Attacking Criminal Networks On the Internet 109

Hugh Pickens writes "Computer Scientists at Carnegie Mellon University are developing techniques to analyze and disrupt black markets on the internet, where criminals sell viruses, stolen data, and attack services estimated to total more than $37 million for the seven-month period they studied. To stem the flow of stolen credit cards and identity data, researchers have proposed two technical approaches to reducing the number of successful market transactions. One approach to disrupting the network is a slander attack where an attacker eliminates the verified status of a buyer or seller through false defamation. Another approach undercuts the cyber-crooks' network by creating a deceptive sales environment. 'Just like you need to verify that individuals are honest on E-bay, online criminals need to verify that they are dealing with "honest" criminals,' says Jason Franklin, one of the researchers."

The only way to be able to discredit them is to get in contact with them somehow or visit a site they visit regularly.

      You see two auctions, one for a kewl expensive collectable car. They look identical in the search page.

      One of them has a very low buy-it-now listing, and a gmail address to contact to be a 'qualified' bidder.

      Which one of them is fishing for your eBay creds? I see these all of the time; I collect and restore specific models of classic cars, and I see one of these almost every week. If you alert eBay through LiveChat, they'll usually take them down. But if you have report an auction through their mind-numbing 100 questions forms method, you'll never get a fraudulent auction done because you'll explode before you get to the end of forms-- none of which says--> HEY, THIS IS AN OBVIOUS FRAUD!

      You can discredit sellers, but sellers have options to restore their dignity if they want to do this-- although it's tough. PayPal can also interecede, as can buyer credit sources. Resources, except in the complaints department, are tilted towards buyers. But that doesn't mean that there are loads of phish attempts. You find them in amusing places, like when I tried to surf for an Apple notebook, and there were a hundred auctions for the same machine-- if you bought the story about getting it shipped from Italy.

    • The only real way this could be used to profit by a "criminal" in the classical sense, is to facilitate extortion. "Pay us off or we'll make your auction site worthless." However at that point you get into the problem faced by every extortion racket, hiding your tracks, both financialy, and your communications. Easy enough to do the latter, a lot harder to do the former, especially if you pick a big fish with muscle to push an investigation.

        Certainly difficult, but not impossible, evidenced by the fact that extortion racket still exists, as does the money laundering business. But I do agree with you that the difficulty is probably more or less directly proportional to the resources of the victim.

    I've never really understood why there's this belief that criminals have trouble being honest. Often, a criminal is only such because society labels them that way and thus dishonest. But in reality, many of them are very nice people performing honest business transactions (unregulated at that!) for their clients. Many drug dealers, prostitutes, pirates, hackers, etc are very honest people in the sense they aren't scamming their customers. They will provide great value to them in fact.

    Supporters of the free market can look to the very successful black market as an example of unregulated trade working well. Often in the black market, as this article eludes to, your reputation is everything. So there is no benefit in ripping someone off.
