Anthropic's mysterious Mythos AI threatens to upend the infosec world

(2026/04/13)


Kettle Anthropic dropped a doozy on us this week with the launch of Mythos, an AI model it says is able to find and exploit zero-day vulnerabilities with a shocking level of ability.

This, of course, makes it a perfect topic for this week's episode of the Kettle, where host Brandon Vigliarolo is joined by APAC editor Simon Sharwood and senior reporter Tom Claburn to discuss all things Mythos.

The discussion this week covers just what the heck Anthropic has its hands on that's apparently too dangerous to release to the world (where have we heard [1]that before?), what this means for the cybersecurity community, and whether we should take Anthropic at its word or not.

Is Mythos just hype?

rgjnk

Of course it is. As noted it's not even an original play - we've heard it all before.

Ban it all, and send the rest to Section 4 of the Twenty-Fifth

Yeah, TechCrunch lists 10 countries that are on their way to ban [1]social media for kids ATM (Australia, Denmark, France, ..., UK) BUT the [2]Liberal Party of Canada (PM Mark Carney's) is looking to go a step further and ban BOTH social media and AI chatbots for kids (artificial conversation) ... a bit like [3]brominated vegetable oil (BVO) -- best banned for everyone's health!

About Mythos though, what's really funny imho, is if Anthropic is a certified, Orange-labeled, [4]Supply Chain Risk (SCR) , then by golly, are we in trouble now or what!!! ;) ;) ;)

Mythos?

So they are actually admitting so-called "AI" is a new religion, and nothing more?

Do you think the idiot investors will pay attention? Will they hell ... they have faith, they believe. No proof required.

Be afraid, very afraid.

Two heads are more numerous than one.
