Interesting to note that Phreaking is still very much alive and kicking. Most of the hackers I know gave up on Phreaking once hacking became popular in their circles. To me, there will always be something more fascinating about the telephone infrastructure.
Does it count as phreaking if you own the infrastructure?

I'm surprised this surprises anyone. This is common in brick and mortar stores as well. If you're processing credit cards online, you should be using some sort of fraud detection, like Maxminds MinFraud or something like it.
Then what the heck are we paying visa for?
Tl;dr you are on your own!
Long ago I did some contract coding for a company that processed donations via credit card. To my amazement, we had to watch out for people trying to donate small amounts to the Red Cross. Why? Because people with a list of possibly-valid credit card numbers would use small donations to brand-name charities as a way of validating credit cards. It made me long for some sort of professional association that kept track…
Should that have really been your concern? If every company that processes cards has to be fraud detecting experts, then they CC system is totally broken.

>Some of these services cannot be dialed via some VOIP providers (like Google Talk) for that reason. I always knew this was the case, but I was never really bothered by it. Both the law (see intercarrier compensation[1]) and the subsequent ban make sense. However I've recently run it to a rash of people who I can't call because my carrier and Google Voice block their numbers. Each of them has a Puerto Rican area code…

Puerto Rico is territory of and subject to the jurisdiction of the United States.

As Harry Tuttle said, "We're all in it together." https://www.youtube.com/watch?v=xlCPkmb6cuY Which is why it pisses me off when a company deploys insecure software or hardware, claiming that network security is the customer's responsibility. So my home network should be reasonably secure, so that it doesn't become part of a bot net. Which means that I have to, or should, become at least knowledgeable enough to know…

Have you heard of the "It's Lenny" bot? https://www.reddit.com/r/itslenny/ It's meant to keep telemarketers on the phone and waste their time, but it sounds like someone was using something similar for international phone fraud.
Goldmine. I just listened to a call where Lenny put the telemarketer on hold for a 2nd time to quiet his ducks. It's amazing how getting telemarketers to repeat themselves for the fifth time to a bumbling old man really takes the optimism out of their voice.
That's all of them (if the marketer stays on long enough).

>If every company that processes cards has to be fraud detecting experts, then they CC system is totally broken. That is 100% the case, at least in the US, for card-not-present (online, phone, etc) transactions. The credit card companies have zero liability for fraud in those cases...the liability is 100% on the merchant seller. In fact, the CC companies collect a non-trivial chargeback fee, so they arguably profit f…
It's win-win either way for the credit card network.
the end of the story just made me smile :)
