As someone working at a bigtech co that has spent every single working day (and many weekends) since the launch of Mythos patching serious, company-ending type of security issues, these types of posts really irk me.

Public datasets of CVEs being underwhelming doesn't mean much if all of the issues are in private company codebases that will never get a CVE number assigned and will never get a fancy blog post. You're never going to hear about them, and the people working on them probably can't tell you about them, but that doesn't mean they don't exist.

We're all worried about OSS having security issues because of how widely used things like PHP or curl are... but the same can be said about email providers, document collaboration SaaSes, payment processors, etc that millions of companies depend. Those companies will never be in datasets like this, and they'll never publicly disclose how many issues they found.

Yeah I am much more worried about some critical vulnerability in, say, the controller logic for pumps at sewage treatment facilities vs. a sandbox break in Chrome (which will be patched well before the blog post...). The broad issue is that you can turn DeepSeek-v6-unhinged loose on an arbitrary IP and exploit ~everything that is not developed and actively maintained by a billion-dollar company

Agreed. My fairly obscure company got hit by something like this last weekend. What stood out was the speed: attackers found something small, used it to uncover something else, and pivoted to clever exploits for the new thing within minutes. It hit a dozen of our apps in parallel within the span of a day, from a rotating pool of residential proxies, Tor, GCP and Cloudflare IPs.

I'm fairly confident it was LLM-driven. The payloads and throwaway accounts had names like "PT59553 TEST IGNORE" and "PocCorp1659r2", and it adapted to error messages the way a person reading them would, just never sleeping. A non-tech company with 100x the surface area and much more valuable data could be in big trouble.

Of course I used LLMs for the defense too, and they were amazing at log forensics and fixes. The annoying part was when I asked Opus 5.5 for clear repro cases of exactly what the attackers did, I hit the cyber safeguards. Opus was trying to keep the exploits for my own bespoke applications away from me. It was happy to fix things of course, but I worry if it really can't 'think' about actual exploits, its fixes will be less informed.

the broad issue is actually that those are connected to the internet at all and there is no real enforcement or penalties for it

billion dollar companies are not exempt from this, in fact they tend to be the worst offenders

we've already had water treatment plants hacked and the amount of chlorine in the water changed. Florida ended up with dangerous amounts of lye being added to the water and was saved by an employee that noticed the change...I am worried, no airgaps to be found..

Just like the European freezers and refrigerators.
"should be" is doing a lot of work here.

Airgaps don't solve everything either. Stuxnet was successful at destroying air-gapped machines.

One example they use in the blog post is curl. Not maintained or developed by a billion dollar company.

I suspect open source projects are better off than proprietary software - they already have many eyes on them, whereas commercial software that’s not a prominent and profitable target (e.g. windows, ios) hasn’t had much attention until LLMs made attacking them significantly easier

The average enterprise software is swiss cheese. It seems the hacker news type that likes to post just doesn't realize how much business/enterprise software exists out there. An F100 company has thousands, maybe tens of thousands of applications that you've never heard of and never will unless you work for them. Industry has applications ran by relatively few people, but it's keeping processes that make the modern world work alive.

Worse is everyone is like "Well, this stuff is protected or air gaped". Yea, it's behind firewall, or even private networks commonly, but the moment you get inside that network you have tons of lateral movement and could cause unbelievable damage in minutes.

> I suspect open source projects are better off than proprietary software - they already have many eyes on them

This has been disproven by the sordid history of OpenSSL. It was open source, critical, and full of holes.

Directly? No. Indirectly? Yes. They are mostly funded by billion dollar companies.

Have you seen any patterns for the causes of the error you have seen? For example, more training for developers? Or maybe just systems were really very complex that led to bugs?
With code public many of the actively used and maintained open source projects have better code quality than proprietary or big MNC ones. Forget Mythos level models but even smaller models are able to find large number of issues in closed source tools in my example. One reason obviously is the peer review and quality checks by users/hackers/maintainers over the years.

They shouldn't. AI is great at some things and underwhelming at others, and it's never predictable if you're going to get the great response or the silly one and when you'll get it and over what topic. And you and the author combined are illustrating one scenario where that jaggedness shows up.

Possible you might be believing the LLM too much. It seems to flag so many “critical, company ending” security issues, the ones surviving any semblance of scrutiny I’d estimate at 0.5%.

Make sure you’re still thinking.

as a bystander not even working in the sector, your witnessing is exactly what I was worried for. if an agent is wily enough to defeat a security it should also be wily enough to cover its tracks, otherwise what's the point?
