Banks Could Collapse in an Instant: What is Mythos That's Making the World Panic?

Anthropic’s latest AI model, Mythos, is being described as a threat to traditional software security. Reports suggest that numerous companies, including the banking industry in the United States (US), could potentially fall victim to this model. Anthropic explains that during testing, Mythos was able to reveal thousands of vulnerabilities in every major operating system and web browser. The company has also highlighted issues upon introducing Mythos. According to Anthropic, this model could pose risks to the economy, public safety, and national security if misused. Experts have echoed similar sentiments, warning that Mythos can identify and exploit previously unknown vulnerabilities. This capability is even faster than companies’ ability to patch them, as cited from Reuters on Tuesday (21/4/2026). Moreover, its advanced coding and autonomous capabilities could accelerate cyber attacks. The impact would be felt in sectors like banking, which rely on complex, interconnected, and often outdated technology. These security concerns mean Mythos cannot be released widely. The company is only granting access to tech giants such as Amazon, Microsoft, Nvidia, and Apple. Access has since been expanded to more than 40 additional organisations, those working to build or maintain critical software infrastructure. A previous Reuters report also stated that US Treasury Secretary Scott Bessent and Fed Chair Jerome Powell met with the heads of major banks to discuss the potential risks from Mythos. Not just in the US, concerns about Mythos have reached the UK. Local authorities have spoken with major banks and cybersecurity officials about emerging potential risks. Security measures are also being taken in Germany. The President of the German Banking Association and CEO of Deutsche Bank, Christian Sewing, said banks have been in close contact with European regulators regarding Mythos.
