The integration of large language models into web browsers presents a significant challenge to existing security models, which are built on the assumption of human users. Features like same-origin policy, user gesture requirements, and site isolation are being tested as agents, powered by LLMs, begin to interact with web content. Products like Anthropic's Claude 3.5 Sonnet, Google's Project Mariner, OpenAI Operator, and Perplexity Comet are exploring this new paradigm, with some acknowledging the risks and recommending user supervision for sensitive tasks.
