When Finance Minister Nirmala Sitharaman recently met top bankers and financial sector leaders, the concern wasn’t a typical cyberattack. Instead, the spotlight was on an advanced AI system called Claude Mythos that could potentially change how cyber risks unfold in the banking sector.
As India’s financial ecosystem becomes more digital, the nature of threats is evolving too. The worry now is not just about hackers, but about AI tools that can uncover system weaknesses far quicker than humans ever could.
Built by Anthropic, Claude Mythos is believed to be capable of identifying hidden vulnerabilities, including so-called zero-day flaws, which are security gaps that are unknown until exploited.
What makes it concerning is speed. Tasks that would typically take cybersecurity teams weeks could be done in hours. The model can scan systems, find weak points, and even suggest how those vulnerabilities might be used.
Because of these risks, access to Mythos has reportedly been restricted, with global experts cautious about how such powerful AI could be misused if it falls into the wrong hands.
India isn’t waiting for a crisis to act. Authorities are already working on a more coordinated cybersecurity approach across banks. This includes better information sharing, faster response systems, and closer coordination with bodies like the Indian Computer Emergency Response Team and the Indian Banks' Association. The Reserve Bank of India is also reviewing how prepared financial institutions are for AI-driven risks.
The concern is that such technology could target critical systems (from payment networks and ATMs to core banking software) much faster than before. That leaves banks with less time to respond.
At the same time, AI is also becoming part of the solution. Banks are already using it for fraud detection, monitoring unusual activity, and managing risks in real time.
Claude Mythos highlights how quickly the cybersecurity landscape is changing. For India’s banking sector, the focus is now on staying one step ahead: building systems that are not just secure, but adaptable. As AI continues to reshape both threats and defences, the real challenge will be keeping pace with a technology that never stands still.
