US cybersecurity chief leaked sensitive government files to ChatGPT:
Report

The acting head of the US government's top cybersecurity agency
reportedly uploaded sensitive government files into a public version
of ChatGPT, triggering internal security alerts and a federal review.

A Politico investigation claims Madhu Gottumukkala, the interim
director of the Cybersecurity and Infrastructure Security Agency,
uploaded contracting documents marked "For Official Use Only" into
ChatGPT last summer.

The report says Gottumukkala requested a special exemption to access
ChatGPT, which is blocked for other Department of Homeland Security
staff.

Cybersecurity monitoring systems then reportedly flagged the uploads
in early August. That triggered a DHS-led damage assessment to
determine whether the information had been exposed.

Public versions of ChatGPT share user inputs with OpenAI, which
raised concerns inside the federal government about sensitive data
leaving internal networks.

CISA responds to ChatGPT investigation

CISA spokesperson Marci McCarthy told Politico that Gottumukkala "was
granted permission to use ChatGPT with DHS controls in place," adding
that the use was "short-term and limited."

Gottumukkala has served as acting director since May, while the
Senate has yet to confirm Sean Plankey as permanent head of the
agency.

The ChatGPT incident follows other reported issues during
Gottumukkala's tenure. Politico said he previously failed a
counterintelligence polygraph required for access to highly sensitive
intelligence. During congressional testimony last week, he rejected
that characterization when questioned.

The report lands as the administration of US President Donald Trump
continues to push AI adoption across federal agencies.

Trump signed an executive order in December aimed at limiting
state-level AI regulation, while the Pentagon has announced an
"AI-first" strategy to expand the military's use of artificial
intelligence.
