Both the defense is weaker due to LLMs and attacks become stronger and cheaper. Bad combination for the rest of us.
Are you claiming that LLMs are better at offensive security than defensive security? Or somehow that the offensive actors have access to better LLMs than people using them to defend? Otherwise it'd seem like the playing field just went up for both sides, unless one is famously lagging behind because no like to pay for better security? But that's also nothing new.
Computer security is asymmetric. Attacking is easier than defending. Attackers need to find one hole in the security. Defenders need to patch every hole.
I would also imagine bad actors are in the majority, and so we're seeing restrictions on models like Mythos in an attempt to balance the field a bit.
I don't know what's sadder: that people are doing that on HN, or that it's clearly working....
If someone really knew what they were doing and had bad intentions, I fear we would never find out.
The person using Claude to find the exploit clearly has a paper trail, so therefore they do not exploit. They sell the exploit to someone else and this is a profitable venture - not a crime. The person that has to disintermediate liability from actually exploiting, does not use the found data, they just sell the data - not a crime - instead of expand the liability surface and anonymity leaking by using the data. In fact they may even just leave the hole in the system open for someone else to exfiltrate. The person that steals from people with the found data, they don't just drop the money in their bank account, they hire mules in "work from home" jobs to have them use their own banking credentials themselves to make accounts to launder or convert the money exploited back to crypto exchanges and onchain.
This supply chain is pretty robust, might as well see what the market values it at, as shares.
The whole "article" is AI generated and insufferable. Do prompters like this one expect us to verify each slop assertion (repeated 10 times on average) ourselves?

On one side, Daniel Stenberg ran the gated Anthropic frontier model against curl on May 11. Five "confirmed" findings, one low-severity CVE after triage. His words: "the big hype around this model so far was primarily marketing." Stenberg is not a guy who hedges, and curl is not a toy codebase.
On the other side, there's SCONE — Anthropic's own December 2025 benchmark. Agents exploited 19 of 34 post-cutoff smart contracts, 55.8% success, $4.6M in simulated funds at an average API cost of $1.22 per contract. The comparable number 12 months earlier was about 2%.
Looks like agents are getting genuinely good at narrow, well-scoped vulnerability classes (Solidity, post-cutoff, bounded targets) and still bad at messy real-world codebases. But that's a guess and I'd rather hear pushback. Happy to get into methodology, the spots where Chainalysis, Immunefi, and Web3IsGoingJustGreat don't line up, or specific cases. 28 references at the end of the piece.

I'm sure you meant well and only used it for editing, etc. etc., and I agree AI is good.
In any case, I can't trust AI on AI, especially with such a stark headline from someone outside Anthropic. (how do you know it was a solo user with Claude?)
This is either breaking news that you for some reason delegated to an overly verbose post written by AI, or, its an almost-true-but-not-quite clickbait title, and I don't have the domain chops to know. Impossible spot to be in as a reader.

Anthropic has a vested interest in making their LLMs look advanced, powerful and dangerous. This is the company that is explicitly pro-regulation, who has donated $20M to a PAC for pro-regulation candidates, and whose own competitors accuse of being pro-regulatory capture. We should take their benchmarks and their "Mythos is too dangerous for you mere mortals" statements with a big ass grain of salt, because it plays directly into that regulation angle they're playing. Anthropic wants frontier model development locked up, with only a few select stewards of humanity holding the keys.
