“It feels like we hit an inflection point in the last week or so. Kind of a large tidal wave to crash on the coast, but likely not the tsunami yet.”

Basic security hygiene and traditional defensive practices remain sufficient; LLM-enabled shortcuts are the real problem, not inherent vulnerability.

“Its really not that hard to secure your servers, especially if your not a high value target… I dont think my security posture is all that much different than it was last year.”

Commenter references advanced AI release as precursor to widespread hacking capability
A commenter referenced the release of 'mythos' as a marker point, estimating a six-month window before similar AI hacking capabilities become operational in the wild.
“When mythos was released - I guesstimated that we had 6 months until hackers had similar enough capabilities that we would start to see real problems in the wild.”

This isn't Linode getting attacked, it is telling customers that this zero click RCE CVE is pretty serious. You should patch ASAP.Did you know that GO defaults to listening on TCP connections with MPTCP, so anyone running GO programs listening on the internet (Caddy, traffic, etc) and are on an unpatched kernel now have a way to from attackers to…

Commenter attributes security gaps to LLM-driven shortcutting in development practices
A commenter disputed the necessity of sophisticated security measures, arguing that LLMs may be worsening security posture by enabling developers to skip foundational learning steps.
“If anything llms are making security worse because there's more people offloading their thinking on llms, or people that skipped some steps in their learning journey because they just ask the llm to do everything.”

Its really not that hard to secure your servers, especially if your not a high value target. If you are a high value target, you should have security professionals on staff.I dont think my security posture is all that much different than it was last year. Use a Secret Manager and or encryption, have backups, strong firewall rules, use canaries of…

Commenter forecasts AI-powered attacks escalating across infrastructure tiers
A Hacker News commenter predicted a timeline of AI-assisted attacks moving from cryptocurrency in July to infrastructure and SaaS now, with traditional banking and small business targets expected by December.
“Now the AI powered attacks are hitting infra and SaaS. Next (~December), it will hit classic infrastructure, banks, small businesses, etc.”

All companies should at this point invest a lot of money into defensive AI. In ~July the AI hit crypto and bitcoin, where it's the easiest to extract the most money. Now the AI powered attacks are hitting infra and SaaS. Next (~December), it will hit classic infrastructure, banks, small businesses, etc. By mid next year, we will be over this hump…

This reads to me that nothing has happened and they are just trying to patch stuff? Right?

It feels like we hit an inflection point in the last week or so. Kind of a large tidal wave to crash on the coast, but likely not the tsunami yet. I hope.If you are running services and don't yet have an easy way to react to these things with swift process defined, I hope you don't like to sleep.

Wow, that isn't clear. Is there an incident, or did they just become aware about MPTCP vuln? Details on the mptcp are also pretty scarce as well right?

@dang I would encourage you to really think about having security incident as a new HN tag. The wording can be better though.

What if the "inflection point" is just all of the low-hanging fruit that can be detected by agentic vulnerability scanning? If the low-hanging CVEs get patched we might not see a tsunami.

Why was the previous discussion of this flagged? https://news.ycombinator.com/item?id=50299182 Is our new policy to stick our heads in the sand and pretend that CVEs don't exist? Because I'm not getting behind that!

Anybody recommend a CVE alert self-hosted app? E.G. I specify my software, OS’s, and versions and when a matching CVE is created I get an alert. Don’t want enterprise security products.

Anyone have any thoughts on what happens when banks/brokerages start getting hit in earnest? Think it's prudent to split single brokerage portfolios across multiple? Or do they have enough speed bumps in their procedures that they're not quite so vulnerable to major losses?

I've lived to see the day when half of the Hacker News front page is about hacks. What a time to be alive.
