she said.<h2>Central banks globally on alert</h2>Regulators in other regions are taking similar steps.The Reserve Bank of Australia on Wednesday said it was closely monitoring developments and &#34;engaging with peer regulators, government and regulated entities.&#34;Meanwhile, the Reserve Bank of New Zealand on Wednesday described the risks as “developing” and confirmed it was coordinating with domestic and Australian counterparts.India has also joined the global effort.According to a Reuters report, the Reserve Bank of India is in discussions with international regulators, lenders, and government officials to evaluate potential threats.Preliminary assessments suggest the model could accelerate the discovery and exploitation of software vulnerabilities, raising cybersecurity concerns.The issue has reached the highest levels of global policymaking.Canadian finance minister François-Philippe Champagne told the BBC the model had been discussed at a recent International Monetary Fund meeting in Washington.&#34;Certainly it is serious enough to warrant the attention of all the finance ministers,&#34; he said, describing the technology as an &#34;unknown unknown&#34;.Similarly, Bank of England chief Andrew Bailey warned that authorities are closely evaluating the implications.“We are having to look very carefully now at what this latest AI development could mean for the risk of cyber crime,” he told the BBC.<h2>A double-edged sword for cybersecurity</h2>Although Mythos was designed for defensive cybersecurity applications, its capabilities have sparked alarm.Anthropic said early testing revealed “thousands” of significant vulnerabilities across major operating systems and web browsers.On Tuesday, Bundesbank President Joachim Nagel described the model as a “double-edged sword.”&#34;It could be used not only to improve digital security systems, but also to leverage their vulnerabilities for malicious purposes.&#34;Experts say the concern lies in the speed and scale at which such an AI system can identify and exploit weaknesses—far outpacing traditional security responses.<h2>Why has Anthropic restricted access to the model?</h2>Anthropic has restricted access to the model through a controlled initiative called Project Glasswing.Select organisations, including Amazon, Microsoft, Nvidia, and Apple, have been granted early access, alongside dozens of entities responsible for maintaining critical digital infrastructure.In a launch video, Dario Amodei said the company had offered to collaborate with US authorities to “help defend against the risk of these models.”Testing by independent researchers, including so-called “red teams,” has highlighted the model’s advanced capabilities.According to Anthropic, Mythos can autonomously identify critical bugs in legacy systems and even suggest methods to exploit them.&#34;Mythos Preview has already found thousands of high-severity vulnerabilities, including some in every major operating system and web browser,&#34; the company said.&#34;Given the rate of AI progress, it will not be long before such capabilities proliferate, potentially beyond actors who are committed to deploying them safely.&#34;<h2>Risks highest in legacy systems</h2>The potential threat is particularly acute in sectors that rely on complex and ageing infrastructure.A report by Bain &amp; Company noted that industries such as energy, manufacturing, and transportation could face heightened risks due to outdated systems that are difficult to patch.Banks, too, are vulnerable given their reliance on interconnected systems, some of which date back decades.However, the report emphasised that the risks are manageable with strong cybersecurity practices.&#34;The threat is serious, but it is not insurmountable, and strong cybersecurity foundations are your best defense,&#34; it said, adding that existing safeguards such as network segmentation, access controls, and anomaly detection can provide significant protection.<h2>Focus shifts to preparedness over panic</h2>Rather than rushing to develop entirely new AI-specific defences, experts argue that organisations should prioritise strengthening existing security frameworks.Recommendations include setting up dedicated AI threat response teams, improving baseline cybersecurity measures, and addressing vulnerabilities in operational technology environments.As access to powerful AI systems expands, regulators and companies alike face a balancing act—leveraging the benefits of innovation while guarding against unintended consequences.The rapid global response to Mythos suggests that policymakers are keenly aware of the stakes.Whether these early efforts will be enough to mitigate the risks posed by next-generation AI remains an open question.The post Why Anthropic’s Mythos AI has regulators, central banks on edge appeared first on Invezz</div>

Financial regulators globally are increasing scrutiny of Anthropic's AI model, Mythos, due to concerns over cybersecurity vulnerabilities it may expose in financial systems. Japan's Financial Services Agency is convening major banking groups to assess risks, while central banks in Australia, New Zealand, and India are also monitoring developments. The model, designed for cybersecurity, has raised alarms for its potential to exploit software vulnerabilities. Anthropic has restricted access to the model, allowing only select organizations to test it, as concerns grow over its implications for cybercrime and legacy systems.
