!

Because some people, usually rejected teenagers, think it's a way of "getting back at the world". They trash other people's computers because it makes them feel powerful. There are stronger words for this sort of person than "script kiddie".

I haven't looked at the video, but I presume you will have to run something yourself first.

That makes it a trojan, which can be created on OS ever made.
