how is this sort of stuff not at least encrypted at rest?

Encryption at rest does nothing to prevent online access to data. It's only useful if you leave your storage cabinet standing on the side of the road.

Your laptop backup could be encrypted. New problem: where to out the keys. Maybe another storage account with different access controls.

A number of replies here are noting (correctly) how this doesn't have much to do with AI (despite some sentences in this article kind of implicating it; the title doesn't really, fwiw) and is more of an issue with cloud providers, confusing ways in which security tokens apply to data being shared publicly, and dealing with big data downloads (which isn't terribly new)... ...but one notable way in which it does implic…

Occasionally, I’ll talk to someone suggesting a dynamically typed language (or stringly-typed java) for a very large scale (in developer count) security or mission critical application.

This incident is a good one to point back to.

On a lighter note - I saw a chat message that started with "Hey dude! How is it going". I'm disappointed that the response was not https://nohello.net/en/ .

This is quite funny for me because at first I didn't understand what the problem is.

In German, if you ask this question, it is expected that your question is genuine and you can expect an answer (Although usually people don't use this opportunity to unload there emotional package, but it can happen!)

Whereas in Englisch you assume this is just a hello and nothing more.

Would be insane if the GPT4 model is in there somewhere (as its served by Azure).

Also imagine all such exposed data sources including those that are not yet discovered... are crawled and trained on by GPT5.

Meanwhile a big enterprise provider like MS suffers a bigger leak and exposes MS Teams/ OneDrive / SharePoint data of all its North America customers say.

Boom we have GPT model that can autonomously run whole businesses.

Earlier quoted context omitted.

Pentests where people actually get out of bed to do stuff (read code, read API docs etc) and then try to really hack your system are rare. Pentests where people go through the motions, send you report with a few unimportant bits highlit while patting you on the back for your exemplary security so you can check the box on whatever audit you're going through are common.

Yep, most pentests go through the OWASP list and call it done.

The problem is that is what most companies want. They don't want to spend the money nor get the feedback beyond "Best case standards". It's a calculated risk.

Part of me thought "this is fine as very few could actually download 38TB". But that's not true as it's just so cheap to spin up a machine and some storage on a Cloud provider and deal with it later. It's also not true as I've got a 1Gbps internet connection and 112TB usable in my local NAS. All of a sudden (over a decade) all the numbers got big and massive data exfiltration just looks to be trivial. I mean, obvious…

How do you have your NAS configured? The more specifics, the better; I’ve wanted one. Do you worry about failure? In your hardware life I mean, not your personal life.

I use a Ubuntu raspberry pi with a cheap usb3 jbod array from Amazon that can hold 5 HDD. I use zfs on it in raidz1. It’s absurdly cheap, can serve about 80 Mb/s on a 1 gbps link, and is entirely sufficient for local backup. I don’t do any offsite. Set up to back up time machine, windows, and zrepl. Runs other services on the pi as well for the home network.

It’s so easy to set up an Ubuntu image that I control completely and I would rather do that than run some questionable 3rd party NAS solution and excluding disks costs about $130.

The article tries to play up the AI angle, but this was a pretty standard misconfiguration of a storage token. This kind of thing happens shockingly often, and it’s why frequent pentests are important.

Let me tell you about the laptop connected to our network with a cellular antenna we found in a locked filing cabinet after getting a much-delayed forced-door alert. This, after some social engineering attempts that displayed unnerving familiarity with employees and a lot of virtual doorknob-rattling.

They may be rare, but "real" pentests are still a thing.

> it’s why frequent pentests are important. Unfortunately a lot of pen testing services have devolved into "We know you need a report for SOC 2, but don't worry, we can do some light security testing and generate a report for you in a few days and you'll be able to check the box for compliance" Which is guess is better than nothing. If anyone works at a company that does pen tests for compliance purposes, I'd recomme…

Narrowly scoped tests designed for specific compliance requirements are fine. They lower the barrier to entry to some degree for even getting testing and still, or often enough, return viable results. There's also SAAS companies that have emerged that effectively run a scripted analysis of cloud resources. The two together are more economical and still accomplish the goals that having compliance in the first place sets out.

When I was consulting architecture and code review were separate services with a very different rate from pentesting. Similar goals but far more expensive.
