freitasm:Oriphix: First the CSR told you it was a security risk to update the CC information. Then she TOOK the CC number to make a payment? What'd the difference she got the CC details over the phone either way?
Last year there was a high profile case where a guy in the USA had his iPhone, Macbook, iPad all wiped out through iCloud through a bit of social engineering.
The person doing it couldn't directly change the password on iCloud, he needed the last four digits of a credit card number stored with Apple - he used Amazon to get that information:
Getting a credit card number is tricker, but it also relies on taking advantage of a company’s back-end systems. Phobia says that a partner performed this part of the hack, but described the technique to us, which we were able to verify via our own tech support phone calls. It’s remarkably easy — so easy that Wired was able to duplicate the exploit twice in minutes.First you call Amazon and tell them you are the account holder, and want to add a credit card number to the account. All you need is the name on the account, an associated e-mail address, and the billing address. Amazon then allows you to input a new credit card. (Wired used a bogus credit card number from a website that generates fake card numbers that conform with the industry’s published self-check algorithm.) Then you hang up.
Next you call back, and tell Amazon that you’ve lost access to your account. Upon providing a name, billing address, and the new credit card number you gave the company on the prior call, Amazon will allow you to add a new e-mail address to the account. From here, you go to the Amazon website, and send a password reset to the new e-mail account. This allows you to see all the credit cards on file for the account — not the complete numbers, just the last four digits. But, as we know, Apple only needs those last four digits. We asked Amazon to comment on its security policy, but didn’t have anything to share by press time.
Each company has different "security" and sometime they overlap, sometimes don't. When these don't overlap you can exploit it. What one company deems "private information" other companies don't. And that's when things can happen. Read the long version here.Satch: Monopolies don't need to provide efficient service.
In this case they are probably right in doing the way they are doing. Asking for the credit card information for payment is different than recording a credit card against an account, which can then be used for reset, etc.
My views (except when I am looking out their windows) are not those of my employer.
freitasm: Correct. A one off payment means that credit card is not associated with your account. A recurring payment means the credit card is recorded against your account, which also means someone could use the same trick used on Amazon to get to reset your account password, change details, etc by claiming "I know my credit card number in the account."
In another side of this there are some security obssessed companies such as Trade Me. It seems they (or their credit card processor) record the credit card information EVEN IF YOU UNCHECK the option to store the number. I know because I once tried to use my Amex to pay my Trade Me balance and their processor compained that I had already used two different credit cards in my account, even though I NEVER check the option to store that data.
nate: Just as bad, WorldxChange make you post/fax your credit card number to them if you want it saved.
No idea why.

Nety: I think the key point here is that by having this system it is not possible to have a cc number registered against your account via phone. This means that as in the scenario freitasm mentioned it is not possible to someone to get a cc number registered against your account that they can then use to "become" you. So yes it does explain why the selectively will allow cc. In one case it is used on the spot and not stored. In the other (debit authority) it is stored against you account and therefore could potentially be used to gain access to that account.

What's to stop some cretin from downloading the Sky CC authority form from their website, filling it in, sending it to Sky, then accessing your account via the method frietasm linked to? I fail to see how this is any more secure?
You can never have enough Volvos!
richms: card expiration is yet another thing that needs to be resolved with cards. Absurd that card revocation or expiration can stop a recurring billing.
