Hacker Demos Android App That Can Wirelessly Steal And Use Credit Cards’ Data

How NFC phones can steal your credit card info.

    Eddie Lee’s Android phone, displaying data it has wirelessly read from his credit card. I’ve blocked… the credit card number on the phone’s screen in orange. The symbol of nested arcs on the card shows that it one of the 100 million RFID-enabled cards in circulation.

    Smartphone payment systems like Google Wallet give Android users the futuristic ability to use their phones to make payments with their credit cards. Research Eddie Lee has taken that trick a step further: Using an Android phone to make payments from a credit card that belongs to an unwitting stranger.

    In a talk at the Defcon hacker conference in Las Vegas Friday, Lee demonstrated an Android software tool called NFCProxy that’s capable of both reading and “replaying” data from contactless credit cards–any of the common payment cards with embedded RFID chips that allow payments at retail outlets’ wireless point-of-sale devices like these. undefined

    After using a Nexus S phone to read his own contactless Visa card onstage at Defcon, he then used his tool to relay the data a moment later to a point-of-sale device, where it was accepted as a payment. “Ive just skimmed, abused and spent someones credit card within a couple minutes. Its really simple,” he told the crowd.

    Preventing Credit Card Skimming

    Skimming as a scam has endured for so long because it’s so often successful. Try these tips for foiling card skimmers:

    • Dont use free-standing POS terminals in badly lit or deserted areas. These are the most likely targets for skimmer action.

    • Deal directly with a teller or cashier when exchanging money. ATMs and other kiosks may be convenient, but you reduce your likelihood of being skimmed by avoiding them where possible.

    • Be on the lookout for damaged card readers. Any evidence of tampering should be seen as suggesting a fraudster may be at work.

    Only Use Secure Websites

    According to the Federal Bureau of Investigation , its crucial to avoid entering your credit card numbers and personal information on unsecured websites. Sometimes a tiny icon of a padlock appears to symbolize a higher level of security to transmit data, according to the bureaus site. This icon is not a guarantee of a secure site but provides some assurance.

    Hacking Nfc Via An App:

    Once we have read the key or fob we want, we can store all of the information onto a file. We can then use this information and write it back onto an empty card, essentially cloning the original or fob. Figure 5 below shows the Write Sector portion of the app, in which you can write individual sectors or write all of them. The important sector to keep in mind is sector 0 as it is what contains the UID and manufacturer’s data, basically if you copy sector 0 to another fob then youve made a copy.

    Skimming Credit/debit Card Information At Point

    While this scam has been around for several years, skimming is still a common method of credit card fraud. Skimming occurs at point of sale systems where debit and credit cards are used to make transactions, such as ATMs, gas pumps, and cash registers. More often than not, skimming is pulled off during legitimate transactions.

    One example of skimming occurs when thieves use a “universal key” to open gas pumps and embed a device that captures card numbers. They also position a pinhole camera nearby that records the pin numbers. Fake cards are then encoded with the information and fiscal havoc ensues.

    How do skim artists do this without getting caught? Sometimes its an inside job, orchestrated by an employee of the institution. Other times it is just good scouting crooks pick stations that dont have adequate camera surveillance. And any of those other instances in between, its the devils work. Seriously…

    How To Protect Yourself Against Nfc Hacks

    The most effective way to secure against NFC vulnerabilities is simply not to use NFC at all. However, if you want to use functions like contactless payments, then there are steps you can take to make it more secure.

    Compartmentalize your sensitive accounts. If you use your NFC device for, say, quickly making payments through Google Wallet, then one way to stay safe is to have a separate account just for NFC. That way, if your phone is ever compromised and your Google Wallet information is stolen, it will be the dummy account thatâs stolen rather than your main account.

    Turn off NFC when you arenât using it. This prevents accidental bumps from delivering unwanted programs and malware to your device. You may not think your phone gets within bump-range of many devices throughout the day. But youâd be surprised, especially if you find yourself in crowds a lot.

    Routinely check your device for malware, especially after youâve used NFC. It may or may not be possible to fully prevent NFC hacks. But if you catch them before they do much damage, that will be better than not catching them at all. If you find anything suspicious, change your important passwords and security credentials right away.

    How Widespread Is Contactless Card Fraud

    Steal RFID Credit Debit ATM Card Data with RFID/NFC App. Travel Safety Tip!

    It may seem like contactless technology allows fraudsters an easy way to access your money without a PIN. Assuming you take precautions to protect your card, the chances of it happening to you are reduced â however, consumers are right to be vigilant as cases of contactless card fraud doubled in 2018.

    Because contactless technology currently limits the value of purchases, the total potential value of fraud involving these cards is reduced. Thieves are always looking for big payouts, which are limited by contactless fraud.

    However, there’s also been recent research that shows that the £30 maximum spend on contactless cards can be bypassed. Researchers have found that the flaws in the payments system for some contactless cards could potentially allow criminals to steal hundreds of pounds in a single transaction.

    The hack the researchers used to break the £30 limit uses a device which intercepts the signals between the card and the card reader. It then simultaneously âtells’ the card that no verification is needed and the card reader that verification has been provided.

    Another purported method that fraudsters use is to actually process payments by standing near someone on a train or in another crowded public place and reading their contactless card through their clothes. However, according to Which?, there’s little evidences that this type of fraud is common.

    History Of Card Frauds

    There are lot of ways your card details can be stolen. Skimming tools like these steal data from the magnetic stripe of your card. Then there are portable devices like a mini POS that can handle contactless payment, which can be abused by a rouge actor like for example. Knowing this possible abuse, most POS machines offered to merchants have a limit on how much you can pay via contactless mode on a single tap like an upper limit of 100$ in some countries. For transaction above these limits, you might have to insert the card into the POS machine and manually enter the pin. The data captured from the card via this method will not have the static CVV/CVC that’s printed behind most cards. For an attacker, your Card number, Expiry date and CVV are the most valuable information along with Name/ZIP code in some countries. We will see how one can steal these information with an NFC enabled android phone in the coming section.

    Nfc Isn’t Perfectly Secure

    So does that mean you don’t have to worry about your NFC devices being hacked?

    Unfortunately not. NFC is more secure than other types of RFID, but it’s not perfect. It was designed to be a connection of convenience, not security. NFC requires you to bump, tap, or swipe an NFC-capable device like your phone against an NFC-capable reader like another phone. As long as both devices are NFC-capable and that they are within the NFC wireless range, the connection is valid.

    As far as the NFC protocol is concerned, the close distance is all thatâs necessary for a valid transfer.

    Can you see the weakness? No password or credential requirements! NFC connections are established automatically and do not require any form of login or password entry in the way that Wi-Fi does. This has the potential for some real problems since anyone can establish an NFC connection with your device as long as they get close enough.

    Imagine if you bumped up against a virus-infected NFC device? It would only take one bump for you to catch it.

    NFC can be made secure at the application layer by implementing secure channels or by requiring credentials, but NFC as a protocol itself is not secure at all. And despite the close-proximity requirements for an NFC connection to trigger, unwanted bumps do occur. Sometimes, even a well-intentioned bump can result in a disaster.

    How Money Can Be Stolen From Contactless Rfid And Nfc Cards

    Recently, a fundamentally improved version of money theft has been discovered. A new method of stealing money from cards equipped with PayWave and PayPass technologies. Criminals intercept the signals from such bank cards out of the air using hand-made readers.

    Plastic cards with contactless RFID chips can be used only by attaching them to a PoS bank terminal. In this case, such cards in a PoS terminal are not swiped and not inserted.

    There are methods now of money withdrawal from credit cards using the latest smartphone models, with a modification, a kind of RFID technology the NFC device. To withdraw funds from the card, hackers just need to know the full card number and a month/a year of the end of service.

    The cards of the MasterCard international system are equipped with PayPass chips, and the cards of the Visa payment system are equipped with chips with the name of PayWave. At the same time, both companies allow using their contactless technologies both on magnetic stripe cards and on newer cards with a square chip.

    The convenience of using MasterCard-PayPass and Visa-PayWave systems is to simplify and speed up payments in stores. When making payments for small amounts with the cards with RFID chips, there is no need to sign on the cash receipt or enter your PIN-code into the PoS terminal.

    To read the payment data, the fraudster will only need to have the reader approximately ten centimeters near the victims card.

      Myth #: I Could Accidentally Pay Another Customers Bill Or Make Several Consecutive Payments

      Payment terminals are designed to prevent payments being made for the same transaction twice, minimizing the risk of being charged multiple times, according to Jamie Topolski, director of payment card product strategy and output solutions at Fiserv.

      And if a terminal detects multiple cards, some will request that only one card be presented, or the transaction might be voided to prevent double charging, he added.

      The fears of accidentally paying another customers bill are also unfounded because the card must be placed within a very short distance of the payment terminal to be read, Topolski said.See related: Contactless cards: How they work
