Last summer, the acting director of the US cybersecurity service CISA entered sensitive government documents into a public version of ChatGPT. This led to several internal security alerts and an investigation into the damage within the Department of Homeland Security (DHS). The documents in question were CISA contract documents marked for official use only. In that context, the ChatGPT incident takes on added significance, as it fits into a broader picture of concerns about governance and risk management. According to Ars Technica, the internal investigation into the uploads began last summer.
