Researchers Hijack Storm Worm To Track Profits

An anonymous reader points out a story in the Washington Post, which begins: "A single response from 12 million e-mails is all it takes for spammers to turn annual profits of millions of dollars promoting knockoff pharmaceuticals, according to an unprecedented new study on the economics of spam. Over a period of about a month in the Spring of 2008, researchers at the University of California, San Diego and UC Berkeley sought to measure the conversion rate of spam by quietly infiltrating the Storm worm botnet, a vast collection of compromised computers once responsible for sending an estimated 20 percent of all spam." The academic paper (PDF) is also available. We've previously discussed another group of researchers who were able to infiltrate the botnet for a different purpose.

      that's a good point. i'm guessing part of the reason why Gmail has such a good spam filter is because they implement collective filtering by allowing users to easily mark spam messages, and also because with such a large user-base they can implement statistical filtering techniques much more effectively.

      what i don't get is why ISPs big and small don't just cooperate with each other and trade/pool information needed to fight spam. it would improve everyone's quality of service, so why not work together to achieve common ends. combating spam is one situation where different businesses don't need to compete with one another because they have shared interests.

      even if you're just a small ISP with only a few thousand users, if you work with 10-20 different similar sized ISPs to collectively implement a shared spam-filter, you would achieve much better results than what each ISP could obtain on their own. not only are there more e-mails to perform statistical analysis and Bayesian filtering on, but there are also more users to identify/catch the spam messages that slip past the filters. that way the job of catching stray spam e-mails is distributed across a much wider user-base. instead of each user having to mark 10 spam messages a day, perhaps they only have to mark 10 messages a month.

    the researchers seem to take the legality of their actions under serious consideration. From TFA:

    "Measurement Ethics:
    We have been careful to design experiments that we believe are both consistent with current U.S. legal doctrine and are fundamentally ethical as well. While it is beyond the scope of this paper to fully describe the complex legal landscape in which active security measurements operate, we believe the ethical basis for our work is far easier to explain: we strictly reduce harm. First, our instrumented proxy bots do not create any new harm. That is, absent our involvement, the same set of users would receive the same set of spam e-mails sent by the same worker bots. Storm is a large self-organizing system and when a proxy fails its worker bots automatically switch to other idle proxies (indeed, when our proxies fail we see workers quickly switch away). Second, our proxies are passive actors and do not themselves engage in any behavior that is intrinsically objectionable; they do not send spam e-mail, they do not compromise hosts, nor do they even contact worker bots asynchronously. Indeed, their only function is to provide a conduit between worker bots making requests and master servers providing responses. Finally, where we do modify C&C messages in transit, these actions themselves strictly reduce harm. Users who click on spam altered by these changes will be directed to one of our innocuous doppelganger Web sites. Unlike the sites normally advertised
    by Storm, our sites do not infect users with malware and do not collect user credit card information. Thus, no user should receive more
    spam due to our involvement, but some users will receive spam that is less dangerous that it would otherwise be."

How can we be sure that a person who decided to purchase these drugs (against all warnings) really believes that not buying them is the best thing for him? What if this person really wants to purchase a drug that he thinks will enlarge him? Who gives the researchers the right to decide what other people should spend their money on? Under several legal interpretations, forcing a person not to buy something perceived as harmful is not legal: denying to sell cigarettes to a person of legal age may be illegal, under discrimination laws.
