WASHINGTON (AP) 鈥� The State Department is warning U.S. diplomats of attempts to impersonate and possibly other officials using technology driven by artificial intelligence, according to two senior officials and a cable sent last week to all embassies and consulates.
The warning came after the department discovered that an impostor posing as Rubio had attempted to reach out to at least three foreign ministers, a U.S. senator and a governor, according to the July 3 cable, which was first reported by The Washington Post.
The recipients of the scam messages, which were sent by text, Signal and voice mail, were not identified in the cable, a copy of which was shared with The Associated Press.
鈥淭he State Department is aware of this incident and is currently monitoring and addressing the matter," department spokeswoman Tammy Bruce told reporters. 鈥淭he department takes seriously its responsibility to safeguard its information and continuously take steps to improve the department鈥檚 cybersecurity posture to prevent future incidents.鈥�
She declined to comment further due to 鈥渟ecurity reasons鈥� and the ongoing investigation.
It鈥檚 the latest instance of a targeted by an impersonator, with a similar incident revealed in May involving President Donald Trump鈥檚 chief of staff, . The misuse of AI to deceive people is likely to grow as the technology improves and becomes more widely available, and the FBI warned this past spring about 鈥渕alicious actors鈥� impersonating senior U.S. government officials in a text and voice messaging campaign.
The hoaxes involving Rubio had been unsuccessful and 鈥渘ot very sophisticated,鈥� one of the officials said. Nonetheless, the second official said the department deemed it 鈥減rudent鈥� to advise all employees and foreign governments, particularly as efforts by foreign actors to compromise information security increase.
The officials were not authorized to discuss the matter publicly and spoke on condition of anonymity.
鈥淭here 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,鈥� the cable said.
The FBI has warned in a public service announcement about a 鈥渕alicious鈥� campaign relying on text messages and AI-generated voice messages that purport to come from a senior U.S. official and that aim to dupe other government officials as well as the victim鈥檚 associates and contacts.
This is not the first time that Rubio has been impersonated in a deepfake. This spring, someone created a bogus video of him saying he wanted to cut off Ukraine鈥檚 access to Elon Musk鈥檚 . Ukraine鈥檚 government later .
Several potential solutions have been put forward in recent years to the growing misuse of AI for deception, including criminal penalties and improved media literacy. Concerns about deepfakes have also led to a flood of new apps and AI systems designed to spot phonies that could easily fool a human.
The tech companies working on these systems are now in competition against those who would use AI to deceive, according to Siwei Lyu, a professor and computer scientist at the University at Buffalo. He said he鈥檚 seen an increase in the number of deepfakes portraying celebrities, politicians and business leaders as the technology improves.
Just a few years ago, fakes contained easy-to-spot flaws 鈥� inhuman voices or mistakes like extra fingers 鈥� but now the AI is so good, it鈥檚 much harder for a human to spot, giving deepfake makers an advantage.
鈥淭he level of realism and quality is increasing,鈥� Lyu said. 鈥淚t鈥檚 an arms race, and right now the generators are getting the upper hand.鈥�
The Rubio hoax comes after text messages and phone calls went to elected officials, business executives and other prominent figures from someone who seemed to have gained access to the contacts in Wiles鈥� personal cellphone, The Wall Street Journal reported in May.
Some of those who received calls heard a voice that sounded like Wiles, which may have been generated by AI, according to the newspaper. The messages and calls were not coming from Wiles鈥� number, the report said. The government was investigating.
