Setting this apart from typical web adverts featuring celebrity faces promoting dubious products, the company behind the ad, Incognito, was also misled into believing Bonnin had endorsed their product.

Expressing her dismay, Bonnin, renowned for her roles in “Bang Goes the Theory” and “Our Changing Planet,” described the experience as violating, albeit relieved that the product in question was merely an insect repellent.

The scammers employed a fabricated voice message, purportedly from Bonnin, granting consent for the advertisement. Initially resembling Bonnin's voice, the message gradually deviated in accent, arousing suspicions regarding its authenticity.

Howard Carter, CEO of Incognito, initially believed he was communicating directly with Bonnin, based on convincing voice messages endorsing the product.

The impersonator supplied Carter with a phone number and email address, along with contact details allegedly from the Wildlife Trust, where Bonnin serves as president.

Negotiations, conducted via WhatsApp and email, led experts to suspect the involvement of AI in creating a digital voice replica of Bonnin.

On March 13, Carter received what he believed to be a signed contract from Bonnin via email, prompting the transfer of £20,000 to an account linked to a digital bank on March 15.

Despite receiving campaign materials, subsequent emails from Incognito to the scammers went unanswered.

The fraudulent campaign launched using quotes and images provided by the scammers, only unraveling after Bonnin publicly disclaimed any involvement.

Expressing regret, Bonnin empathized with Incognito's predicament, emphasizing the need for vigilance when encountering seemingly too good to be true opportunities.


The Emergence of Deepfake Cloning

Instances like these are not isolated; AI-driven abuses have impacted various public figures, amplifying concerns surrounding digital impersonation.

In one incident, a fabricated audio of London Mayor Sadiq Khan surfaced, featuring contentious remarks just before Armistice Day. Similarly, a deepfake audio clip purportedly depicting Philippine President Ferdinand Marcos Jr. issuing directives against China has sparked alarm within Manila's government circles.

Moreover, audio deepfakes are actively employed in scams targeting individuals' accounts. For instance, a Vice journalist gained unauthorized access to his own bank account using an AI-generated replica of his voice.

These cases illustrate the capabilities of AI tools like Microsoft’s VASA-1 and OpenAI’s Voice Engine, which can craft convincing synthetic content. Although not yet publicly available, the underlying research reveals VASA-1's ability to generate remarkably authentic deepfake videos and voices using only a single photo and a brief audio snippet. Similarly, Voice Engine can replicate a voice with merely a 15-second sound recording.
