    One clue is, in your e-mail client, the sudden presence of "delivery failure" alerts for e-mails sent to people you do not know.
    Doesn't this come about from people just spoofing your address anyway? If not, Hotmail has a virus problem. :o)

    Any biologist will tell you that in an environment where there is only one type of organism, any infection that they are susceptable to that comes along will have catastrophic effects. To avoid this you need diversity. In computing the problem with having windows/intel as the vast majority is that any attack that targets that is going to cause a lot of trouble. Standards that have been implemented on many platforms and architectures are what is needed but that goes against Microsoft's desire for control of everything. However, that desire is doomed to fail because if they fail to take control they fail and if they win complete control they fail because of the lack of diversity.

    it is good to have lots of operating systems and processors out there, anything else would be suicide. With proper diversity we could control both the virus and spam problems.

That may explain the embarrasingly outdated technology quotes, like One reason for this success is that the latest variants include Zip files, but with reference to the foolproof quote, what I'm inclined to believe is that the makers of ZoneAlarm paid for this sort of tripe (advert on the article).

    The problem is that we are trying to catch spammers, instead of people who sell the very advertised products and services. Just follow the money, people. That way it won't matter how well spammers hide their identity. It all works because someone gets the money, which is absolutely trivial to track. If few CEOs went to jail because their companies' products were in spam, I'm sure other CEOs would at the very least stop to think about it. It is really that simple.

    "it is good to have lots of operating systems and processors out there, anything else would be suicide. With proper diversity we could control both the virus and spam problems."

    If I follow your logic, you could also make a case that having different taxation laws in every state, city and town would reduce tax evasion. More likely the same amount would go on, but it would be harder to detect and control and police. Who cares if some small guy from Assfuck, Idaho is cheating on his tax.

    With diverse operating systems, there will be precisely the same number of dickheads out there writing malware, but that each would be more focussed for an OS, and perhaps more difficult to detect.

    A Windows trojan is news. There are a gajillion desktops out there to attack. Who is interested in reporting a virus for a niche operating system with a few thousand users? Certainly not the mainstream. What about Antivirus tools, etc. Who is going to write them?

    As for this solving spam... As far as I was aware, the internet is already built using open, diverse (and exploitable) mail protocols.

    It's difficult to see how spammers could remain annonymous. At the moment, they're an annoyance, but if they enter the realm of law-breaking to this extent, it is likely that there will be a major crackdown. And this shall not be difficult, because of the very nature of spam -- to get you to buy a product. Therefore, there must be a link to the spammer.

    It won't work.

    Since most spammers advertise and sell a product, spammer can't be anonymous. At some point you will be able to send money in one direction, and goods in another. This is not particulary hard to track.

    Furthermore, spamming might be more or less legal in different jurisdictions, but you can usually get away with it. Willfully spreading viruses is not something you can get away with. Only very stupid spammers would ever try that technique (as explained in the previous paragraph, it wouldn't be particulary hard to trace the virus back to it's originator)

    Seeing as how spammers are paid for the messages that they send out, how is it possible to track the messages that have been sent using this type of method? If you've got millions of nodes around the world sending messages on your behalf, how do you tell how many you've sent so that you can bill your clients?

    Folks who work for ISPs will be angered by this post, but before you hit reply, take a deep breath, step outside yourself for a bit, and think about what I am about to type.

    While ISPs are not to blame for this problem, ISPs are in the position to correct this problem. This is not about fixing blame, it is about fixing the problem. Keep that in mind.

    Now, as I've said in previous posts about this sort of thing, it all boils down to preventing the spread of infection - mathematically, if the expected value of the number of hosts infected by any given host is greater than one, then the infection will be much like a supercritical mass of fissionable material. So the trick is to reduce the expected value to less than one.

    Now, there are plenty of ways to do this, most of which involve the ISP taking some action.
    • Require users to keep their machines virus free, and disconnect them QUICKLY when they fail to do so.
    • Scan outbound email, and drop all mails that have attachments with extensions that do not match the Mimetype (e.g. an attachment with an extension of type .scr but a Mimetype of audio/midi). (Yes, this would not matter had Microsoft correctly implemented Mimetype checking in IE, but they didn't - the OS looks at the file extender, not the Mimetype.)
    • In the same vein, block all outbound mails that contain directly executable attachements. Friends don't send friends programs, and if they must do so, they zip them first.
    • Limit the average user's ability to bypass such filtering - do not allow users to directly send to SMTP, SMB, and NFS ports unless the user have explicitly asked for such access and taken responsiblity for doing so.
    • Upon getting complaints about violations, QUICKLY move to resolve the problem - as in, within 24 hours. If the customer will not or cannot solve the problem within that time, shut them down until they can.


    In short, take responsiblity for FIXING the problem, and force your downstream customers to do the same.

    I have been receiving a steady stream of virus laden emails from udw.ac.za (a university in South Africa). I have repeatedly contacted them as well as their up stream provider (saix.com). All SAIX does is send a nastygram to UDW. All UDW does is experiment in topological auto-proctology. Were SAIX to say "Alright - we've had five complaints this past week. You obviously are not doing anything to solve the problem, so until you do, we are blocking port 25 outbound from you" then UDW would be HIGHLY motivated to correct the problem.

    But right now, most ISPs have the attitude of Mind Over Matter - "We don't mind, so it don't matter. Over and out." As such, the problem persists and grows. ISPs mail servers handle a steadily increasing stream of viruses and spam, for which they complain bitterly about having to buy new equipment (while raising their fees), but they don't actually try to SOLVE the problem.

    If ISPs were to say, "The line must be drawn here. Here, and no further." - if they were to start blocking viruses and spam, disconnecting users that spread them, and requiring their downstream to do the same, then the expected value of the number of hosts any one host can infect would drop to a tiny fraction of 1, and the reaction would damp out. Viruses would not longer spread like wildfire, the news would no longer report upon them, and the virus writers would no longer get egobo from writing them.

    However, as long as ISPs continue to do their best Sgt. Schultz of Stalag 13 ("I SEE NOTHING! NOTHING!") impersonation, as long as ISPs say "It's not our fault - we are not to blame, why should we do anything about it!" then the problem will only grow.

    (/me sits back and waits for the inevitable flames from ISPs wishing to do exactly that...)

    Given that I've suffered this myself, with a virus-free existence of some years, I suspect that my email address has been used on several occasions by spammers as a from address due to my use of Spamcop to attempt to report these spammers. This article really doesn't seem too well researched I'm afraid.

    1. Write devastating super-virus

    3. Destroy unsuspecting internet
    4. ???
    5. Profit!

    ObSlashdotJoke aside, I always wondered where step 4 came in. Clearly, from the number of viruses doing the rounds now, bragging rights alone is enough of a draw for many; equally clearly, from the vast weight of bugs in viruses, it primarly draws teenage l33t hax0rs with more testosterone than talent.

    All the devestation of every trojan and virus in history has been without a clear step 4. The addition of a step 4 worries me a lot, and as has been said before [slashdot.org] even non-Windows people like me can't feel smug and safe forever.

    It's a nice idea, but the biggest problem that I can see is that it would make ISPs responsible, in a very real, legal and scary sense, for the content of the packets that they carry.

    As it stands, an ISP is not that much different than the phone company. They connect one user to another and don't worry about what is being said. What you are proposing is that all service providers would spy on their users and take corrective action if they are caught saying the wrong things.

    This would be no different than the phone company terminating your call if they hear you mention the words "pie", "face", "chimp" and "white house" all in the same conversation.

    If an ISP were to take such an interest in what their users have to say, then it would leave them in a tricky legal position -- If they have a policy of shutting down users who traffic in Windows Malware 2002 (tm), then why do they turn a blind eye to such horrible things as kiddie porn, copyrighted music and Harry Potter fan-fiction? The lawsuits would spread like wildfire, and the imminent death of the internet would arrive at eleven.

    I'm not an ISP, but I'm a customer of one. Much as I hate spam, if my ISP implemented the measures you described, they would cease to be my ISP. I don't want my ISP telling me what type of attachments I can send (my company already does such checks on internal mail, and it drives me mad, but it's their network so they can do as they please). As for virii, trojans etc, well if I cause an actual problem to their network, or another of their clients, then sure they have good reason to disconnect me. But putting some requirement on me to keep my machine "virus free" (what does that mean anyway?) they will almost certainly end up mandating use of some (commercial, windows only) antivirus package. Great - there goes support for other OSs.

    Where I do agree is in responding to problems. However I've not had so many problems here. In the few occasions where I've had serious problems from people scanning, flooding, whatever, I've complained to the appropriate place (in one case I remember an italian ISP, in another a US one) and it's been fixed. Guess I've been lucky.

    I think the authors point was the problem is that there are a gajillion wintel desktops out there. It's great that a windows trojan is news, but I don't think we've seen one that is REALLY malware. Most of them only focus on self-replication and not destruction of the host.

    The problem with the one host enviornment is, if some virus writer decides he is having a bad day and comes up with an exploit that can render all of the windows boxes on the net inoperable then there is a huge problem since 80% of the internet traffic will be gone. (or maybe this would be a solution to some people ;)) Geeky jokes aside, if this ever happened it would cost businesses and just plan old people millions of dollars. Non-Tech savvy People would be reluctant to connect to the net again if they bought a new PC, etc. If half the boxes out there were on a mac, the blow to the net wouldn't be as bad...

    So now DDoS also means Distributed Distribution of Spam?

    In one of the first of these that I saw back in May, the spammer apparently hadn't yet learned the art of using the Bcc: header, and all the addresses it was being sent to were clearly harvested from one newsgroup that I regularly read (and post in). That's how I knew it was spammed, and not just an "address book dipper" virus. And for some time, people have been spamming binaries pictures newsgroups with .exe attachments.

    I'm glad to do my part in creating a diverse computing environment by running OS X instead of the leading virus-ridden OS. Is there any truth to the rumor that Microsoft is going to rename Outlook Express as ActiveVirus[tm]? :-)

    " they will almost certainly end up mandating use of some (commercial, windows only) antivirus package."

    No, that is exactly why I phrased it as I did - "require the user to keep his machine virus free."

    If a machine is sending virus laden emails, then it is not virus free. Otherwise, innocent until proven guilty.

    As for the attachements - I am sorry, but your right to swing your arm ends where my nose begins, your right to play your stereo ends where it enters my house. Society can quite legitimately ask its members to curtail dangerous behaviors. I can think of no circumstance in which sending an executable program as-is is needed or even wise. Not only will zipping the program reduce the size of the program (and thus the load on the mail server) it will add CRC protection to the program so that an error in transmission has a higher chance of being detected and corrected.

    "my company already does such checks on internal mail, and it drives me mad, but it's their network so they can do as they please."
    Guess what - Your ISP's networks is THEIR network, so by your own arguement THEY can do as THEY please.
