New Delhi: India’s securities regulator has informed every broker, fund house, exchange, depository, and market intermediary in the country to immediately lock down their systems against a new generation of Artificial Intelligence (AI) tools capable of detecting and exploiting software vulnerabilities at machine speed, specifically naming Anthropic’s AI platform ‘Mythos’.

The Securities and Exchange Board of India (SEBI) issued the directive on 5 May in a circular signed by Deputy General Manager Mamata Roy and addressed to the entire regulated universe of Indian securities markets — from stock exchanges and mutual funds to credit rating agencies, custodians, portfolio managers, merchant bankers, and alternative investment funds.Claude Mythos Preview is a frontier artificial intelligence model built by Anthropic that found over 2,000 previously unknown software vulnerabilities in just seven weeks of testing — including flaws that had survived decades of human security review — and developing working exploits on the first attempt in over 83 per cent of cases. Anthropic judged the model too dangerous for public release and instead formed Project Glasswing, a controlled coalition of technology companies including Amazon Web Services, Apple, Microsoft, Google, and CrowdStrike, to deploy it exclusively for defensive purposes.
