US Chip Cards Are Being Compromised In the Millions (threatpost.com)

According to a study from Gemini Advisory, some 60 million U.S. cards were compromised in the past 12 months. "Of those, 93 percent were EMV chip-enabled," reports Threatpost. "Also, crucially, 75 percent, or 45.8 million, were records stolen from in-person transactions." From the report: These were likely compromised through card-skimming malware and point-of-sale (POS) breaches at establishments like retailers, hotels and restaurants, the likes of which continue to make headlines. Further results show that the U.S. leads the rest of the world in the total amount of compromised EMV payment cards by a massive 37.3 million records. In the past 12 months, about 15.9 million compromised non-U.S. payment cards were posted for sale on the underground, split between 11.3 million card-not-present (online transaction) records and 4.6 million card-present records, of which 4.3 million were EMV enabled. This means that the theft level of EMV-enabled card data in the U.S. is 868 percent higher than the rest of the world combined.

The reason for this state of affairs, according to Gemini, is the lack of U.S. merchant compliance -- too many of them still use the mag-stripe function at PoS terminals. Gemini also said that card-present data "is also collected via a more manual method by skimmer groups, who are utilizing custom made hardware known as 'shimmers' to record and exfiltrate data from ATMs and POS systems. The firm also found that while most large U.S. merchants have fully transitioned to EMV, gas pump terminals and small/medium size businesses are emerging as the main targets for cybercriminals going forward.

      If you can intercept the conversation between the EMV chip and the terminal, you can skim enough information to produce a counterfeit mag stripe that will work. That's actually a long-standing vulnerability in the EMV system.

      There was supposedly a fix which involved programming different ICCV codes on the chip and in the mag stripe, but that fix depends on the card provisioners to implement. This is typical of security debacles: a fundamental weakness in the system isn't really fixed by a band-aid that requires everyone to do the right thing.

      Not even half, maybe a quarter measure. The chips can not only be bypassed, but because America doesn't use chip-and-PIN, the chip can be used directly by anyone stealing your card.

      It is like putting a titanium deadbolt on your front door, and having an aluminum screen door on the back of the house, and also putting the deadbolt cylinder in backwards so the thumbturn is on the outside.

      The rest of the world did this right. Only America screwed it up so badly, and mostly because the people with the ability to fix it (that banks) have no incentive to do so. They just push the losses off onto the customer or the merchant.

      it was not magstripe, it was outright forgery. I don't believe they ever had my card, but I suspect the equifax (etc) break-ins were the cause of most of this.

      there is 'skimming' and 'shimming' but in my case, I don't think it was a copy of the card; I think they frauded the system some other way.

      one thing the bank told me: if these were magstripe transactions, we would have voided them out as soon as you reported them to us, but since they used MAGIC CHIPS, of course, those are trustable so we are rejecting your claim.

    Here's the thing -- by allowing the Russians to take over Eastern Europe in 1945, the US created that particular mess. The US should have stuck to their guns in 1945 and required truly free elections in all of the countries concerned. We had nuclear weapons. Stalin did not.

    This being said, the stereotype of Eastern Europe being a mecca for fraud, corruption, and nothing else, is a bit of an outdated trope.

    If the EMV functionalities are not fully deployed, the track 1 and track 2 data stolen from the chip transaction can be easily encoded by the fraudster onto any magnetic strip.

    So to get this straight, you get a plastic card, it supports both the newfangled way and the old-and-busted way (or else people would be up in arms that it wasn't compatible with 100% of readers). By the way, the new hotness is just the old version plus a transaction-unique cryptographic token. Now, when this is deployed, people figure out -- they skim the new way and then use it to create mag-stripe cards that can be used only at places that don't require a chip. But somehow this is a problem with the chip cards?

    Nooooo, it's a problem with places that don't require a chip. We've known since the 80s that you can copy a magnetic strip with a 2-tape boombox (seriously, it will work).

      Those merchants are having to pay for their lack of adoption. Based on Visa and Mastercard rules, if the merchant doesn't support chip cards, and there is a fraudulent transaction using the magnetic strip, the merchant is out the money. If the issuing bank doesn't provide a chip card, the bank is out the money. These incentives will talk more loudly than people preaching better security.

      A lot of the fraud was solved in the rest of the world by a simple change to the merchant banking rules: merchants may not take the card out of sight of the customer. If you want people to pay at the table in a restaurant, you come around with a wireless card reader. This removes 99% of the opportunities for skimming and it means that if a merchant does take the card away it's so unusual that the customer will likely remember it when they discover fraudulent transactions and can easily report the source. It's weird visiting the US and seeing that it's still standard to allow waiters to take the card away into a back room where they can make a clone and bring back the original.

    The headline is misleading. It is not the transactions by chip that are being compromised. The fact that a card swiped the old fashioned way happened to have a chip is moot - it is the same attack vector on the legacy magnetic strip.

    There must be significant expense involved for merchants to switch to the chip readers, as most of the POS now systems have chip readers, but some retailers don't support them. More than likely it is price gouging by the vendors that configure and manage the POS units.

    Finally, in my area, Lowes Home Improvement has the totally bizarre setup where if I want to use my bank card as a debit card (requiring PIN) I must swipe, and if I want to use it as credit card (requiring signature) I must insert it. However, it asks you AFTER you have inserted or swiped, so if you choose the wrong option then you have to remove or re-swipe the card. The local store has resorted to putting handwritten notes on the POS terminals advising which to do (insert or swipe) depending on whether you want credit or debit. That leads me to believe there is some recurring per-transaction cost using chip with debit.

    Whenever I travel to the US, one of the first things that I notice is different is the lax approach to card security. In most of Western Europe, pretty much every card transaction uses the chip. I can disable the mag-stripe on some of my cards (through the banks' online systems), and using magstripe anywhere increases the chance of a transaction being picked up by the banks' automated fraud detection systems. Then when you get to the US, you go into a restaurant, settle up by card with no signature and no pin, and then the restaurant can manipulate the transaction later to add whatever tip you wrote on the bill. Madness!

      Some bank ATM's rewrite the magstripe every time you use it with a different security code. They recommend you insert your card in their ATM's when you return from holiday, as if it was skimmed and they've update the security code since then, the fraud detection kicks in immediately when the skimmed card is used.

    sigh. I'd like to type in pages but I won't.

    long story short, I got a text from wells saying they thought something was 'up' with some purchases. I never check sms (I use email and ignore sms) but I later found that text and called wells to check if it was real. it was real and there were thousands of dollars of charges I didn't make. I never lost my card and it was never out of my posession.

    I called wells and we went thru the charges. I told them which were mine and which were unknown to me. I thought that was it and waited to hear back. weeks later, I get a letter in the mail from them saying that they 'investigated' it and since the card was never lost and it was a CHIP BASED CARD, it could NOT BE THEIR FAULT and I was told I had to pay the thousands of dollars of charges!

    I was shocked. I was a member of that bank for over 20 years (yeah, I know, I should have left years ago when wells first had issues reported against them).

    the weeks that they let it sit were weeks that evidence was starting to fade away (video 'tapes' being recycled at stores, etc). I think that was also part of wells' plan, to delay me and make me miss some deadlines.

    I forced them to re-open the 'closed' case and I filed a police report. I was not asked to at first, but when I went to the bank in person and made an issue of this, they asked that I make a formal police report, which I then did.

    get this: one week later, I get letters in the mail from the local court system. they caught 2 people and I was informed that sentencing was going to happen in 1 week and I was allowed to attend, if I wanted. (I suspect that the forged card had my name on it or receipts from stores had my name on it).

    here's the kicker: it took ALL OF THIS in order to convince my bank that it was not me. their line, all along was 'it was a chip card and it never left your possesion, in your own words, and chip cards are PERFECT, so pay up, it was you!'. that was their line and until I showed them court papers, they would not give in.

    tell everyone you know about this. the chip cards are less than useless in the US and banks are still putting their fingers in their ears and saying 'I cant hear you, its still your fault, pay up!'.

    their security system is at fault and yet they blame us.

    it took me MONTHS to get this all cleared out. did I get anything for my time? no. of course not.

    wells fargo can eat shit and die. anyone still with them should leave immediately. I was a 20+ year member and they threw me under the bus for a few thousand dollars. they don't deserve to have a single customer. please leave if you are with them.

    and be very careful with your 'chip' card. there's nothing secure about it. the thieves have it all worked out already ;(
