Claude Mythos AI Has Governments Terrified

Anthropic just built an AI model so powerful that finance ministers stopped their IMF meetings to talk about it. So the Bank of England governor, the Barclays CEO, the Canadian finance minister, the US treasury, all of them in the same week publicly warned that Claude Mifas could be a serious threat to the global financial system. And here's what makes this wild. The model hasn't even been released to the public yet.

This is the Claude Mifas story. I'm gonna walk you through exactly what it is, what it actually does, what the top banks and governments are scared of, and what it means for every business owner watching this right now. Let's start with what actually happened. So earlier this month, Anthropic revealed a new model called Mifas.

Developers who tested it, the people whose whole job is to find out what AI models do when they go wrong, said Mifas was quote, strikingly capable at computer security tasks. What does that mean? It means this model is very, very good at finding weaknesses in software, operating systems, financial systems, web browsers, the kind of systems that banks, hospitals, governments, and businesses run on every single day. And not just finding those weaknesses, exploiting them.

Anthropic itself said the model had already exposed multiple security vulnerabilities in some critical operating systems, financial systems, and web browsers. So they didn't release it. Instead, they made it available to a small group of people. Amazon, web services, CrowdStrike, Microsoft, Nvidia.

Part of something called Anthropic Project Glasswing, described as an effort to secure the world's most critical software. The idea is you let the most capable AI find all the holes before the bad guys do, right? And then you fix them before Mifas ever goes public. That's the plan.

Whether it works is a whole other conversation, because here's what started happening next. The IMF held its annual meeting in Washington, D.C. this week. Finance ministers and central bank governors from around the world all in the same room.

And Mifas came up a lot. Canadian finance minister Francois-Philippe Champagne told the BBC, certainly it is serious enough, to warrant the attention of all finance ministers. He compared it to the Strait of Hormuz, the chokepoint that controls global oil supply. Except with the Strait of Hormuz, he said you know where it is and how large it is.

With Anthropic's model, he said it's the unknown unknown. Think about that for a second. One of Canada's most senior finance officials is comparing an AI model to a global infrastructure chokepoint and saying the scariest part is that nobody fully understands it yet. Now inside the AI Profit Boarding, we've got a full breakdown of where AI models like Mifas fit into the broader AI security picture.

And more importantly, a 30-day roadmap on how businesses like yours can use AI automation to get ahead right now before this space gets even more crowded. You get four weekly coaching calls where we go deep on what these developments mean for your business. 2,800 business owners already inside, many of them using AI to automate lead generation content and client work right now. If you want the playbook for building with AI in this environment, the link is in the comments and description or just go to the AIprofitboarding.com Now the Barclays CEO CS Venkata Krishnan was a bit more direct.

He told the BBC, it's serious enough that people have to worry. We have to understand it better. We have to understand the vulnerabilities that are being exposed and fix this quickly. And then Bank of England Governor Andrew Bailey said this, we are having to look very carefully now what this latest AI development could mean for the risk of cybercrime.

The consequence could be that there is a development of AI, of modeling, which makes it easier to detect existing vulnerabilities in sort of core IT systems. And then obviously cybercriminals, the bad actors could seek to exploit them. That's the Bank of England, not a Reddit forum, not a tech blogger, the Bank of England saying this. And the U.S.

Treasury confirmed it had already raised the issue with major banks, encouraging them to test their systems before any public release of MIPHOS. So now you've got the question everyone's actually asking, is MIPHOS as dangerous as everyone is making it sound? Here's where it gets complicated. The UK's AI Security Institute was given access to a preview version of MIPHOS.

They published the only independent report we have on it so far. And their finding is that MIPHOS is capable, it can find security holes in undefended environments. But their report also noticed and noted it wasn't dramatically better than Cord Opus 4, Anthropic's previous top model. They said our testing shows the MIPHOS preview can exploit systems with weak security posture.

And they wrote and it is more likely that more models with these capabilities will be developed. So yes, it's a real capability. But some cyber security experts are pushing back on the level of panic, pointing out that the wider industry hasn't been able to test it properly yet, and that we can't fully measure how capable it really is until more people get hands on time with it. This is also not the first time an AI company has held back a model and cited safety concerns.

In February 2019, OpenAI did the same thing with GPT-2. They said it was too dangerous to release. They staggered the rollout, and some critics said at the time it was more about generating hype than genuine risk. Whether that's true of MIPHOS, nobody can say for certain yet.

But the difference this time is the scale of institutional response. Finance ministers don't usually show up to discuss AI models. Central bank governors don't usually give BBC interviews about AI safety. Something has shifted here.

On Thursday, as all of this was playing out, Anthropic actually released a new version of an existing model called OPUS, the stated reason to allow MIPHOS' cyber capabilities to be tested in less powerful systems. Essentially giving the security community a smaller version of the capability so they can start building defenses before the full thing ships. Top bankers are also being given direct access to test their own systems. The idea is to find out what MIPHOS would do to their infrastructure so they can patch it before the public release.

And here's a part of this story that is actually more important than everything I've told you so far. A financial industry source told the BBC this week that another prominent US AI company could soon release a similarly powerful model, but without the same safeguards. Listen to that again. Another major AI company, similar capability, no equivalent safeguards.

Anthropic's approach with Project Glasswing, controlled access, coordination with banks and governments, staged testing, might be the responsible path. But it only matters if everyone follows him. Right now, there's no guarantee of that. James Wise is a partner of Borderton Capital and chairs something called the Sovereign AI Unit, a venture capital fund backed by 500 million pounds in UK government funding, investing specifically in British AI companies.

He actually told the BBC today's program that MIPHOS is the first of what will be many more powerful models that can expose security vulnerabilities. And then he said something that should stick with you. We hope the models that expose vulnerabilities are also the models that will fix them. That's the bet.

AI finds holes, AI patches holes. You need the same capability to do both. The danger is when the finding holes part races ahead of the fixing holes part, right? Which brings me to what this actually means for your business.

Because if you own a business, run an agency, sell products online, you rely on platforms, software, payment systems, email, cloud tools, all of those run on operating systems and infrastructure. The same infrastructure that MIPHOS has reportedly been poking holes in. You can't do much about what Anthropic builds or what the IMF discusses, but you can pay attention to what's coming. And what's coming is a world where AI powered security scanning gets dramatically better.

And so does AI powered attacking. Those two things move together. The businesses that get ahead of this are the ones who understand that AI space isn't just about productivity tools and content generation. Security is a big part of the picture now.

The same AI that helps you write emails can also, in a more powerful form, start finding gaps in the systems you use every day. And the reason finance ministers are sitting in rooms talking about this is because they know that when these models get out into the hands of everyone, not just CrowdStrike and AWS, the attack surface for every institution on earth changes, potentially overnight. This is why Anthropic's staged approach actually matters, not just for banks, but for everyone. Because a model that can find zero day vulnerabilities across critical software, if released into the wild with no coordination, doesn't just threaten banks.

It threatens every single business that relies on the internet. Now, I want to be straight with you on one thing. The UK's AI Security Institute said Miphos wasn't dramatically better than Claude Opus 4. Some experts are urging caution about the level of alarm.

It's possible and worth noting that some of this response is driven by institutional risk aversion and the political reality of being seen to act when something new comes along. But the structural point stands regardless of how powerful Miphos specifically turns out to be. AI models are getting better at finding system vulnerabilities. More of them will be built.

And the question of who controls access to them, under what conditions, and with what in oversight, that's one of the most important governance questions in tech right now. Anthropic chose to coordinate with governments and banks, right? Someone else might not in the future. And that's what Francois-Philippe Champagne meant when he said, the unknown unknown.

It's not just Miphos, right? It's what comes next, and the next one after that. If you're a business owner, for example, watching this, here's what I'd take away from this story. First, the AI companies you depend on are building things they themselves consider too powerful to release without coordination.

That's not a reason to panic. It's a reason to pay attention. Second, the security implications of AI are going to start showing up in your world. Not just in banking, but in the software you use, the platforms you sell on, the tools you rely on.

Third, staying educated about what's actually happening in AI, not hype, but the real developments, is a competitive advantage. Most business owners have no idea this conversation is even happening at the IMF. You do now. Now, inside the AI Profit Boardroom, there are 2,800 business owners tracking exactly this kind of development and figuring out how to position their business as AI capabilities grow.

We've got four weekly coaching calls on how tools like Claude are changing what's possible for agencies, freelancers, e-commerce stores, and service businesses. There are daily tutorials specifically on how to use AI to get more customers and automate the stuff that eats your time. Not generic tutorials, but step-by-step playbooks built around the models and tools they're actually shipping right now. Plus, a prompt library, a 30-day roadmap, and a member map so you can connect with people near you who are building with the same tools.

There's always someone online 24-7. The link's in the comments inscription or go to the AIprofitboardroom.com. The MIPHA story is not finished. The model hasn't been released, the testing is still happening, and a second, potentially less careful competitor is already reportedly building something similar.

Pay attention to what happens next.
