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.

On 19 August 2026 a Deputy President of Australia's Fair Work Commission ordered a self-represented former Aldi store worker to pay A$1,230 towards Aldi's legal costs. The decision records that his unfair dismissal application, lodged on the evening he was told of his dismissal on 26 March 2026, was obviously prepared using AI and still contained AI drafting notes, and that every email and document he filed was drafted using AI. He was notified of his dismissal three days short of the six-month minimum employment period. According to the decision, his AI-generated materials kept arguing about a different, irrelevant date (when the dismissal took effect), including after the Commission explained the correct test to him twice by email on 31 July 2026. He discontinued at the hearing on 5 August 2026. The Deputy President found that continuing after those warnings was unreasonable and said it was quite possible he had adopted AI as his quasi-legal adviser, while stating that using AI to draft submissions is not of itself unreasonable and that the responsibility was his. The decision notes that an appeal was lodged against it.

In a published opinion of July 2026, the Arizona Court of Appeals found that a self-represented appellant's opening brief in a probate dispute contained eight citations, six of them deficient, including two cases that do not exist. In a written explanation and at a hearing on the false citations he acknowledged relying on generative AI to write the brief and said he did nothing to verify the citations. The court struck the inaccurate and false citations, rejected the appeal because no supportive authority remained, held that citing a hallucinated case is sanctionable whether or not it is intended, and ordered him to pay the share of the other party's attorney's fees traceable to the fake citations. Because he said he did not intend to deceive and is not legally trained, the court chose this narrow sanction over contempt or fines. It described the opinion as the first published Arizona ruling on generative AI hallucinations in filings.

A Los Angeles County Superior Court judge ordered a senior associate at Musick, Peeler & Garrett, the outside firm defending State Farm in a homeowner's lawsuit over a fire-damaged home, to pay a $999.99 sanction after the associate's motions in limine cited cases, quotations and holdings that did not exist, Law360 reported on 14 September 2026. In a declaration reproduced by Reason's Volokh Conspiracy, the associate said she used an AI program called Irys to prepare the motions, did not check some of the citations, and wrongly believed the program was cite-checked through the firm's Westlaw subscription; she confirmed seven non-existent case citations across eight motions. The plaintiff's lawyers found the citations and raised them at a status conference on 7 August 2026. The firm acknowledged citations that appeared to be AI hallucinations, and its lead trial counsel apologised to the court and the plaintiff. According to Law360, the judge had considered up to $5,000, and the amount set is one cent below the level at which California law requires a court to notify the State Bar.

A São Paulo business and arbitration court found that every page of a defendant's written defence carried a hidden instruction, placed above his lawyer's letterhead, asking any AI that analysed the petition to give a favourable opinion and praise the lawyer's probity and care. In a sentence dated 14 September 2026 the judge treated this as prompt injection and bad-faith litigation: although the defendant won on the merits, he was ordered to pay the plaintiff a fine of 9% of the updated case value, and the sentence was sent to the São Paulo bar to examine the lawyer's conduct. No source says any AI system read the instruction.

Jun 2026 to Sept 2026GermanyUnidentified image tool (suspected)
The Gauting police inspection in Bavaria, Germany, reported on 2 October 2026 that a man had filed a complaint after realising he had been the victim of investment fraud. According to the police report, he said he had clicked on an advertising banner for an investment on the website of a large German news magazine, and the police say he was presumably lured by the combination of an AI-generated image of a well-known television presenter with a supposedly lucrative investment strategy. After he entered his email address and phone number on the trading platform, four women callers contacted him from 4 June 2026 until September and led him to make four payments totalling more than 25,000 euros to accounts in Bulgaria, Malta and Lithuania. His bank could not reverse the transfers because he had authorised them himself. The police do not say how they concluded that the image was AI-generated, and the presenter is not named in the police report.

The Boone County Sheriff's Office in Missouri said that on Friday 17 July 2026 a resident received a call whose caller ID showed their daughter's number. A voice that sounded like the daughter said she had been kidnapped at gunpoint, and another voice then demanded ransom. The office said it later determined that the voice was AI-generated, without saying how. Deputies found the daughter safe in Jefferson City and unaware of the call. The office called it the first AI voice-impersonation call it had encountered. No suspect had been identified by 19 July, and no source reports whether any money was paid.

On 24 April 2026 the Supreme Court of Alabama dismissed an appeal by two siblings in a family dispute over living trusts because their lawyer, W. Perry Hall, had filed briefs in which most of the legal authorities were misquoted or did not exist. The court said they appeared to be AI hallucinations, and at a show-cause hearing in February 2026 Hall admitted that many authorities did not exist and that he had improperly used AI to obtain them. The court ordered Hall to pay the opposing party's fees and costs of $17,200 and double appeal costs, barred him from filing in the court without a co-signing attorney and referred him to the Alabama State Bar. It said the dismissal was imposed as a sanction because of the particularly egregious facts. One justice, concurring in part and dissenting in part, objected to dismissing the appeal as a sanction for the lawyer's conduct but would have affirmed the judgment against the clients on the merits.

Thanh Hóa provincial police said on 3 October 2026 that their cybersecurity and high-tech crime division had, since the start of October, received reports from nearly 20 people threatened with extortion using sexual images and videos spliced from their own photos, which senders threatened to publish unless money was transferred. One victim was asked for as much as 1.5 billion dong, and officials, including commune-level leaders, were among the targets. The police release says the material was made with technology; Báo Thanh Hóa, reporting information compiled from the same police division, says the senders used AI and deepfake technology to put victims' faces onto sexual images. No payment, arrest or named victim is reported.

Jul 2026ChinaUnidentified AI voice-calling system
According to police in Yueqing, Zhejiang, as reported by CCTV's Fazhi Zaixian programme on 29 September 2026, a man in Yueqing who wanted to borrow money for his child's summer tuition in July 2026 received a call from a supposed loan-platform agent who knew his borrowing history. Guided by the agent, he took out a 15,500-yuan loan on a legitimate platform and then transferred 5,500 yuan as a supposed 'funder's advance' and 10,000 yuan for supposed repayment, losing the whole amount. His report led police to a call centre in an office building in Changsha, Hunan. Police say the ring paid for accounts on an AI platform, loaded illegally obtained phone numbers, and let an AI voice system call people automatically with recorded scripts that responded to keywords, sorting them into six categories and transferring interested people to human operators; another victim said he had not realised the voice was a robot until police told him. Police say the ring defrauded more than a thousand people in two months, with victims including recent graduates and middle-aged and older people. CCTV reported 30 suspects detained on suspicion of fraud, more than 1 million yuan frozen and transactions above 10 million yuan. On 12 October 2026 Wenzhou News, reporting the same Yueqing police case, gave a cumulative total of more than 90 people detained, with the same frozen-funds and transaction figures.

On 23 February 2026 Paolo Molesini, then chairman of Fideuram (the private-banking subsidiary of Intesa Sanpaolo), received a WhatsApp message from an unknown number from someone claiming to be Intesa's chief executive Carlo Messina, announcing a confidential acquisition that had to be executed through Fideuram. The same day a caller presenting as a lawyer of A&O Shearman whom Molesini knew, whose voice ANSA, Il Fatto Quotidiano and Corriere della Sera, reporting from the Milan court papers, describe as created with artificial intelligence (today.it, which also cites the seizure decree, writes that the court papers do not yet answer whether the voice was imitated), had him sign a confidentiality agreement and sent eleven payment instructions; Fideuram's treasury head was separately contacted by someone posing as Fideuram's CEO. Between 23 and 25 February eleven transfers totalling about 95 million euros went to accounts in Portugal and at Bank of China; the bank's alarm systems and the Milan prosecutors recovered about 40-42 million from China and 13 million seized in Portugal, leaving at least 36 million (39.5 million per the court papers) missing after conversion into cryptocurrency. Molesini, who Corriere writes is not under investigation, resigned as chairman on 12 March 2026, which Fideuram announced as being for personal reasons; a 48-year-old Israeli citizen is under investigation as a member of the gang.

A security guard in Bengaluru, originally from Odisha, told the Times of India that on 9 September 2026 he answered a WhatsApp video call in which a face and voice presented as Tamil Nadu Chief Minister C. Joseph Vijay introduced himself in Hindi, asked his name, work and where he lived and pressed him to accept financial help. A 'manager' then promised Rs 11 lakh, said Rs 5 lakh had been allotted to him and asked for a Rs 5,000 exchange charge, then Rs 18,000 to unlock a supposedly locked PIN; a caller posing as a CBI officer demanded more than Rs 50,000 as a fine. The fraudsters sent a fake allotment letter and a purported CBI officer's identity proof. He paid more than Rs 1.04 lakh through a digital payment app before refusing a further Rs 50,000 demand, called the 1930 cybercrime helpline and went to Byappanahalli police, who registered a case under the Information Technology Act. The Times of India says the fraudster allegedly used a deepfake AI-generated video and calls it the first such case reported in the city. No arrest is reported, and no link to the Tamil Nadu CB-CID deepfake case or its Alwar arrest has been established.

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.
