An anonymous reader quotes a report from Politico: The interim head of the country’s cyber defense agency uploaded sensitive contracting documents into a public version of ChatGPT last summer, triggering multiple automated security warnings that are meant to stop the theft or unintentional disclosure of government material from federal networks, according to four Department of Homeland Security officials with knowledge of the incident. The apparent misstep from Madhu Gottumukkala was especially noteworthy because the acting director of the Cybersecurity and Infrastructure Security Agency had requested special permission from CISA’s Office of the Chief Information Officer to use the popular AI tool soon after arriving at the agency this May, three of the officials said. The app was blocked for other DHS employees at the time.

None of the files Gottumukkala plugged into ChatGPT were classified, according to the four officials, each of whom was granted anonymity for fear of retribution. But the material included CISA contracting documents (PDF) marked “for official use only,” a government designation for information that is considered sensitive and not for public release. Cybersecurity sensors at CISA flagged the uploads this past August, said the four officials. One official specified there were multiple such warnings in the first week of August alone. Senior officials at DHS subsequently led an internal review to assess if there had been any harm to government security from the exposures, according to two of the four officials. It is not clear what the review concluded.
