Someone has taken their face and used it to deceive thousands
Em São Paulo, o conselho regional de medicina documentou um esquema que explora a confiança depositada na figura do médico: atores contratados para simular especialistas em vídeos de produtos sem registro na Anvisa, e imagens reais de pessoas manipuladas por inteligência artificial sem qualquer consentimento. É uma fraude que se alimenta de duas fragilidades humanas ao mesmo tempo — a tendência de acreditar no que parece legítimo, e a dificuldade de provar o que não aconteceu. O caso coloca em evidência uma tensão crescente entre a velocidade da tecnologia e a lentidão das instituições que deveriam proteger o público.
- Atores são contratados deliberadamente para vestir jaleco e emprestar falsa autoridade médica a produtos que jamais passaram por aprovação regulatória.
- Outros nem sabem que participam: suas imagens são roubadas e reconfiguradas por deepfakes e sincronização labial por IA, fazendo-os 'falar' o que nunca disseram.
- Um ator descobriu sua face circulando em grupos de WhatsApp por todo o Brasil — e passou a receber acusações e insultos de desconhecidos que acreditavam ser ele o golpista.
- Enquanto ele gravava vídeos tentando se explicar, o estrago já se espalhava: reputação profissional, caráter e trabalho legítimo contaminados por uma fraude da qual não fazia parte.
- O conselho médico emitiu alertas, mas a fiscalização enfrenta um adversário que opera em múltiplas plataformas, jurisdições e tecnologias que evoluem mais rápido do que as ferramentas regulatórias.
O conselho de medicina de São Paulo documentou um esquema que funciona à luz do dia: atores contratados para se passar por médicos em vídeos que promovem produtos sem registro na Anvisa. Os vídeos são bem produzidos, convincentes, e aparecem em sites e redes sociais. A maioria das pessoas que os assiste não tem motivo para desconfiar do homem ou da mulher de jaleco branco.
Mas há uma camada ainda mais perturbadora. Alguns dos rostos nesses vídeos pertencem a pessoas que jamais concordaram em participar. Suas imagens foram roubadas e manipuladas por inteligência artificial — a tecnologia altera movimentos labiais, substitui diálogos inteiros, monta cenas que nunca existiram. O ator se vê na tela dizendo palavras que nunca pronunciou, recomendando produtos que nunca conheceu.
Um desses atores descreveu o momento em que descobriu o que havia acontecido. Vídeos com seu rosto começaram a circular em grupos de WhatsApp pelo Brasil. Quem os via acreditava que ele era um especialista médico endossando aqueles produtos. Sua conta nas redes sociais logo se encheu de mensagens raivosas — acusações, insultos, difamação. Ele passou a gravar seus próprios vídeos tentando explicar a situação, mas o dano já estava em curso. Sua reputação profissional, seu caráter, seu trabalho real como ator — tudo havia sido contaminado por associação com um golpe do qual não tinha qualquer parte.
Os produtos promovidos nesses vídeos nunca passaram pela Anvisa. Existem num vazio legal, protegidos pela negação plausível que a tecnologia deepfake oferece. Para os atores apanhados nessa armadilha, a violação é ao mesmo tempo pública e íntima: alguém tomou seu rosto, sua voz, sua imagem, e os usou para enganar milhares de pessoas.
O conselho médico nomeou o problema. Mas nomear não é resolver. Os fraudadores operam entre plataformas, fronteiras e tecnologias. As ferramentas tradicionais de regulação — licenciamento, fiscalização, processos de aprovação — se movem devagar. A tecnologia, não.
São Paulo's medical regulatory board has documented a scheme that operates in plain sight across the internet: actors hired to pose as doctors in videos promoting products that have never been approved by Brazil's health authority. The videos are polished, credible-looking, designed to persuade. They appear on websites and social media channels. They work because most people watching them have no reason to suspect the person in the white coat is not who they claim to be.
But there is a second, darker layer to this operation. Some of the actors whose faces appear in these fraudulent medical endorsements never agreed to participate at all. Their images have been stolen, manipulated using artificial intelligence, and repurposed to sell unregistered products. The technology allows fraudsters to alter lip movements, change dialogue entirely, or splice together fragments of legitimate video to create something that never happened. The actor sees themselves on screen, speaking words they never spoke, endorsing products they never knew existed.
One actor described the experience of discovering this had happened to him. Videos using his image began circulating on WhatsApp groups across Brazil. People who saw them believed he was a medical expert promoting these products. When his actual social media accounts filled with angry messages—accusations, insults, defamation—he had no immediate way to prove the videos were fake. He began posting his own videos trying to explain what had occurred, trying to separate himself from the fraud. But by then the damage was already spreading. His professional reputation, his character, his actual work as an actor—all of it had been contaminated by association with a scam he had nothing to do with.
The medical board's investigation reveals the scope of the problem. Actors are being hired deliberately to lend false authority to products without regulatory approval. Some know what they are doing. Others discover later that their images have been stolen and weaponized. The products themselves—whatever they claim to treat or cure—have never passed through Anvisa, Brazil's pharmaceutical regulatory agency. They exist in a legal void, marketed with the credibility of a doctor's endorsement, protected by the plausible deniability of deepfake technology.
For the actors caught in this trap, the consequences are immediate and personal. They face harassment from strangers who believe they are fraudsters. Their professional standing is questioned. The violation feels intimate because it is: someone has taken their face, their voice, their likeness, and used it to deceive thousands of people. The technology that makes this possible—AI-driven lip synchronization, voice synthesis, video manipulation—is becoming more sophisticated and more accessible. What was once the domain of specialized effects studios can now be done by anyone with the right software.
The medical board's warning signals that regulatory authorities are aware of the problem, but awareness and enforcement are not the same thing. The fraudsters operate across platforms, jurisdictions, and technologies. An actor in São Paulo can be impersonated by someone anywhere. A product manufactured nowhere can be promoted everywhere. The traditional tools of regulation—licensing, inspection, approval processes—move slowly. The technology moves fast.
What emerges from this is a collision between two vulnerabilities: the regulatory system's inability to keep pace with new methods of deception, and the actor's exposure to having their identity stolen and weaponized without consent or recourse. The medical board has named the problem. What happens next depends on whether authorities can move quickly enough to stop it.

So these are real actors, hired deliberately, to pretend to be doctors?
Some of them, yes. They're paid to appear in videos endorsing products that have no regulatory approval. It's straightforward fraud dressed up as medical expertise.
And the others—the ones whose images are being stolen?
They never agreed to anything. Someone took their face, used AI to manipulate their mouth and voice, and put words in their mouth. They discover it when strangers start attacking them online.
How does that even work technically?
Deepfake technology. Lip-sync software that can make someone appear to say things they never said. You can take a real video of an actor and completely change what comes out of their mouth.
And the products being sold—are they dangerous?
That's the point. They're unregistered. Nobody knows. They've never been tested or approved by health authorities. They could be harmless placebos or they could cause real harm. The regulatory system has no record of them.
Why target actors specifically?
Because they're recognizable. A face people trust, or at least recognize. It makes the product seem legitimate. And actors are visible enough that their images are easy to find and steal, but often not famous enough to have massive legal resources to fight back.
What's the real damage here—the fraud itself, or the violation of the actors?
Both, but they're connected. The fraud works because people believe the actor is a real doctor. The actor suffers because their reputation gets tangled up in a scam they had nothing to do with. The system that's supposed to protect public health fails, and individual people pay the price.
