Next Generation Spam Zombies Will Use Data Mining

Posted by Zonk on Fri Apr 28, 2006 01:46 PM
from the hate-these-new-fast-zombies dept.
branewashd writes "The Globe and Mail is covering some new research on the future of spam. The paper 'Spam Zombies from Outer Space', from researchers at the University of Calgary, will be presented on Sunday at the European Institute for Computer Anti-Virus Research conference. According to the paper, the next generation of spam zombies will employ 'sophisticated data mining of their victims saved email'. When a computer is turned into a spam zombie, it will first be mined of its address book, mail client configuration, and mail archives. Then the spam program will use Natural Language Processing techniques to send spam messages to the victim's contacts that look a lot like messages that the user has previously sent. The researchers predict that this will be extremely hard to detect, but they do offer a few suggestions for combating it."

    Technical advances
    Better tricks to fool spam filters, like the examination of text the user has written mentioned in TFA. This is close to impossible to stop, the only way is to try to be faster in developing better anti spam tools.
    Lack of security
    Most spam today is send from captured machines, and in the future these machines will not only be used to send but also to improve spam. This could be helped by better educated users, better default system security or easier to understand security configurations. At least there is hope.
    Response
    The only reason for all this spam is that it still pays. Even though it is a very small number of people, it is enough to finance the whole illegal business of building bot nets, stealing addresses etc. If there was a way to stop people to buy that stuff, the other two points would be irrelevant. Unfortunately this is not going to happen, which is the most frustrating part.

        It's being used to disable the Bayesian-style filters that tend to work on keywords. Basically the idea is to flood the filter with a lot of junk messages that give false positives, thus making the filters less effective as the user attempts to tag all these junk messages as spam.

        I'm astonished by those all the time. My Thunderbird is throwing out about 2000 mails a day, and I am often confused about those it didn't catch. I could not recognize them as spam either, since they contain no product names, no links, nothing.

        But since I believe that nothing that can be explained with stupidity should be explained by conspiracy theories, I assume these are accidents.

          If you mark enough of these random collection of useful word messages as spam, your beysian spam filer will start filing real, useful email as spam, and you will eventually decide the filter doesn't work and turn it off...

          Of course, if you feed your filter just the headers and stuff that actually looks like spam, and not the blocks of random words, it can still learn useful things.

    1. This is Microsoft's fault.. Microsoft should fix their operating system to ask for a password any time a program is installed, registry settings are changed, key files are modified, etc.. Also, 'install on demand' should be eliminated from Internet Explorer. Ever notice how spyware pretty much didn't exist before Microsoft gave the developers complete control over a person's PC? The end user is stupid. The whole premise of Windows assumes that.. So then why did Microsoft decide that the end user should be able to have his system completely compromised with ONE SINGLE GODDAMN FUCKING WRONG CLICK WHEN BROWSING A SHADY SITE?

    2. This is the fault of the legal system. Spyware is ALREADY illegal. Congress has talked about making it 'illegaler.' Someone needs to jump forth and realize the moneymaking potential that it is to sue the pants off the incessant spammers.

    Again.. 99.9% of spyware problems can be fixed by just running in limited user mode. Ubuntu has the right idea..

    ...is that they fail to mention the fact that _most_ (if not all) of these "spam zombies" happen to be Windows based machines. Agreed, most of the machines in the world run Windows, but shouldn't the news article atleast mention the fact that the 'zombification' is attributable (most of the time) to Windows vulnerabilities? Don't know if the UCalgary research team mentioned it in their paper.

      What does this exactly entail? Does the computer first have to be compromised? Spyware/spamware installed through a backdoor? I've lightly read through the paper and it does mention that some sort of malware may be present on the victim's machine.

      Yes. This has been standard operating procedure for many spammers for about two years now. Virus, worm, and spyware authors set up backdoors through which compromised computers can be loaded with spam-sending software. Then they sell access to these botnets on the black market. Spammers use software designed to blast out commands to dozens or hundreds of bots sitting in homes, businesses and elsewhere, which then spew their virtual sludge across the internet.

      The hardcore spammers effectively have infinite processing power and bandwidth, since they can distribute the load across a botnet, and when the same spam run is coming a few messages at a time from hundreds of IP addresses, it's a lot harder to blacklist by IP. That's why many ISPs have started filtering outgoing SMTP traffic, and why blacklists have cropped up that just block any incoming mail from dynamic IP space.
    • But besides that, maybe an ISP should by default block all but a few outbound ports unless the user requests them specifically (either via a web interface @ the ISP or by phone)?

      Two problems with that:

      1) While blocking access to port 25 outside of the ISP's network is one thing, you can't block port 80 or 443 (or some others) without seriously disrupting your customers' experience. So you have to let some traffic out. And there's nothing saying a zombie can't be programmed to connect on either of those port
