US officials have revealed a potential security breach after a false actor managed to successfully impersonate Secretary of State Marco Rubio using AI-generated voicemails, fooling several foreign ministers.
We've seen plenty of stories involving artificial intelligence-based impersonations, including one woman who was swindled out of hundreds of thousands of dollars by a hospital-bound AI Brad Pitt.
However, the most recent high-profile case of AI-generated mimicry involved one of the most powerful individuals in global politics, and it was seemingly convincing enough to fool three foreign officials and two US government members.
How did the scammer impersonate Marco Rubio?
As reported by the BBC, the 'unknown actor' registered an account on messaging app Signal under the display name '[email protected]', and used AI tools to replicate the Secretary of State's speech in several voicemails.

As outlined in a State Department cable obtained by CBS News, the individual posing as Rubio contacted at least five different individuals, including a US governor and a member of Congress.
"The actor left voicemails on Signal for at least two targeted individuals, and in one instance, sent a text message inviting the individual to communicate on Signal," the cable outlined.
It remains unclear who was behind the attack, although it is believed that their motivations were to manipulate government officials both inside the United States and foreign nations in order to gain access to information, presumably of the powerful and confidential kind.
Is the government concerned about the breach?
As of right now, internal government communications appear to indicate that the attack has garnered significant concern, although it does raise questions about the ability of cybercriminals to infiltrate otherwise secure systems.
"There is no direct cyber threat to the department from this campaign, but information shared with a third party could be exposed if targeted individuals are compromised," the cable details.
It also added that the State Department "continuously takes steps to improve the department's cybersecurity posture to prevent future incidents," although it's unclear what form these improvements will take.
One thing that has been made clear after the fact is that the attack itself allegedly wasn't that impressive or convincing. According to the Associated Press, an anonymous US official has revealed that all five of the attempted hoaxes using Marco Rubio's voice were not only unsuccessful, but "not very sophisticated."
The ability for artificial intelligence to mimic the voices and even faces of famous individuals has been outlined in key government bills signed off by President Donald Trump, but this particular attempt at deception might not have been quite as convincing as the attacker would have hoped.
