An FBI Agent's 3 Years Undercover With Identity Thieves 196

snydeq writes "InfoWorld offers the inside story of how FBI Supervisory Special Agent J. Keith Mularski, aka Master Splynter, penetrated and took over DarkMarket.ws, the infamous underground carding board hacked by Max Butler and later transformed by Mularski into an FBI sting operation. The three-year tour sent Mularski deeper into the world of online computer fraud than any FBI agent before, resulting in 59 arrests and preventing an estimated $70 million in bank fraud before the FBI pulled the plug on the operation in October."

    From an article I read on Wired what seemed to have brought the downfall upon Butler was some of his associates got nabbed for trying to use stolen cards to buy expensive retail items and then fence them on Ebay for cash. Seems to me that old fashioned F**k-ups are the way these guys usually get taken down. Also from the article I read that corrupt retailers and waiters use portable card readers to steal all mag data on the card. How would you protect yourself against that kind of attack?

        Buy things at small retailers unlikely to have complicated security policies or good video surveillance. Use local criminals to do the deal for you, promising a cut if they are successful getting the item out of the store. Keep the purchases under $2,000.00

        Sell those things for cash on the street. Don't sell in the same area that you bought the items. Stick to big cities, as the police have way more to deal with than small-time theft. Once you get a big enough stash, use it to start a cash friendly business or find a way to get it to a trusted party in the third world and do the same thing.

        The object is to not piss one person off to the point where they dedicate themselves to finding you. As long as the victim has the credit card company to turn to for a refund, and the police don't think the fraud is connected, no one will even bother opening up a case number.

          I have a serious solution to that problem: learn how to cook. As in, learn how to cook SERIOUSLY GOOD food.

          I can spend more on raw ingredients for a single meal than it would cost to take my wife out to a fancy restaurant (not that I do often, just saying that I can), or I can make something amazing for cheaper. And girls dig guys who can cook! Most geeks should like cooking too because there's tons of science involved and most of us like to tinker and make things. Plus when you're done you've got the most amazing meal that, unless you live in New York or LA, can afford to eat at a fine dining restaurant and are lucky enough to get a reservation, you're not going to get eating out.

          My wife and I never eat out any more. We're in a mid-sized town and every time we eat out it's always disappointing. Over priced and something I could make way better at home.

          I recommend "Zingerman's Guide to Good Eating" as a starting point for anyone looking to get into cooking. It explains how to choose the best ingredients, gives you the history of food's as well, and has some simple recipes too.

      As long as we use credit cards, you and I can't protect ourselves. However, the credit card companies could. Using public key authentication via smartcard technology would make it easy to verify physical access to a credit card. Yet the only instance I can think of, of anyone trying to roll this out is American Express's Blue card. Even that was mostly ineffective as the smart card circuitry appears to go mostly unused.

        I'm still wondering why the various banks don't offer reloadable cards for their customers. Why wander around with your ENTIRE credit limit in your wallet?

        And for debit cards, your ENTIRE checking account balance.

        Instead, allow the user to transfer the amount that he thinks he will need to a secondary card. That way, if anything compromises that card, the MOST they can get is whatever he put on that card.

        As for online purchases, how about one-use card numbers? Just go to the bank site, put in how much you want to pay and the bank will give you a one use number for that amount. Then the maximum you lose if the online site is fake is that specific amount. They never get the real numbers to your real accounts.

It's money stored on your bank card, that you can reload at any terminal using your PIN. Purchases made using this system are quick, as they don't require you to enter the PIN nor sign the recipt upon payment.

          So it's pretty much like cash in that it's for small amounts (up to 125 Euros IIRC), there's no authentication, and if your card is stolen whatever e-money you had loa

            In Italy you can get reloadable Visa Electron cards from the post office. Lots of people use these exclusively for online purchases, since even if the card info gets stolen there isn't much that can be done with it.

            Since they can't make money by delivering mail any more, the post office has branched out into banking and mobile telephony, and operates an airline as well.

        • That's essentially what I do already. Why do you need thousands of dollars in your checking account to begin with? Why not just transfer over only what you need? I mean, I can understand doing that a couple years ago, but my bank doesn't even really have physical banks anymore. If you walk into the building they have a few computers open to their website, an ATM, and one teller off to the side to help with things like opening new accounts. That's it. Everything is done online. And they reimburse you for ATM

          For online purchases one-use card numbers already are available.

          Bank of America has them, it's called 'Shopsafe' and it's a free feature if you have a card with them. I've used it for every web purchase now for years and it works great. You set your limit & expiration date, generate a number and your set. Easy and it limits your exposure.

          (MBNA developed shopsafe and then Bank of America got it when they bought them out. Probably other companies have something similar)

        I think you're right here in the US. When I visited London last year, though, it seemed like every single person had chips in their cards. I felt like a Luddite asking the guy to actually swipe the magnetic strip on a card (and him having to try a couple times before it took), then go find a pen, sign it, then find a place to put the paper signature. Us old-fashioned Americans.

          I had an experience nearly identical to this in London when a shop clerk asking if we had a card with a chip in it to use. The friend I was with didn't even know what he was talking about. I explained things to her, and then told the clerk we didn't, but could wander off and find an ATM to use instead. He dug around some and found a card reader, but it was obvious he hadn't used it in a while.

          The problem with that system is that it protects the banks and not the customers. Before you could contest the signature: now all they have is a PIN, and there's no way of proving who typed it in. It would be better to use chip, PIN and signature, but people will usually choose convenience over security.

            I had to contest a cash withdrawl recently, and because the PIN was entered correctly the bank concluded that it was an authorized purchase and would not be covered. They treat the 4-digit PIN just as they treat a signature.

        Actually, Visa USA was big into trying to roll out smart cards as well. I used to work for a start-up company that had a loyalty application to be used on the smart card, though we never got out of the pilot phase (for Target most notably). Visa USA's big push was because of the increased security, and hoped that loyalty would be the killer app to get it out in the marketplace.

        It's coming to North America, but slowly. Mainly because it will be expensive, and only serves to protect the consumer.

        Contrast that with the UK banks that have implemented the "chip and pin", where the courts ruled that due to the PIN, they aren't responsible for theft. The banks practically orgasamed all over themselves to get it going.

        It still doesn't offer complete protection. You can take the UK card to Germany, where merchants have not implemented the PIN. Or you can still shop inside the UK; just damage the chip. The card will fallback into "swipe and sign" mode that is used for cards without a PIN (such as those visiting from America).

        Or, even with the chip and pin, all one needs to do is some shoulder surfing. Everyone covers their PIN at an ATM. In other situations, people aren't used to doing that (restaurant, etc). Once you've identified a PIN, pick the person's pocket.

        Or buy things online.

        Or steal a lot of cards, and attempt to brute-force the PIN.

        Or there's an interesting relay attack:

        Consider the following scenario: You go for lunch in a small restaurant in London, and pay using your chipcard at the end of the meal. What you don't know is that the waiter at the restaurant is corrupt. You ask for the bill, and the waiter goes off to fetch a handheld Chip and PIN machine that he brings over to you. Meanwhile, on the other side of town, his accomplice is loitering in a jeweller's store. The waiter sends an SMS message to his accomplice, who goes up to make a purchase. Just as you insert your card into the waiter's terminal, the accomplice puts a fake card into the jeweller's terminal. The waiter's sabotaged reader simply forwards all the traffic from your card wirelessly to the card in the reader at the jewellers, and pretends to ask you to pay for lunch. You enter the PIN, thinking you're paying for lunch, but in fact you're buying the crooks a diamond!

        • The real flaw with chip and pin is that we've known it was possible to extract keys from these things with targeted damage for about the last 15 years to my memory. I remember hearing about cracking "smartcards" in Science News sometime in middle school.

      He probably wants a new assignment that involves less time at a computer. Did you RTFA? He was spending 18 hours a day on his computer, and was online every day of the week. His relationship with his wife was strained because he had to be available on his computer as often as possible to avoid suspicion and to keep his credibility up. He had to report his vacations to the people he was trying to bust weeks ahead of time, to keep up that reputation. To me, that sounds like the sort of assignment that you only participate in once, if only to keep your heart healthy.
