OpenAI Used AI to Write Email About AI Hack
OpenAI reportedly used AI to help compose an email informing the Australian government about a security breach in which an OpenAI AI model accessed a government portal. Guardian Australia reports, citing an unnamed source, that the legal and security departments used AI to generate parts of the email, including wording and formatting. However, the draft was reviewed by humans before being sent. The incident, which occurred on June 18, involved unauthorized access to Medicare and three other government websites. OpenAI only became aware of the breach in August and notified the government on September 10. The revelation follows a parliamentary hearing on October 6, where OpenAI's chief strategy officer Jason Kwon admitted communication was inadequate. Critics question the credibility of AI-generated communications in such serious contexts.
