Attacking Criminal Networks On the Internet

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. If we can find such a site...why don't we just find out whose using it and arrest them? Is this some new take on crime, that instead of arresting criminals we should discredit them? What's the plan?

      Extortion also only really works in cases where the appearance of normalcy is more important to other trust relationships of the victim than whatever payment the extorter requires. That, or they have no recourse to the local law enforcement authorities for some reason.

      From what I've heard, banks often get extorted successfully by Internet-based rings. They pay up, and shut up, because it's cheaper than the huge hit to the trust of their depositors in the institution. Look at what happened to Northern Rock when they stood up and did the right thing to ensure their depositors were safe by going to the Bank of England. The first run on an English bank in a century.

      An auction site like eBay doesn't need my trust nearly as much. They don't have my credit card number (unless I use PayPal, but that's not a requirement to use eBay). I don't think I even had to put in an address to set up an eBay account to merely buy stuff. The only trust I need is in the particular seller. Now I'd be the first to admit that your average eBay seller is not toward the high end of the trustworthyness scale, and that the feedback system is abusable, but you're working from a pretty low baseline in any case. And what exactly does eBay have to lose if they broadcast to the world that some dastardly group threatened to make people think that eBay sellers are fraudsters?

      Now your black market, that's a lot more like a bank in terms of amount of trust required. A bad deal on a black market doesn't mean you call up PayPal/eBay/bank and tell them that that bastard that promised you 100k of fresh credit card details ripped you, and you want your money back like the victim of a bad deal on a legal marketplace can. Hell, if you're an intelligent person doing business in a place like this, you know damn well that your buyer or seller might be a cop. A wasp doesn't complain too loudly when it gets stung. It's easier, and safer, to find another patch than try to rebuild trust in a compromised location. Not that it's asy, you need to rebuild trust in this new marketplace, which a determined poisoning scheme can probably easily deal with, so you'd theretically be forced into a more personal marketplace, where personal recommendation is required in order to be able to buy. Harder to crack, but WAY harder to use, and it keeps the cost of entry high enough to discourage all but the most determined criminal wannabes.

  9. The bad guys are already phishing on eBay by postbigbang · · Score: 4, Informative

    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.

  11. Difference between law enforcement and warfare by R2.0 · · Score: 2, Insightful

    Drug interdiction efforts in this country have been law enforcement based - interdict, arrest, trial, imprisonment. Intelligence is limited to that which can be used in court for trial - all else is forbidden.

    The techniques referenced in the article are more in the style of warfare, where the objective isn't to arrest a lawbreaker, but defeat an enemy. Different rules apply. For instance, if an anonymous source gives you the key for Botnet A, you don't have to worry about gathering more evidence to be able to convict - just shut the sucker down, or poison it to turn on it's creators, etc.

    The confusion between law enforcement and warfare is going to get worse and uglier as time goes on. And I'm not advocating using military thinking domestically on drug trafficking in the US - it doesn't work real well in foreign countries, and I think most drug laws themselves are misguided. But on botnets and international computer crimes? Oh yeah - it's definitely war.

  14. Wht can't criminals be "honest"? by nate+nice · · Score: 4, Interesting

    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.

    I've worked with many "honest", good people in my black market transactions.
