There’s an impersonator of Secretary of State Marco Rubio on the unfastened, and so they’re utilizing synthetic intelligence to focus on high-level officers.
First detected in mid-June, the AI-powered rip-off entails voice and textual content messages that mimic Rubio. The messages are despatched through Sign from an account labeled “Marco.Rubio@state.gov”—a pretend electronic mail designed to look official. Based on a State Division cable obtained by The Washington Submit, a minimum of 5 non-State Division officers have been contacted to date, together with three overseas ministers, a U.S. governor, and a sitting member of Congress.
Authorities nonetheless don’t know who’s behind the marketing campaign, however the State Division believes that the objective is to trick highly effective targets into sharing delicate data and account entry.
“The actor demonstrated in depth data of the division’s naming conventions and inner documentation,” the cable famous.
In a number of instances, the imposter left voicemails and even invited targets to proceed the dialog on Sign, a transfer specialists say ought to elevate pink flags.

“That is exactly why you shouldn’t use Sign or different insecure channels for official authorities enterprise,” mentioned Hany Farid, a UC Berkeley digital forensics knowledgeable.
However that warning is perhaps too late. Sign has already brought about hassle for the Trump administration. In March, former nationwide safety adviser Michael Waltz by accident added a journalist to a Sign group chat about U.S. assault plans in Yemen. The fallout led to Waltz’s removing and a halt in utilizing Sign for nationwide safety conferences. (Rubio has since taken over Waltz’s submit.)
Secretary of Protection Pete Hegseth didn’t assist both, with a report revealing that he shared particulars of a navy strike in a separate Sign chat together with his spouse, brother, and private lawyer.
The Rubio impersonation isn’t even the primary main scandal this yr. In Could, somebody breached White Home chief of workers Susie Wiles’ cellphone, pretending to be her in calls and messages to senators and enterprise leaders. President Donald Trump downplayed the incident on the time, calling Wiles “an incredible girl” who “can deal with it.”
The FBI hasn’t but commented on the Rubio impersonation, which is a felony.
In the meantime, the State Division is urging diplomats to report suspicious messages to the Bureau of Diplomatic Safety, and different officers are being directed to the FBI’s Web Crime Grievance Heart.
“There isn’t any direct cyber menace to the division from this marketing campaign,” the cable learn, “however data shared with a 3rd get together may very well be uncovered if focused people are compromised,” in line with Reuters, which additionally obtained the memo.
The cable additionally referenced a Russian-linked hacker in April that focused suppose tanks, Japanese European activists, and former State Division workers.
“As soon as malicious actors receive cellphone numbers linked to an official’s Sign account, the impersonation half is simple,” Farid mentioned.
However till the federal government stops counting on insecure messaging apps for delicate points, don’t be shocked if “Marco Rubio” retains calling.
