Researchers have discovered a method to decrypt the internal reasoning processes of advanced AI models like GPT-5, Claude Opus, and Gemini. This attack, costing approximately $720, exploits a key management flaw that allows weaker models to act as oracles for decrypting encrypted "chain of thought" data. The vulnerability could expose proprietary reasoning methodologies, sensitive user data, and bypass safety systems. All three major AI providers, OpenAI, Anthropic, and Google, reportedly patched the core vulnerability before the research was publicly disclosed. AI
