Artificial intelligence was used to impersonate the voice of US Secretary of State Marco Rubio and place calls to foreign ministers and American officials, the State Department confirmed on Tuesday, raising further concerns over the growing use of deepfakes.
An unknown actor pretending to be Mr Rubio created an account on messaging app Signal in mid-June, using the display name “marco.rubio@state.gov” to contact at least three foreign ministers, a US senator and a governor, according to a memorandum first reported by The Washington Post. The imposter used AI to mimic Mr Rubio's voice and writing style.
Spokeswoman Tammy Bruce said the State Department was monitoring and addressing the situation.
"The department takes seriously its responsibility to safeguard its information and continuously take steps to improve the department's cyber-security posture to prevent future incidents for security reasons," Ms Bruce said.
The attempt to impersonate Mr Rubio highlights the rise of "deepfake" content, in which AI is used to manipulate media including video footage, images and audio recordings.
During the New Hampshire Democratic presidential primary last year, residents reported receiving deepfake robocalls from Joe Biden, who was running for re-election at the time. And in Slovakia's election last year, a viral deepfake audio recording purported to feature a candidate detailing how he had rigged the polls.
When AI makes it easier to infiltrate governments, it can lead to vulnerabilities affecting national security – and it is getting harder to distinguish truth from fiction.
A 2023 study by the University College London indicated that humans were unable to accurately detect more than a quarter of deepfake audio speech samples.
The study was conducted in the early days of AI audio and tools that have since improved dramatically. Some of the more recent AI apps only require a few snippets of audio to closely duplicate voices to say just about anything, even going so far as to mimic the idiosyncrasies of the person speaking.
As AI becomes more prevalent, however, efforts are under way to create technology that flags deepfake content.
In 2022, the UAE's Mohamed bin Zayed University of Artificial Intelligence was listed as an applicant on a US patent for a "video transformer for deepfake detection", which would consist of “a display device playing back the potential deepfake video and indicating whether the video is real or fake".
Hao Li, associate professor of computer vision at the MBZUAI, told The National last year that tremendous progress was being made with the deepfake detection technology.
“It’s becoming more and more difficult to create an undetectable deepfake,” he said.
But efforts to impersonate government officials might become more widespread in the months and years ahead as a result.
Leah Siskind, an AI research fellow with the Foundation for Defence of Democracies, said that deception fuelled by AI is a new frontier for influence operations.
"This is an urgent national security issue with serious diplomatic ramifications," she said.
"We've seen other instances of deepfakes of senior government officials used to gain access to personal accounts, but leveraging AI to influence diplomatic relationships and decision-making is a dangerous escalation."

Coffee: black death or elixir of life?
It is among the greatest health debates of our time; splashed across newspapers with contradicting headlines - is coffee good for you or not?
Depending on what you read, it is either a cancer-causing, sleep-depriving, stomach ulcer-inducing black death or the secret to long life, cutting the chance of stroke, diabetes and cancer.
The latest research - a study of 8,412 people across the UK who each underwent an MRI heart scan - is intended to put to bed (caffeine allowing) conflicting reports of the pros and cons of consumption.
The study, funded by the British Heart Foundation, contradicted previous findings that it stiffens arteries, putting pressure on the heart and increasing the likelihood of a heart attack or stroke, leading to warnings to cut down.
Numerous studies have recognised the benefits of coffee in cutting oral and esophageal cancer, the risk of a stroke and cirrhosis of the liver.
The benefits are often linked to biologically active compounds including caffeine, flavonoids, lignans, and other polyphenols, which benefit the body. These and othetr coffee compounds regulate genes involved in DNA repair, have anti-inflammatory properties and are associated with lower risk of insulin resistance, which is linked to type-2 diabetes.
But as doctors warn, too much of anything is inadvisable. The British Heart Foundation found the heaviest coffee drinkers in the study were most likely to be men who smoked and drank alcohol regularly.
Excessive amounts of coffee also unsettle the stomach causing or contributing to stomach ulcers. It also stains the teeth over time, hampers absorption of minerals and vitamins like zinc and iron.
It also raises blood pressure, which is largely problematic for people with existing conditions.
So the heaviest drinkers of the black stuff - some in the study had up to 25 cups per day - may want to rein it in.
