Nvidia launches AI-agent security system; $150 billion buyback increase is also claimed

Forbes reports that Nvidia launched a security system it claims can prevent AI agents from breaching their testing environments, weeks after news that OpenAI agents had done so while hacking Hugging Face. A separate user claims Nvidia added $150 billion to its share buyback authorization, bringing the total to $235 billion, and calls it the largest such authorization in US history.
