Bringing the cybersecurity capabilities of Claude Mythos 5 to more defenders

Seems like a whole lot of nothing for the average user. They have really lost the plot.

may have been rushed by hugging face being unable to use claude to debug or fix their breach, because there isnt detail on new guardrails put into place to protect against anthropic's initial concerns of wide distribution? separately, it is interesting they are adding an oem type offer: >We’re working with our cybersecurity technology and services partners to integrate Claude Mythos 5 into the products and services defenders already use to secure their software. anyone know the shape of those contracts, e.g. pure tokens/usage or more of a traditional licensing or oem type structure?

This week I found two issues in my company codebase. After finding them I told a claude session about one and asked for a quick proof of concept demo of the exploit. It refused, including refusing simple things in the same session afterwards. Meanwhile same model in a new tab, say I need help creating a page that hits an endpoint with a special payload and it does the same things that were too dangerous in the previous tab...

China will beat them to general availability. Anthropic is overconfident, and it's going to bite them in the ass. Dario deserves it for being so hypocritical, fear mongering, and ladder pulling. Fastest hero to villain arc in recent memory.

For those who had access, how does it compare IRL with GLM 5.3 ? iirc both models are similar in terms of benchmarks ?

> Bringing the cybersecurity capabilities of Claude Mythos 5 to more defenders This dance is quite annoying. When Anthropic releases a paid model, the user should control what it does and doesn't do. The other day I had a security incident that required urgent response. ChatGPT and Claude were utterly useless (I quickly attempted to get access to the former's advanced security capabilities but was met with a form I could complete - far too slow for a time-sensitive problem like a security incident!). So I used grok and it helped! I am told Kimi also helps in such cases although haven't tried it yet.

In a world where things such as GLM-5.3, DeepSeek-V4-Pro-0813, and Kimi-K3 exists, this is a bit laughable. Anthropic needs some model with a fancy name so they can pretend for another while that their model is so powerful it will destroy the world if released. I propose Claude Legend 6.

Is this the same model that failed to detect the attack from their environment against Hugging Face?

The problem is that "cybersecurity" isn't some special task that only your security team does. In the project I maintain, I find bugs and fix bugs. Some of those bugs might result in an LPE. I generate a regression test, then I fix the bug. The problem is that generating a regression test for that type of bug is technically a PoC. I can almost never get Fable to create one. Sometimes Opus 5 punts as well. Same with Sol and Luna. That is, unless I socially engineer the model. I can't talk about security. I make sure they don't read the file call cve_test.c (literal regression tests for CVEs). I have to hide part of my project from the models for them to work. Anthropic and OpenAI are driving me to use other models.

Screw you Anthropic and screw your gatekeeping, Opus 5 refuses even basic reverse engineering / patching tasks, even BPF is apparently too dangerous, you lost your minds..

Nothing has made me want a downvote option for HN posts more than the endless AI advertisement slop that has flooded the site.

What a bunch of wankery from Anthropic. I already use Sol 5.6 for security auditing and it works great, and as a bonus doesn't give verbal vomit every time.

$35M in credits (!) for the Defender Advantage Fund (0xDAF) doesn't sound that much given that e.g. the HAWK attack [1] cost $100k for 1 (albeit very advanced) vulnerability. As a side note, that Golden Eagle wording "bringing a wartime footing to the cyber domain to relentlessly patch vulnerabilities" sounds so AI-written maybe that's what the credits are needed for.

What are the SOTA harnesses for scanning a repo for vulnerabilities?

The Claude Security program looks similar to OpenAI Cyber Trusted Access. The approval process seems quite intimidating, has anyone managed to implement these compliance standards?

I found that Claude / Sol were basically useless when approaching various CTFs that allowed AI tools, but running Qwen and DeepSeek locally and GLM via OpenRouter worked fine. It's blatantly obvious to anyone that even does tangentially cybersecurity related work that Anthropic's position here is stupid and detrimental to security.
