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.

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.
we lost thousands in a couple weeks due to fraud and had to up our game in detecting fraud and now are overzellous in rejecting cards due to fraud
I have a related story. I was in North America, looking for an apartment in Australia. At the time I'd buy phone cards for long distance calls, and they'd always work fine. So, I used the phone card, and tried to call someone about an apartment that looked great. According to the advertisement, it was a woman that owned the apartment and she had an extra bedroom she was renting. I called, and a man answered. It went…
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.
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…
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?

Businesses with high fraud numbers will get axed by Visa.

Definitely. There's also the same sort of issue with gazelles and cheetahs. Both are fast, but for the cheetah to get its dinner, it only has to be faster than the slowest gazelle. I'm sure some of the phone companies are reasonably fraud-resistant, but securing a whole industry is harder.
Well, in that case the companies just have to not be the slowest gazelle, right? That doesn't seem like much effort involved, so the problem is probably in knowing what the other companies are doing so you're not the mark.
The companies themselves have little incentive to change things if it costs them money to do so and there's limited downside for doing nothing.
The "free" phone conference service work in a somewhat similar way. There's a fee charged for long distance call even in the US/Canada. The fee is low enough that most people now get free long distance. The free phone conference services are terminated at tiny little telcos that charge a much higher than normal fee for a north american long distance and the fee is split between the conference service operator and the…
>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…
