19 Jun 2026 to 13 Aug 2026BrazilChatGPT
A man in Brazil was held in pre-trial detention for 54 days in 2026 after OpenAI’s safety systems flagged his ChatGPT conversations and the company reported them to the FBI, which alerted Brazilian police. Police say the messages described a threat to a family member; he denies that intent and his lawyer says he only talked nonsense to the chatbot. A court released him on 13 August under precautionary measures; no charges had been filed as of mid-September. OpenAI did not give police ChatGPT’s replies.

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.

On Monday 10 August 2026 a digital influencer from Picos, in the centre-south of Piauí, began negotiating a car advertised online for sale in Fortaleza (Ceará), where an uncle of his lives, and asked the sellers to take the car to the uncle so he could inspect it. On Tuesday 11 August a contact using a different number but the uncle's photo sent him audio messages in a voice identical to his uncle's, generated with artificial intelligence, saying the car was in good condition and telling him to make the bank transfer. Believing he was speaking to his uncle, he transferred the money; when he then called the uncle's real number he learned he had been defrauded. The loss exceeded R$56,000, money he says he had saved for years. He registered a police report on 11 August; the Piauí property-crimes unit (Depatri) is investigating and he is seeking a refund from the banks. The account is the victim's own, reported by G1 Piauí on 13 August 2026 from his social-media posts and an interview; the police unit did not respond to G1 before publication.

On 14 July 2026 the Rio Grande do Sul Civil Police launched Operação Sophia against a group that used AI voice cloning and deepfake to turn real fundraising campaigns of children with cancer into fake donation appeals: AI-generated child voices asked for money in videos boosted by pages such as 'Clube de Doadores' and 'Unidos pelo Amor', leading donors to lookalike sites that issued Pix codes to shell companies. Sixteen people were arrested across five states. In the campaign that started the investigation — using the image of Kelen Santos's daughter, who was in cancer treatment — police traced R$294,500 diverted, and the investigation found a financial-hub company that moved more than R$1.7 million. The family had to tell congratulating donors that their money had gone to a scam.
