AI Scam Targets U.S., Foreign Officials; No Breach

In mid-June 2025, an unidentified individual used AI to impersonate U.S. Secretary of State Marco Rubio by mimicking his voice and writing style, targeting at least three foreign ministers, a U.S. governor, and a member of Congress through Signal and text messages. The scammer created a fake Signal account using a display name resembling Rubio’s official email to seek access to sensitive information or accounts. Officials assessed the attempts as unsophisticated and ultimately unsuccessful, with no breaches or responses reported. The State Department issued global warnings to both diplomatic staff and foreign partners, urging vigilance and prompt reporting of impersonation attempts. Investigations are ongoing to identify the perpetrator and prevent future incidents. The event is part of a broader trend of AI-driven impersonation scams targeting senior government officials and highlights growing cybersecurity concerns.
