So if . . . the file was encrypted encryption were applied end-to-end in the transport layer the recipient's identification were ensured . . . would such an exchange be PCI compliant?

For mag stripe, as answered by Thomas. But note that most countries implement EMV differently and may allow mag stripe purchase if the chip fails to read. The actual chip area of an IC card is very small. (If you look carefully at a well-used card, you may be able to see the location of the actual chip.) If the cut is not right through the chip, the chip ...

I'm quite sure you will be able to recover "some data" from the magnet stripe - likely even all the data that's on there. However, you won't be able to withdraw any cash with a copy of that stripe because nowadays use the information on the chip, which is much safer as it is much harder - close to impossible, I would guess - to copy that. The only thing you ...

You'll just have to follow your PCI procedures. You'll have to create a change that allows the statsd server to exist. A manager will have to review/ok the change. It will cause a few dependent changes and activities: add a new statsd server to the DMZ (network change, system change, system hardening, configuration standards) add the statsd service and ...

The quote is short, but I think the author is trying to say that the router wasn't about ATM skimming, and not even about the ATM itself. It was a MITM for customers who used WiFi (personal devices). In this case, it was just a rogue AP that presented a fake certificate to users, and the users (or their poorly written apps) had to accept the fake ...

IANAQSA! That data doesn't put you in scope, but you're probably in scope anyway, but dint of whatever relationship you're in that gets you access to that non-scoped data. To quote PCI-DSS 3.2 (emphasis as per source): The primary account number is the defining factor for cardholder data. If cardholder name, service code, and/or expiration date are ...

CVV is calculated: To calculate a 3-digit CVV, the CVV algorithm requires a Primary Account Number (PAN), a 4-digit Expiration Date, a 3-digit Service Code, and a pair of DES keys (CVKs). Source: http://www.darkcoding.net/credit-card/cvv-numbers/ This calculation can only be done by the card issuer due to the use of secret CVK, which is known ...

Credit card providers manage risk. They seek to find a line between convenience for a client and reducing fraud. The best or most secure way of working might not be a convenient one. Convenience is important as users might choose another credit card aquirer if they are unhappy. Second of all it offloads part of the risk to the merchant, meaning if fraud ...

Another solution which guarantees the peace of mind is a prepaied "credit" card. This way you can never be charged more than you've put in. Depending on the card, you may also save foreign exchange fees. Both Mastercard and visa issues these, but they're probably easier to get from third-party organisations.

Ask your credit card provider for a one-time card number. Or get a new account with a low limit. Put the credit card number (and maybe a short random string) in a plain text file. 7zip this file with AES encryption. Email the hotel with this file as an attachment. Phone them and tell them the password to decrypt the file. (You might have to do a bit of ...

It's quite common for hotels to pre authorise payment using your card details. This is to prove you are who you say you are and check you have sufficient funds for your stay. Although emailing may not be the safest way of sending your credit card details. Perhaps a phone call would be better but still not "secure" What I would suggest is that you opt to ...

This entire situation sounds wrong. The typical flow of a user purchase or transaction in this kind of environment would be as follows: Vendor site calls a payment provider API, passing details of the transaction: vendor ID, product name and identifier, cost breakdown, customer name and address if known, and sometimes other technical information such as ...
