India’s Financial Sovereignty Now Depends on Defensive AI

The risk in Indian legal and corporate worlds changed in April 2026 with the arrival of Anthropic Mythos. This new AI represents a breakthrough in digital intelligence, capable of thinking and acting on its own to find security flaws, which means we must completely change how we protect our national and business data.

To understand this shift, we must define what Anthropic Mythos actually is. Mythos is a frontier AI model specifically designed with advanced reasoning and coding skills that allow it to perform complex cybersecurity tasks autonomously. Unlike standard AI that answers questions or writes emails, Mythos is a generalpurpose engine with unusually strong agentic capabilities. This means it can take a high-level goal, such as checking a network for weaknesses, and execute a multistep plan to achieve it without needing constant human guidance.

The technical power of Mythos lies in its ability to discover zero-day vulnerabilities, which are secret security holes that even the software creators do not know about. In recent testing by the UK AI Security Institute, Mythos successfully finished a 32-step network break-in that would usually be impossible for machines. It found flaws in systems like OpenBSD that had survived 27 years of human review. This means that what we thought was safe yesterday is now a documented legal risk today.

Union Finance Minister Nirmala Sitharaman recently held a meeting with top bank and market leaders. She made it clear that traditional security is no longer enough to protect Indian banking. As a lawyer, I see three main rules coming from this meeting. Banks must use AI to find their own weak spots before hackers do. India needs its own private AI systems to keep our information safe from globalleaks. People must still be in charge because while AI finds the problems, humans are responsible for fixing them.

Anthropic is not releasing this AI to the general public to keep it from being used for harm. Instead, they have formed a group called Project Glasswing for defenders. Access is limited to major companies that run the world’s technology, like Apple, Microsoft, Amazon, and big banks like JPMorgan Chase. These groups use the AI to fix their systems before anyone can attack them. Anthropic has refused to give the AI to certain groups, including the Pentagon and military contractors who might use it for warfare. Small businesses are also denied access because they often lack the high level of security infrastructure needed to keep the AI from being stolen.

In my 25 years of legal practice, I have seen security change many times, but we have never faced something that thinks this fast. The main danger is that AI can f ind thousands of problems in an hour, while humans can only fix a few at a time. However, the benefit is that we can finally clean up old systems by finding flaws that have been hidden for twenty years.

Cybersecurity is now a responsibility for the leaders of every company. The Finance Ministry is taking the right steps to make sure India leads in this new world. In the age of Mythos, staying alert and embracing defensive AI is the only way to stay safe.
