A hacker infiltrated OpenAI's internal messaging systems last year, stealing details about the design of its AI technologies, according to Reuters' sources familiar with the matter. The breach involved discussions on an online forum where employees exchanged information about the latest AI developments. Crucially, the hacker needed access to the systems where OpenAI builds and houses its AI.

OpenAI, backed by Microsoft, did not publicly disclose the breach, as no customer or partner information was compromised. Executives briefed employees and the board but did not involve federal law enforcement, believing the hacker had no ties to foreign governments.

In a separate incident, OpenAI reported disrupting five covert operations that aimed to misuse its AI models for deceptive activities online. The issue raised safety concerns and prompted discussions about safeguarding advanced AI technology. The Biden administration plans to implement measures to protect US AI advancements from foreign adversaries. At the same time, 16 AI companies have pledged to develop the technology responsibly amid rapid innovation and emerging risks.
