According to the article, this applies mostly or only to Delta Dental of California.

Slightly OT: Delta Dental was the company that Costco used to sell Dental Insurance through. (unfortunately, that partnership has ended with no replacement.)

Careington and Thrive both offer overlapping discount plans that (especially combined) can more than offset the much higher monthly (not low annual) prices that Delta Dental is now charging, especially for a family.

When I ask my non-techie friends about stuff like this, they really don't care anymore unless they actually get hacked, scammed, etc. It happens so often that there's now "breach fatigue". Meaning little pressure on companies to do better.

Even as a tech person, I am indifferent. I’ve adapted to a world where cards get stolen, so I never use debit, review my statements, and have spending notifications turned on for my phone. I have the apps so I can instantly lock my card. I have already learned to live in a financial castle. It is obviously not great, but an additional breach has little marginal impact on my life.

The real question is why online credit card payments still involve using the whole card number, as opposed to some message signed by the card's private key authorizing certain spending limits for a retailer.

Surely the data breaches we hear about are the tip of the iceberg? Just think of what needs to happen after a hack for you to hear about it: - someone at the company needs to be aware it has happened. - they need to accurately identify what was accessed. - they need to disclose that this has happened. - it needs to be visible enough that it gets picked up and talked about. Each step of that funnel must have some drop…

Yes, i'm pretty sure no more than 5% of breches and leaks gets public press.

There's so many internal company filters a breach has to go through to become public all the way from some engineer messing up and "just closing the terminal" with a beating heart hoping no one will notice - to a long chain of managers who has to send the message upwards, then the leadership approving public disclosure, all with negative pressure to not disclose because of career, stress, extra work, penalties, all the way to stakeholder value.

> who had their names, financial account numbers, and credit/debit card numbers, including security codes, exposed. Delta Dental should be rightly and truly f'd for that one. Storing security codes at all is totally forbidden by PCI rules. Delta Dental should have their ability to process credit cards completely revoked for this egregious breach.

> Storing security codes at all is totally forbidden by PCI rules. It's kind of silly though. They are no more "secret" than your credit card number itself or expiration date. Once you give it out once or hand your credit card to literally anyone, it's out. Now instead of acquiring N numbers, the hacker needs to acquire N+3 (or N+4) numbers. Our payment system needs something like: struct { string credit_card_number;…

> Now instead of acquiring N numbers, the hacker needs to acquire N+3 (or N+4) numbers

This seems almost as reductive as suggesting my mechanic should keep her customers' key(k) in their cars(c) in her parking lot because instead of just acquiring c, now the thieves just need to acquiring c+k.

If we were talking about 3 extra digits on the card number, that would be one thing. But we're talking about a separate authentication factor, which seems pretty worthwhile to me. Getting that info isn't exactly a snap if you don't just find it laying around-- it's not like you can brute force it. I'd be pretty astonished if a credit card company didn't cancel someone's credit card if someone was tried a handful of transactions with random security codes, let alone enough to guess one number in a thousand.

Sure, there are undoubtedly better ways to handle these transactions, but lacking magic wands to change a giant dinosaur of an industry that should have wanted to change on its own, this is a prudent policy-based strategy to mitigate harm. Whether or not you sweat these breaches is a good way to gauge your own processes, but it's not a useful way to gauge industry-wide processes.

It's not really another factor in the sense of the three types of factors: Something you know, something you have, something you are. It's just more digits of "something you know" so it's the same factor. It's why 2-factor auth isn't just 2 separate passwords.

Well thankfully point #3 is mandatory in places with laws such as the GDPR or California or Brazil's equivalents which mandate disclosure to impacted users and publicly.

Murder is similarly forbidden. Still happens.

They knew about the breach June 1, confirmed June 6, but the information is only made public after almost five months, November 27? (After a "second, more lengthy investigation".) This is better than nothing, but it seems absurd.

It is absurd, and it violates the mandatory timely notification laws which are in place in many states, including Washington.

Umpqua bank was also affected by MoveIt by way of one of their fintech vendors (FIS), they didn't even bother to notify my state's AG, as required by law, nor did they provide timely or accurate notifications.

Maybe companies feel a diffusion of responsibility when there are so many others affected.

Online retailers almost surely do better by allowing easy use of credit cards by even the least technical 5% of Americans than they would from a lower fraud system that required a moderate or higher level of technical acumen to operate.

Suppose I'm at a computer ready to buy a PS5 on BestBuy's site. What's the complexity now vs under a proposed private-key system? What's the loss in conversion rate on the latter?

It’s lamentable that any of this information still has value to fraudsters. Once it became clear that companies cannot safely control this data, it should have been stripped of any value by having some security token under user control provide the actual payment authorization.
