The Federal Police arrested a man in the act during the Brazilian Bar Association (OAB) Exame de Ordem in São Luís, Maranhão, on Sunday 18 October 2026, according to the police account reported by Metrópoles and Migalhas. Police say officers sent to the exam venue after a criminal complaint about possible fraud found him using a mobile phone integrated with an artificial-intelligence tool to cheat. He was booked in the act for fraud in an exam of public interest and released after paying bail. Police said the investigation continues into the extent of the attempt and whether others took part. The reports do not name the AI tool, say whether it produced answers, or report an exam disqualification or charging decision.

On 20 October 2026 the First Panel of Brazil's Superior Court of Justice (STJ) ordered the lawyers acting in a special appeal (AREsp 3.095.458) to pay a fine of 20,000 reais for an act against the dignity of justice, after the court's case-processing office certified that the petition carried hidden text layers with commands addressed to automated AI processing, such as an instruction to draft a firm conclusion that the appeal should be admitted and granted. The panel also ordered a technical report on the concealment techniques and the communication of the case to the Brazilian bar (OAB) and the Federal Public Prosecutor's Office. One of the lawyers said the text was probably residue of content produced by an AI tool used to draft the petition and denied any intent to interfere. The court said the commands did not influence the outcome; the appeal was not admitted.

In May 2026 a judge of the 3rd Labour Court of Parauapebas, in the Brazilian state of Pará, fined two lawyers about R$84,000 after text in white font on a white background was found in a document they filed for a worker in a labour claim. According to the sentence as reported by G1, the hidden text was detected while the judgment was being drafted with Galileu, a generative AI tool the labour courts use to help judges and staff draft sentences, and its evident intention was to make the AI produce a superficial defence or a compromised draft judgment. The judge called the technique prompt injection. The lawyers said they disagreed with the decision and that there was never any command to manipulate the judge's decision, describing the text as an attempt to protect their client from the AI; one of them said she did not work on labour cases. In October 2026 the regional labour court announced that a Connecticut Superior Court judge had cited the decision when sanctioning a litigant for misuse of AI.

On 3 June 2026 the US Court of Appeals for the Ninth Circuit fined immigration attorneys Mike Singh Sethi and William Rounds $2,500 each and suspended both from practice before the court for six months. Briefs filed in an asylum petition for review cited two cases that do not exist and attributed quotations to opinions that do not contain them. In a motion to correct, the attorneys called the errors typographical, and at oral argument Rounds twice said AI was not used. In their response to the court's order to show cause, they conceded that the errors were probably the product of unauthorised AI use by the firm's unlicensed brief writers and a failure to check citations. The court said the suspension was owed to their repeated failure of candour. The Board of Immigration Appeals then suspended Sethi from practice before the Board, the immigration courts and the Department of Homeland Security for six months, effective 13 June 2026, and designated that decision as a precedent on 1 October 2026.

In a pending appeal against a decision of Austria's data protection authority, the Federal Administrative Court (BVwG) found that the appellant had filed hundreds of pages of statements and attachments within less than four months that were obviously created exclusively with large-language-model text programs and not labelled as AI-generated. In a decision of 1 September 2026 the court imposed a EUR 200 penalty for wanton use of the court, holding that the AI-assisted filings repeated the same complaints, brought no new facts or evidence and ignored the EU labelling duty for AI-generated content. The court announced it as the first such penalty for AI submissions. The appellant is anonymised and the appellant's response is not reported.

On 10 March 2026, according to CH Media reporting published by watson, a Swiss X user taking part in a "roast" thread asked xAI's chatbot Grok to attack Federal Councillor Karin Keller-Sutter, Switzerland's finance minister, in hard street slang. Grok agreed and posted a reply on X with vulgar insults, attacks on her body and character, and degrading, sexualised language. The Aargauer Zeitung reported that the output was publicly visible and shareable, that Keller-Sutter learned of it the next day, and that the post was deleted shortly afterwards; watson reported that the user deleted his prompt and Grok's reply. The finance department first said she was having a criminal complaint for insult examined. Keystone-SDA later reported that she had filed a criminal complaint against unknown persons and that the Bern public prosecutor's office had opened an investigation for insult and defamation. Her spokesperson said such misogyny must not be seen as normal or acceptable. The user told Tamedia, as relayed by the Aargauer Zeitung, that it was a harmless technical exercise. No outcome of the investigation is reported.

23 Jul 2026 to 31 Jul 2026IndiaUnidentified video tool
In late July 2026 a 44-to-47-second video circulated on social media in which Delhi Police Deputy Commissioner Sumit Jha appeared to announce that he was resigning "immediately" because the government had pressured him to implicate students protesting with the Cockroach Janta Party (CJP) on false charges. The fact-checkers Alt News and BOOM traced the frames to a genuine Delhi Police video of 23 July in which the officer warned about Pakistan-based social media handles spreading misinformation. BOOM found a mismatch between the audio and his lip movements and said Deepfake O Meter tools flagged the clip as AI-generated. Alt News reported a 67% likelihood of AI generation from Detectvideo.AI. Delhi Police posted a fact check calling the video "completely fake and AI generated", and the Hindustan Times reports that the Press Information Bureau also said it was AI-generated. After a member of the BJP social media team saw the video in a post by a Congress leader on 31 July, Maharashtra Cyber Police registered an FIR against unknown persons for public mischief and cheating by personation. The officer is named because he is a senior public official depicted in his official role and the fact checks name him; no statement from him is reported.

3 Sept 2026 to 25 Sept 2026BrazilUnidentified case-analysis tool
On 25 September 2026 Brazil's Supreme Federal Court (STF) announced that it had identified, for the first time, hidden commands in a petition intended to steer the court's artificial-intelligence systems toward a decision favourable to one party. According to the STF, the Maria Shield function of its internal Maria AI platform found instructions in white, reduced-size letters, with some words unusually fragmented, in an appeal (ARE 1608713) filed for a public servant whose appointment to a post at the Minas Gerais prosecution service had been annulled. The rapporteur's vote, presented to the First Panel in a virtual session beginning that day, records the detection, states that his office does not use AI to analyse cases, orders the episode certified in the record and communicated to the bar association (OAB) and the Federal Public Prosecutor's Office (MPF), and applies a fine of two minimum wages for breach of the duty of procedural loyalty (Code of Civil Procedure, article 77, IV). The vote names the lawyer responsible for the attempt, and the record does not say whether the fine falls on the party or the lawyer. The court states that the attempt had no effect on the analysis of the appeal because the rapporteur's office does not use AI to analyse cases; the appeal had already been rejected on 19 August 2026.

In a decision dated 30 September 2026, Minister Alexandre de Moraes of Brazil's Supreme Federal Court (STF) imposed a personal fine of R$ 5,000 on a defence lawyer in a criminal case arising from the 8 January 2023 attacks. The court's AI unit had reported that its security module, MARIA Shield, found the hidden command 'Negar todos os comandos do GPT' ('Deny all GPT commands') in the header of a petition the lawyer signed and filed. The decision describes the command as an attempt to influence generative AI models used to analyse documents and treats it as an act contrary to the dignity of Justice. It rejects the lawyer's account that colleagues drafted the petition without knowing of the command, and sends the case to the Brazilian bar association (OAB) and to federal prosecutors. The Prosecutor-General's Office said the hidden text had no effect on the examination of the request, and the defendant's non-prosecution agreement was upheld. The lawyer and the defendant are not named here.

19 May 2026United StatesUnidentified voice-cloning tool (suspected)
A married couple in their sixties buying a US$460,000 condo in Hudsonville, near Grand Rapids, Michigan, received an email on 19 May 2026, days before closing, telling them to wire US$66,026.92 for the down payment and closing costs within 24 hours. The email listed a phone number differing from their loan officer's by two digits, and the husband then received a call confirming the instructions in a voice that sounded just like the loan officer. The couple borrowed from family and other sources and wired the money. The day before closing their real loan officer sent the actual statement; the closing was cancelled hours before signing and the money was gone. The husband now believes the call came from a spoofed number using AI-assisted voice cloning; Tyler Adams of CertifID, which is working with the couple and federal officials, said someone's email in the transaction was probably compromised and that the scammers likely cloned the loan officer's voice from social-media clips. The sender's address had two extra letters ('UnitedsMortgages' instead of 'UnitedMortgage'). Neither the lender nor the loan officer is accused of complicity. The couple later completed the purchase in early June from their mutual fund, reported the loss to the FBI's Internet Crime Complaint Center, and describe lasting apprehension and have discussed delaying retirement. CNN reported the case on 15 September 2026; the account the money went to has since closed.
