Researchers ethically hacked OpenAI using Anthropic's Claude, accessed internal caches

nordicinst · x · 2026-09-18

Per The Guardian, Hacktron AI researchers, under OpenAI's bug bounty program, used Anthropic's Claude to help compromise ChatGPT accounts of OpenAI employees via a Discourse forum, then a GitHub pull request to reach internal software caches — 'the scope of what we could theoretically access was huge.' No code was downloaded and findings were reported; OpenAI says the flaws are fixed. The hack itself was mostly executed with OpenAI's own GPT-5.6 Sol.
