Virus Creators Sharing More Code
arpy writes "The Washington Times is carrying a report on a 5% increase in publicly available virus code in 2003 (based on a Symantec report). There are now about seven versions of MyDoom, and at least 14 each of Netsky and Beagle. Explains why my email account is overloaded with these little bastards. PC World is reporting changes in the countries that virus are originating from: Australia shot from 14th place to 5th over the last six months of 2003! The source of these stories seems to be the March 2004 Symantec Internet Security Threat Report." (This last requires registration to download.)
The folks whose machines are that vulnerable probably need a little "housekeeping" help...
"Obviously, I'm not an IBM computer any more than I'm an ashtray" (Bob Dylan)
Wouldn't the open source of these viruses be an advantage to the Antivirus folks? (Symantec, Norton, etc.) I mean, if they know the basics of the virus, wouldn't it be easier to defend against them? (I don't have much experience in the realm of viruses...just curious!)

Open Source software really is viral!

Looks like we found at least one area where going the Open Source route is bad :-)

Any little kiddie who is going to copy a virus and change some code around isnt going to get very far, because the virus scanner is still going to pick it up. It would involve magor changes to change the virus enough for the scanner not to pick it up as the orignal virus. Just look at the last few varients of MyDoom, they hardly made a dent. As long as end users have updated scanners it should not pose as much of a problem.
"Virus Creators Sharing More Code"
Does this mean Norton and McAfee are going to merge companies ?
The nature of most viruses and worms means that they are shared quite ubiquitously. If you have received any of these viruses, then you have the code that makes them work. It's not hard to reverse engineer most code, and it's even easier if the language is something like VB script.
I remember getting the Anna Kornukova virus 4 years ago and just inspecting the script to see exactly how it worked. It would not be tough for a script kiddie to take that and modify it enough to get past virus filters. I'm sure there is virus code sharing, and I'm sure it's increasing, but if you really want to get your hands on the code, the author doesn't even need to intend to share it, he already has!
It suggests that anti-virus programs should be able to cope (if people bothered to use them).
Over the past several years we've learned that bacteria (and even plants?) can be 'promiscuous' about sharing useful genes, such as antibiotic resistance. Software is just catching up.
To continue to stretch the metaphor, apparently the immune system is keyed to stereochemistry of surface molecules. Change surface molecules, fool the immune system until it adapts. Spam has been taking this approach, injecting random text in an attempt to fool Baysean filtering. No doubt virii will learn the same trick. (Break code into mini-object modules, and use a randomizing link-edit step, for instance.)
The living have better things to do than to continue hating the dead.
You must have lots of friends and or family. I suggest you get a lesser life form companion and lose all ties to other sentient beings. Especially dumb ones with computers.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.
It's so obvious.. all we have to do is trick these virus writers into putting some SCO code into one of these viruses. They can put it between /** **/.. it doesn't matter. If they do that, SCO will pursue them to the ends of the earth!
1. Detect
2. Clean
3. Deliver if cleaned
4. Quarantine if not
Problem is, about 99% of viruses that have come into our firm in the last 6 months have been nothing but virus - no legitimate content. Despite this, our antivirus tool has no option to use its 'knowledge' of the 100% illegitimate messages and simply delete these outright.
In order to avoid the possibility of quarantining legitimate content, we are still detecting and cleaining, which still lets hundreds of confusing messages through to the users.
I know there are other products which will eliminate this kind of traffic altogether, but it seems to me that a few minor changes to (at least our) current antivirus products could dramatically improve the situation for us.
Are the other major mail-server based "pure" antivirus products any better than Mcafee?
---------- It tingles because it's working.
...when Symantec puts out a report that viruses are on the decline. I'm not saying that viruses are on the rise or on the decline or are not a danger to users, but I will definitely take such reports with a punch of salt, coming from a company which stands a lot to gain by scaring internet users with predictions of rise in virus attacks.
they hardly made a dent. As long as end users have updated scanners it should not pose as much of a problem Obviously you probably are not in the system administration field, ISP field, or anything similar. Right now I work in the ISP field, and you have no idea of the nuisances cause by the same repetitive viruses going on right now. Try explaining to Joe Blow common users why they're receiving messages from management, staff, security@someisp.com telling them their account will be terminated if they don't open foo file. Most don't know what a spoof is, and most don't understand why their dial up connections are now giving them errors.
Along with antivirus sofware which - some go through autoupdates, try explaining to users why they need to run their antivirus software after an update. See most people outside of the geek world would believe that an autoupdate from Symantec, or McAfee or others is automagically going to take care of itself, and it's not. Sure people here may know, but not everyone is Top Geek.
Whenever I talk to friends who don't know much about computing I try to liken it to human diseases and medicine, and those vaccination shots Americans have to take as kids going to school: "If you had diabetes you need insulin, if you go to the pharmacy and get that insulin but bring it home and put it on the table, your doing nothing. Think of an autoupdate from an antivirus company as doing just that. You got the medicine now, why leave it on the table. You have to use it." Most of the times they understand afterwards and ask silly things like well why doesn't the program do it itslef. Some antivirus software does after some configuration some doesn't.
For anyone to think that; someone outside of the computing - is going to have an understanding of this, you're wrong. If this were the case, there would be no more viruses. People are too trusting and naive sometimes, and no antivirus software is not going to detect anything. Has anyone not seen viruses that disable firewalls, antivirus software altogether, because I know I have dealth with people becoming infected with such. You can't base your experience with that of Joe Blow, it's apples and oranges.

I think that open source viruses are the way to go. GPL them and apply modern ideas from software engineering. Well documented viruses would be handy, both for filtering and to aid future virus designers.
"Explains why my email account is overloaded with these little bastards."
:). I know its not a 100% protection but it helps, obviously.
Well, partially it could also be to do with the fact that you are not careful about where your email address ends up. I have been as strict as possible about people not including me in their outlook/outlook expresss address books, or not including me on the mailing lists if i knew that participants are not security minded people. And i never had any sobigs, mydooms or the likes in my inbox yet i did use that account for emailing
Users are generally like people who leave their car unlocked and then complain that their radio is missing when they get back.
Yes, they're stupid, but in the end the thief is the guilty one.
Virus writers are a great justification for the total elimination of privacy on the Internet. Imagine if you could use ISP logs to trace a virus right back to the first transmission, and then to the source. You could find the prick, drag him to the city limits, and dangle his corpse from a tree as a warning.
Sadly, while I wouldn't mind executing the jerks who assault our information infrastructure, I do value my semi-privacy.

This must be a direct result of Mel Gibson's "The Passion Of The Christ". This holy movie has inspired a new culture of charity that is reaching down even to the virus writers, who so selflessly test the security of the world's computers so that we may all sleep more soundly, or... something.
*sniff* It gets me right here.
No, here. A little to the left. A little more.
Now scratch.

Pffft! Silly rabbit! You we're supposed to set it to puree.

at it's best -- these things have been peer reviewed quite well by now :)
One time I got to work and checked our local geek account (where we all joke, pass notes, etc.) and I read this email forwarded by the technical support "Hi I'm writing to know if everything is alright with the system. I'm not getting anymore spam so I wanted to know if there's a problem." I kid you not, the end user was wondering why, they weren't receiving spam. It's difficult to filter too much, because what do you do when someone is constantly complaining about not receive a business proposal coming via way of zip. What happens if by mere coincidence it was flagged as spam, or a virus. That's the problem with filtering, personally I think education is a better resolve, but that's just me.

One was written from the MyDoom worm, and patched the hole after using it to get in.
That sounds freakishly like some biological viruses that recombine its genetic information into the host chromosomes which effectively seals off the cell from further attack by viruses, so that it can do its work safely without interference.
If virus makers actually learn how to recombine their code into standard windows libraries and the code is then free to work without interference, the Windows users wouldn't know that they are actually infected until some future date when their credit card numbers are stolen/hard drives reformatted/etc.
In fact, the whole idea of sharing the code of viruses is similar to the idea of recombinatorial DNA in viruses and bacteria: effective code from one virus can be transferred and incorporated into another virus/bacterium (plasmids) to make an even stronger pathogen. Scary stuff.
I am defenseless. Use your button. Mod me down with all of your hatred.
It's natural selection.
Those PC's that succumb and die from infections, leave only the strongest PC's to repopulate the earth. It's happened all throughout nature since time began. Consider this the "electronic black plague".

Viruses is closed-source, proprietary software that only runs on Windows.
A lot of nice guys are trying all day long to send me ".pif" files so that I can have fun, but I keep clicking and clicking again, nothing happens on my OpenBSD box. It's so disappointing.

Maybe the virus writers are getting older, going to university and the lectures on software engineering and code reuse are hitting home??? :-)
Strangely Enough...Hotmail's Junk Mail filter was enough to keep malicious emails out of my inbox, though I had to block some legitimate emails in the process.
Quite a bit of assembly required, actually....
Once, ignoring viruses and anti-virus software, relying on good practices only was a cool hobby; nowdays, it's a disaster waiting to happen, in a large part M$ is to blame.
I retired a box I used from 90-95 and I'm now in the process retiring the 95-04 one. Amazingly, I was able to run MS DOS and Windows 95 without much hassle and without permanent anti-virus-come-to-the-rescue operations.
People borrowing my diskettes (remember the 5 1/4 " floppies ?) did all sorts of things:
- have infected the floppies,
- have goten themselves infected,
- detected viruses on them, etc;
while my back yard remained clean. However, I've had a few strict policies:
- frizbee network: never stick anything into your floppy drive that's "been around" unless you plan to 'format';
- email: do not use MS Outlook, do not open unexpected attachments from people you know, do not touch stuff from people you don't know etc., etc.
Nowdays, using both W2k and Linux, I claim the (don't-check-for-viruses-and-don't-have-any) policy DEAD. At least for MS w/ Outlook and Explorer, a prompt anti-virus solution is a must.
If nimda was the ultimate lesson for typical corporate intranet environments, the Netsky & Bagle definitely break barriers in the category of private, spam-free, home user addresses.
And it's all probably because of this wrong (viruses-happen-to-losers-not-me) additute of just one of my otherwise cool e-mail-buddies that made it all possible for me: watching a bogus email w/ a virus dropping every 2-3 hrs into my private inbox, without a clue who really the sender is or whose set of contacts would correspond to the addresses in the spoofed TO: fields.
I haven't had any trouble with any of the non-M$ boxes I work with. But like it or not, I still have to use some M$ platform and sadly, no prevention is helpful - it cure, cure, cure, all the time...
A lot /. readers are not familiar with Windows and may ask what "virus" means in computer science. So in order to better understand this article, here's a short presentation.
:
Virus are popular peer-to-peer sharing systems designed and optimized for Windows platforms.
Great features of these systems over other P2P systems
- It's free software, although the license is often missing.
- They are very well maintained. New versions are released almost every day.
- They are easy to use : no need for a GUI, no need for a CLI, everything is fully automated.
- Updates are also automatic.
- No need to tweak your firewall, popular viruses can work on port 25 using a SMTP-like protocol.
In order to join this community, you just have to run an installer called "outlook.exe". To improve your experience, the "internet explorer" add-on is also recommended.
And how handy, the installer and its add-on are part of the vanilla "Windows" installation CD set. No need to download anything and no registration is required. Very convenient.
Once the installer ("outlook.exe") has been started, an Evolution-like interface pops up. This is bloat, it can be safely ignored. Directly go to the "add contact" panel and fill in email addresses of friends you want to share executable with. Wait a few minutes (check the internet link is ok) et voila, viruses are automatically downloaded, installed and configured.
You know understand why this p2p system is so popular in the Windows world : easy to install, easy to use, and the operating system keeps a lot of unfixed security holes in order to avoid breaking backward-compatibility with older viruses.

What someone really needs to do is make a virus that consists of several parts. Each part by itself would have no effect upon an infected computer except to run at startup and check for the existence of the other pieces.
If the final piece to run determined that all pieces were in place it would abort the startup process and display a dialog box with a button titled "I want to format my hard drive now" and a message saying something like:
"You are a bloody idiot and your computer has been infected with a virus. Not once. Not twice. Not thrice, but FOUR times!
You are too stupid to operate this computer further until you take it and have it professionally cleaned of viruses, trojans, spyware and other malware, have proper antivirus software and a firewall installed, receive some sort of training on keeping the antivirus software updated, and finally, are told in no uncertain terms to not immediately open each and every email attachment and to no longer download and install each and every cute little gorilla, gator, monkey or other furry or scaly creature that promises to make your internet experience ever so much better."
When they then click the "I want to format my hard drive now" button the activated virus would display a second dialog that says "You did not read the button at all did you?" and shut the computer off.
Our street runs a "community based ISP.". Approx. 320 users on a switched 100 Mbit LAN. We run some Linux servers for standard services like mail, ftp, www, proxy, monitoring, firewall, etc).
19 October last year, we deployed RAV anti-virus from www.ravantivirus.com (now owned by Microsoft, who promptly announced that all RAV anti-virus software for Linux will be terminated).
Since October the 19th, 18.500 email viruses has been detected.
Dec 2003: 1700 viruses detected
Jan 2004: 3635 ""
Feb 2004: 7819 "",just slightly below one virus per day per user.
Mar 2004: (per 17 marts) shows a slightly downward trend with 4430 viruses detected (223 per day).
Only 8% of the viruses originate from within our network.
37% are Mydoom viruses
21% are Netsky variants
7% are Mymail viruses
Now, viruses are a problem. Everybody I talk to know to some extent that viruses are "bad". You sometimes read about high profile arrests of virus writers. Fine.
But spyware is IMHO an even bigger problem for a lot of users. They have a hard time understanding the concept, why they got it, and how to get rid of it, and why it seems to be totally legal to plant stealthy spyware on their PC. To me, and the people I explain what spyware is, spyware is hacking (cracking) in its most criminal sense, since the spying are done for clearly economic reasons.
If spyware were manufactured by pimple faced teenagers for no economic reason, I am sure they would be busted by the police as evil hackers. But since spyware hacking are made by so called businesses, it seems to be a totally OK practice by politicians and law enforcement agencies.
Yay! exports are up. I knew all the toadying to the US would pay off for us eventually.
