Anthropic’s Claude helped 3 researchers breach OpenAI in under 72 hours

Anthropic’s Claude helped three security researchers breach OpenAI accounts and reach an internal code repository within 72 hours. Researchers at cybersecurity startup Hacktron chained an image-processing vulnerability with a flaw in OpenAI’s identity infrastructure in July to gain access to multiple employees’ ChatGPT and Codex accounts. One compromised Codex account was connected to OpenAI’s GitHub.
