I know assembly language a bit. I heard from somewhere that ASM can be used in virus writing. So i would like to read something about the concepts of virus making. Have anyone here already had an experience in this ?

And I am trying to learn how to prevent people from learning how to create viruses. A lot of problems already arised from people doing mistakes when creating a virus.

I don't think you'll get much information here since this is in direct violation with our TOS. I'm not sure but probably the admins will close/delete your post. Please don't do this anymore.

Sorry then, i didn't know anything about this I came to this forum from russian programming forums. There is a freedom about this. Even CS students write viruses while practising programming. I just want this for education not for destruction

Freedom, yes. Danger for the whole community, no.

Yea it can be educational probably, but still you'd probably have better luck looking at forums where virus creation and the more dark side of programming are the common element.
Personally I've yet to program anything even virus-esque... except a couple fork() bombs that I tricked people into using but those were more of a nuisance and non-self replicating then anything haha...

I once wrote I virus, but didn't try to send it to anyone. Just for educational purposes It was extremelly simple, cause I made it in QBasic, but it did the job. These sorts of "viruses" are easy to make, but the user must be really naive to actually start them.

For example, my so-called virus did the following. When started, it changed a windows file called "hosts". If you put



It will tako you to the mentioned ip address when you type www.google.com in your browser.
I put my web site's IP address and some popular search engine's urls. I also made a program that returned everything back to normal.

It is a nice program, but works only with WinXP installed on C: (I hade only the basic programming knowledge).

You see, even with the most simple programming languages you can make something good.

This is not really a virus. Hope I didn't break any rules

As i know virus is a program that can copy itself and always stays in memory :-)

Ok then, this is just a program that plays with your computer.

On the other hand, think about a program like mine which is always running in the background and does the ip thing with any web site the user goes to. Now that would be nice.

You want to google smth
You go to google
You google it and go to a result
Then you wanna google again
You type www.google.com - and it takes you to a completely different web site!

Nice!

We'd a similar thread discussing some technical aspects of hacking quite sometime back. I let the thread go on with a minor warning that NO POTENTIALLY HARMFUL information is discussed here. You guys are all responsible people and know where to draw the line. So I won't close the thread but let it go on, like I did before. But any signs of deviating from that thin line - will result in sudden death of this thread

There's a that lot you can discuss about authoring a virus - without bringing in the harmful codes and associated stuff into the discussion.
