The Rise of AI-Powered Impersonation Requires Urgent Multidimensional Action

AI Generated Image

A recent report revealed that an individual impersonating U.S. Secretary of State Marco Rubio used artificial intelligence to contact foreign ministers, senior U.S. officials, and lawmakers through the encrypted platform Signal. The impersonator replicated both voice and writing style using AI-powered tools, aiming to gain access to sensitive information or accounts.

This incident highlights a dangerous and escalating trend—the use of AI in high-level social engineering attacks targeting the core of diplomatic and national decision-making.

This message is especially important for senior government officials, VVIPs, and high-ranking stakeholders, who are increasingly targeted by sophisticated AI-driven impersonation campaigns. Awareness of these trends is no longer optional—it is a matter of national and organizational resilience.

A coordinated and multidimensional response is essential. Technical controls, digital identity verification, organizational training, and legislative reform must work together to counter this evolving threat landscape.
