Computer virus???

[Panda]

8) I always have this question in my mind.... How are the computer viruses created. Recently, we learnt C++. WE have learnt until the object part.
I am wondering whether we can use C++ to creat virus.
Any comment??? 8O

[screw3d]

You most certainly can. Don't ask me how though ;)

[DecentMerson]

hehe.... i agree... most certainl, u can....

just google around and kazza around and u can find an ebook which will teach u how....

:roll: :roll: :roll: :roll:

heh I always wonder why is it so easy to create viruses that you can even create one using low-level programming such as JavaScript and VBScript ... what are the guys at M$ thinking to have Windows automatically run these virus-made-easy scripting languages?

[screw3d]

Most viruses are written to exploit certain security flaws though..

Computer virus is actually a kind of program, no life... how can it act like a living creature that made us call it as a "virus"?

To write a program, you need someone to execute it when they need it. To write a virus, your program must be able to operate themselves without anyone's command. Why people like to use C++? Because C++ is considered as one of the 2nd generation programming language, which can directly deal with every single bit of the microP. I came across a kind of programming skill, which is called Terminate Stay Resident (TSR), although you kill it or close it, it still stays in the computer memory. It may not be the skill that virus-creator use but almost the same...

I found a book of how to write a virus when I studied my microsoft assembler years ago (that book is for reference only), but that book is written in mandarin, needs some time to translate it... haha...

laplace..

but the real virus itself is not an organism .. there are different medical beliefs in term of what virus actually is but they are all trying to avoid defining virus as an organism .. hahaha I'm digressing ...

anyway, why computer virus is called as such is really because it intrudes into other body [explain:c06845a352]operating system / bios[/explain:c06845a352] and replicates itself [explain:c06845a352]sending email attachments[/explain:c06845a352] while causing harm to the carrier [explain:c06845a352]files deleted etc.[/explain:c06845a352] ...

if there's ever a reason for me to support the death penalty, this creature would be it:

sasser worm creator arrested (http://msnbc.msn.com/id/4928653/)

some interesting note on computer virus..

the term was invented by Prof. Leonard Adleman (http://www.usc.edu/dept/molecular-science/fm-adleman.htm) (one of the people who created the RSA (http://www.google.com/search?hl=en&lr=&ie=UTF-8&oe=UTF-8&oi=defmore&q=define:RSA) cryptosystem.)
He's a comp sci professor here at USC.

His research focus mainly on the DNA computing..stuff that related to biology. .. he invented the term 'computer virus' :

An interesting reading on how he uses the DNA to solve the Traveling Salesman problem
(6 cities):

Thus, the invention of the term 'virus', really got the influence from Prof. Adlemen's involvement in the Bio-related stuff.

Please don't create any computer viruses. They are annoying. Useless programmes made for the pleasure of watching others in agony (updating security patches and buying the latest virus detecting softwares). What is the point of creating viruses? Might as well create a programme that would benefit all of humanity and not only the anti-virus companies.

Hackers used to create viruses to exploit security flaws in major softwares like Microsoft, probably due to the news circulating about Microsoft's bullying tactic on smaller software companies....

But now...with the Sasser worm ....it's gonna be a new generation of viruses coming! auto-replication and auto-executing! That's really damaging!!! ...wonder what the creators want from it? Even my college's computers are affected!

Have you guys heard of any conspiracy theories? Antivirus companies creating viruses so that ppl have to buy updates/subscriptions every year...and a new one about Linux users trying to make the world switch to Linux!!!

hmm.....just a thought.... :lol:

[ElansarGelmir]

Yeah, I think of that too... Like the anti-spam bot companies creating spams and offered to clear the spams... Recently, I've gotten a wormblaster in my comp. Even norton can't clear it up. Sigh, at last got to send it to the hospital and download blasterkiller. I wonder did the blasterkiller company made the worm?

[weich]

speculations can get nowhere...investigations need to be made haha...but I'm sure they'll be smart enough to wipe off the tracks =) if they got the best hackers working with them....they know the tricks of the trade won't they?

and also from a business point of view...you can say that they should be credited from creating something out of nothing? makes good business sense wouldn't it?

[ElansarGelmir]

I believe they are terrorists. They cause problems to domestic comp consumers. Don't you think so?

[weich]

what if viruses is a way to let the world sit up and notice certain flaws in programs like Microsoft? What if somebody evil uses the security flaws and exploit it like stealing passwords, credit card nos, etc?

..just wondering =)

[gohweihan]

The trend of virus writing has been changing from destructive viruses to viruses that merely spread and clog the network bandwidth. Virus writers nowadays just seem to enjoy outperforming each other in terms of which virus gets a higher ranking in the virus alert list.

Most people defend the virus writers by saying that they are merely exposing the flaws within an operating system. However, the fact remains that there are other ways of notifying those companies on their flaws. Having a virus that spreads throughout the world just to show that there is a flaw is somewhat a stupid thing to do.

Well, I used to have a few virus source codes written in C and C++, though I've lost them the last time my hard disk failed.

actually, a computer virus has to by definition replicate it's code and propogate in some way. I think trojans are not considered viruses becuase they don't do this automatically.

[littlebigone]

If I were smart enough I would write computer viruses simply for the challenge.

Where's the fun in letting M$ know about their flaws. They probably know about most of their flaws but are taking their sweet time to create patches. I support viruses to wake M$ up. :p

What many people don't understand is that although a virus attack may cause you inconviniences, the virus is really mostly harmless. Take the sasser worm which took advantage of some RPC bug. Any other hacker could have used that bug to just listen to your PC for passwords, and all the blah. Isn't that worst than having a virus attack. If we weren't attacked by the sasser, most of us would still have that security flaw in our OS. That's not goos is it?

Anyways, I think taht hackers and virus programmers have some place in this equilibrium of life. My 2 cents.
