Ben Horowitz: “Anthropic is one of the most negligent companies that we've ever seen in terms of security.” “I'll tell you a funny story. So when we first got Opus 4.5, we were doing cybersecurity checks for the firm. So we had an agent basically set up a website for a pet store. And then we took another agent and said, ‘Tell us if we can exploit that web store.’ And it gave us all the exploits it could find. So Opus 4.5 wrote really buggy code. Great. And then we said, ‘Oh, the SQL injection, is that actually exploitable that you found?’ And it goes, ‘Let's pop it open.’ And the agent using Opus 4.5 breaks into the website and steals all the customer data immediately. We then call Anthropic, and what they tell us is, ‘You prompted it wrong.’ Like that was their answer.”
