Imposter Videos Mimic Real Doctors, Spread Fake Medical Tips

Dr. Joel Bervell, widely recognized for his debunking of health misinformation on social platforms, was alerted by followers this year about a suspicious video featuring his likeness. Though the face matched his, the voice did not.

"It was unsettling," Bervell expressed. "While it appeared to be me, it was endorsing a product I had never associated with, using an unfamiliar voice."

The video, a product of deepfake technology, is indicative of a rising trend in which artificially generated content showcases fictitious medical experts, cybersecurity specialists have noted. This fraudulent material is reaching an ever-widening audience across TikTok, Instagram, Facebook, and YouTube, Bervell recounted.

Rise of Fictitious Health Experts on Social Media

In a CBS News inquiry, numerous accounts and over a hundred videos surfaced across social sites where either phony physicians or appropriated identities of real doctors dispensed advice or pitched products, primarily tied to beauty, wellness, and weight management. Frequently discovered on TikTok and Instagram, these videos attracted millions of views.

A significant number of these videos centered around product sales, often through independent websites or known e-commerce platforms, with audacious claims like being "96% more effective than Ozempic."

Detecting and Responding to Deepfake Threats

ESET, a cybersecurity firm, recently assessed such content and identified over 20 TikTok and Instagram profiles using AI-generated personas to market products, according to researcher Martina López. "The reach of this content widens as videos go viral or accounts gain followers," López commented.

Queries from CBS News to TikTok and Meta, Instagram's parent company, revealed both platforms had removed videos highlighted by the news outlet for breaching their guidelines. YouTube maintained that the highlighted videos complied with its rules but clarified its policy allows users to request removal of such simulations consented upon.

The platforms are working to remove or limit such content, with TikTok reporting the proactive removal of a vast majority of policy-violating AI-generated media between January and March.

Challenges in Identifying Deepfake Content

Scammers exploit sophisticated AI tools to enhance content quality, complicating detection on small screens, said Tony Anscombe, ESET's chief security evangelist. Some signs of deepfakes include visual glitches or robotic tones lacking emotional authenticity.

It's crucial to maintain skepticism towards extravagant claims, urging individuals to independently verify such information. "Question everything and assume nothing," Anscombe advised. "When faced with bold promises, seek independent sources, avoid clicking provided links, and verify through trusted means."

Concerning Impact on Public Trust in Medicine

Videos featuring Bervell's likeness were eventually removed after his followers reported them. He expressed concern over the detrimental effect such deepfakes could have on public faith in medical experts and the healthcare industry at large. "When fantasy masquerades as expertise, it blurs the line between fact and fiction, complicating the public's ability to trust scientific declarations or medical advice," he concluded.
