"It remains unclear why so many major corporations persist in the belief that it is somehow acceptable to store so much sensitive customer data with so few security protections." It's because there are almost no consequences to them if they lose the customer data, beyond a day or two of bad press. If they faced significant fines, fines that get worse the more sensitive the data is, then they'd have an incentive to do…

No consequences, the cost can be great, and it can negatively impact productivity by introducing hurdles to legitimate uses. Those are immense pressures a soulless company will need to overcome to do the right thing.

At the scale of this kind of incompetent failure, no human being should be on board with the narrative that we should be blaming "criminals" for this If we don't hold companies accountable for keeping far more access and retention than should be legal, and securing their systems poorly, this situation will never get better

Who is the "we" here? And how should companies be held accountable?

It's very rare for someone at the highest level to be held to any kind of liability, and paying fines rarely, if ever, causes these too-big-to-fail corporations to materially impact them.

Strictly speaking about the US here.

Earlier quoted context omitted.

It seems from the article that AT&T uploaded data to a cloud service, protected by username and password, and someone obtained credentials or breached the cloud service. What does that have to do with 'underlay networks' and wow is that "the root cause of 99% of breaches"?

An attacker who gets username/pw still can't get on the overlay network (the overlay requires credentials which can't easily be stolen or compromised, e.g. a private key signed X.509 certificate). Yes, because 99% of attacks use the underlay network to access the target and exfiltrate the data. Said the other way, an attacker didn't physically walk into a Snowflake data center, console into the right server, and walk…

That sounds more like the lack of certificate-based authentication (or some other stronger authentication method) was the problem, not the lack of a private overlay network.

After all, plenty of private overlay networks use simple username/password auth or no auth at all.

Why did it take them over a year and a half to disclose this?

Something, something, national security?

The DOJ approved two 1-month "delay periods", first in May, then in June, as part of the criminal investigation. We found that out earlier this morning, see earlier discussion.

"still-unfolding data breach involving more than 160 customers of the cloud data provider Snowflake.'

So what is Snowflake normally doing with all that AT&T data? Redistributing it to "marketing partners"? Apparently. Snowflake's mission statement, from their web site:

"Our mission is to break down data silos, overcome complexity and enable secure data collaboration between publishers, advertisers and the essential technologies that support them."

So this was not, apparently, a break-in to the operational side of AT&T. Someone unauthorized got hold of data they were already selling to marketers. Is that correct?

did they just enumerate an open web endpoint for it or something?

API based credentials are just username + password in this context, nothing else seems to be restricting access to data. So if your Snowflake tenant isn't enforcing IP restriction to limit source auth attempts, those creds can be used to pull the data from any source IP.

Even then, you'll still have an HTTP 403 response layer filtering those auth attempts based on IP... where we can assume these failed to implement it.

So far between TechCrunch, Wired, and other reporting it seems most claim creds get owned, sold, then used against under-restrictive Snowflake tenants which are exposed by default.

i.e; https://epa06486.snowflakecomputing.com/console/login#/ here's someone's tenant, if you were able to go buy some creds for it, should walk right in.

Needs to be at the level of enforcement by regulatory agencies, large scale lawsuits backed by state governments, and maybe even congressional action

These companies have scale as their moat and that's called a monopoly. We need to be aggressively pursuing corporate malfeasance, closing loopholes, and breaking up companies. In my ideal world the entire doctrine of the "corporate veil" would be overturned, but that seems unlikely to happen without drastic upheaval. Antitrust action and large-scale suits can happen and to some degree those wheels are already in motion, but it would help a lot to stop buying this bullshit about how we should think of this as a "crime" for which we should uniquely blame hackers. These megacorps want to pretend that they and their customers are in solidarity as victims of the hackers. In reality, these companies get hit with essentially none of the consequences, and their practices are most of the relevant causal factors. A better model would be that the customers (and often non-customers on whom they collect data without even the figleaf of manufactured consent) are victims of the companies and the hackers
