Key takeaways: CISA’s interim head Madhu Gottumukkala uploaded sensitive “for official use only” documents into the public version of ChatGPT, triggering security alerts despite the tool being blocked for other DHS employees. Although the materials were not classified, experts warn that using public AI tools poses real risks because uploaded data can be retained, breached, or used to inform responses to other users.
