A first-instance criminal court in São Paulo state convicted a man who worked at a health facility of distributing a nude image without consent (article 218-C of the Penal Code), according to a report by Diário de Justiça of the sentence released on 31 July 2026. The sentence records that a woman who worked at the same facility learned on 30 May 2025, in a call from the head nurse, that an intimate image attributed to her was circulating among staff, and recognised it as an AI montage made from clothed photos she had posted on Instagram; the defendant followed her account. In his testimony he admitted using artificial intelligence to produce a nude image of her, saying he meant to defend her against a remark about her, and denied sharing it with anyone but the head nurse, who confirmed receiving it from him. The judge held that article 218-C also covers artificially produced nudity and found that two people received the material. The court took into account her reported anxiety crises, psychological treatment and a workplace that had become hostile. The sentence of one year, one month and ten days was set in the open regime and replaced by community service and a payment of one minimum wage; no minimum compensation was fixed because she had filed a separate civil claim. Any appeal is not reported.

A woman in Porto Alegre, Brazil, saw an online video in which the model Gisele Bündchen appeared to promote a free skincare kit, paid the R$44.57 shipping fee and received nothing. Her police report, registered on 4 August 2024, led the Rio Grande do Sul Civil Police to Operation Modo Selva. On 1 October 2025 police executed 26 court orders in five states against a group they say used deepfake videos of celebrities, including Gisele Bündchen and several TV presenters, in fake product promotions; four people had been arrested by the time of the reports. The investigating delegate said the criminals had created a deepfake of the model's image and voice. Police say the scheme moved at least R$20 million, and assets worth up to R$210 million were frozen. The model thanked police for finding criminals who use artificial intelligence for online scams. No charge or trial outcome has been reported since.

A professional voice actor sued a São Paulo shopping centre, saying it used the actor's voice without authorisation in a marketing campaign shown on YouTube, and claimed lost earnings and moral damages. The centre answered that the voice was not the actor's but a synthetic voice produced with Microsoft's text-to-speech service, available to the public. According to the legal news site ConJur, a judge of the 18th Civil Court accepted that the voice was produced synthetically and dismissed the claim; on appeal the actor argued that a notarised record attesting to the similarity of the voices had never been assessed. The 6th Private Law Chamber of the São Paulo Court of Justice annulled that judgment for curtailment of the defence, holding that the use of AI does not by itself rule out misuse of third parties' rights, and sent the case back for evidence on how the campaign voice was generated and how similar it is to the actor's. The court docket shows the case back at first instance at the court-expert stage in 2025; no ruling on the merits is reported. Whether the AI voice reproduces the actor's voice is disputed.

The Civil Police of Brazil's Federal District (PCDF) say a criminal group manipulated the image and voice of TV presenter Marcos Mion with artificial intelligence in fraudulent videos promoting fake discounts at the Outback restaurant chain. According to the police, people who clicked the advertisements were sent to cloned websites and paid for discount vouchers that were never delivered. In January 2025 the police's first phase of Operation VoiceOver arrested three suspects; outlets relaying the police reported dozens of victims and 27 complaints in four days. A second phase on 9 May 2025 arrested a man in Santa Helena de Goiás who, police say, built and maintained the cloned sites and confessed his role. Every account relays the police; no outlet examined the videos, no tool is named and no individual victim or total loss is described.

Folha Vitória reported on 29 September 2026, citing the Espírito Santo Civil Police, that a 39-year-old man was arrested on 28 September on a preventive warrant after an inquiry into qualified theft by electronic fraud against an 81-year-old man in the north-west of the state. According to the police, the suspect, who worked as a security guard at a dance venue, invited the man to his home on the pretext of making a free-entry card, kept his bank card, obtained personal data and photographed his face. The police say he used the images to get past the facial recognition of the banking app and enable access to the account on his own phone, then reset security passwords, redeemed investments and made Pix transfers without the victim's knowledge, diverting R$6,080. The victim is described as illiterate. The police say the suspect had prior records and was serving a sentence under a progressive regime. Folha do ES and Tribuna Norte Leste carried the same police account but could not be read.

Three Mato Grosso do Sul outlets, all crediting BNC Notícias, reported on 10 April 2026 that a rural producer from Paraíso das Águas fell for the so-called Viva Sorte scam.

The Espírito Santo Civil Police (Defa, the fraud and forgery unit) said a 27-year-old man was arrested on a warrant in Serra on 22 September 2026, suspected of defrauding a personal trainer of more than R$100,000. According to the police, the suspect offered a car in exchange for the victim's motorcycle; during the negotiation he persuaded the victim to perform a facial-recognition procedure, saying it was needed to transfer the car's ownership; the biometric was later used to contract a vehicle financing in the victim's name without his authorisation, and weeks after the exchange the victim discovered that the car he had received did not belong to the suspect and was a rental. The loss, combining the motorcycle and the fraudulently contracted financing, exceeded R$100,000. The suspect, who police say had been arrested in São Paulo in July 2025 in a 'love scam' case, was taken to the Centro de Triagem at the Rodrigo Figueiredo da Rosa prison complex and remains at the disposal of the courts. The financing provider and the facial-recognition system are not identified, and the reports do not say how the captured biometric was used to pass the financing.

A businessman who owns a workshop in Campo Grande, Mato Grosso do Sul, found a car advertised at a market price by a seller who said he was in Ponta Porã, the businessman's home town; he passed his brother's contact so the brother could inspect the car. The fraudsters then contacted him as if they were his brother, saying he had seen the car, sending a video and confirming everything was in order; believing he was speaking to his brother, he made a Pix transfer of about R$28,000, after which the contact was blocked. He told G1 MS and TV Morena that the criminals used information about his family and a cloned voice. Guided by his wife, he contested the transfer through the Central Bank's special return mechanism and, after nearly three hours, a police report and an in-person registration, recovered about 20 percent. In a second case reported alongside, a medical student's mother in Dourados received messages, a voice note and a video from someone posing as her daughter, in a cloned voice, approving payment for an HB20 she was buying in Campo Grande; the mother checked directly with her daughter and discovered the audio had been AI-generated before any money was sent. A state prosecutor said his unit had not yet catalogued identical voice-cloning cases and urged victims to file police reports; the Civil Police did not respond to G1's questions. The date of the fraud is not reported.
