Kyiv • UNN
An unknown individual, impersonating Secretary of State Marco Rubio, used an AI voice and Signal to contact five government officials, including three foreign ministers. The campaign began in mid-June 2025 using a fake account.
At least five government officials, including three foreign ministry representatives, a US governor, and a member of Congress, were forced to confront Rubio's voice and writing style. This is reported by The Washington Post, according to UNN.

An imposter posing as US Secretary of State Marco Rubio used an AI-generated voice to call high-ranking officials
The unknown person contacted at least five government officials. According to WP, among these individuals:
- three foreign ministers (it is not reported who exactly, which countries);
- a governor;
- a member of Congress.
Reference
The imposter used both text messages and the encrypted messaging app Signal. The latter, as is already known, is widely used by the Trump administration.
The impersonation campaign began in mid-June 2025. Someone created a Signal account using the username "[email protected]."
This address, under the guise of Marco.Rubio, was used to contact foreign and domestic diplomats and politicians. The latter allegedly suspected nothing
Important: the name [email protected] is not a real email address.
What were these messages from pseudo-Rubio?
According to WP, the imposter, posing as Secretary of State Marco Rubio, left voice messages on Signal to at least two selected individuals.
In one case, a text message was sent inviting to chat on Signal.
It should be noted: all officials refused to discuss the content of the messages or the names of the diplomats and officials referred to.
At the same time, the State Department responded that it would "conduct a thorough investigation and continue to take precautions to prevent this in the future."
Recall
US Secretary of Defense Pete Hegseth shared details of a March attack on Iran-linked Yemeni Houthis in a message group that included his wife, brother, and personal lawyer.
The exposure of the second Signal chat, as indicated, raises even more questions about Hegseth's use of a non-classified messaging system to report highly sensitive security details.
