The headline is not misleading, the article actually links to the incident with OpenAI and Irregular which is here: https://openai.com/index/third-party-cyber-evaluations-invol...
But more to the point, the article is trying to paint this as some sort of coordinated plan just because there was a sandbox misconfiguration by Irregular. The fact that the most well known hacking scandal was due to a completely unrelated escape (zero day in Artifactory) makes the entire thesis of the article invalid.
