AI incidents

Reports of AI-related harm and adverse experiences affecting people’s safety, wellbeing, rights and livelihoods. Explore what happened and the evidence available.

NOPE’s core concern is when AI communicates with a person, acts on their behalf, or depicts or impersonates them. The tracker also records consequential decisions, claims and privacy harms involving AI. Each case needs a described connection between AI use and the harm, including private information recorded into or disclosed to an AI service. Each account is reviewed for publication; claims may remain uncorroborated or disputed. How we review and count cases

São Luís (Brazil): Federal Police arrest Bar exam candidate they say used a phone linked to an AI tool to cheat

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.

Brazil's Superior Court of Justice fines lawyers 20,000 reais over hidden commands aimed at AI in an appeal petition and refers them to the bar and prosecutors

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.

São Paulo court fines a defendant 9% of the case value over a hidden instruction in his defence asking AI to praise his lawyer

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.

Asturias court rules a security guard's 2023 dismissal unfair after a client replaced on-site guarding with AI cameras and patrols, La Razón reports

According to La Razón's account of a July 2024 judgment of the High Court of Justice of Asturias, Duro Felguera replaced the continuous on-site guarding provided by the contractor Protectum with a Securitas service that, from 1 August 2023, combined cameras with artificial intelligence for video analysis, roving patrols and alarm response. The guards of the outgoing contract were left out of the new one. Protectum ended a guard's employment on 31 July 2023. The court held that Securitas did not have to take him on because the new service was different, declared the dismissal unfair and ordered Protectum to pay him €30,672.72 in compensation plus processing wages. La Razón notes that human guards still intervened in the new service and that the presence of AI was part of the reorganisation without making the dismissal lawful.

Cases may have several effects and sources. Mixed accounts qualify when they include a reported harm or adverse experience. People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.

A source’s existence, the experience it reports and AI’s causal role are separate questions. A lawsuit records allegations unless a subsequent finding establishes them.
