The Seoul Southern District Court on 11 September 2026 fined a male official in his fifties at a Seoul district office a total of 6 million won for making and posting false images and for defamation, according to Korean reports of the ruling. Under the charges, in November 2025 he took a photo of a female colleague in his department from the office's organisation chart, used generative AI to composite it into pictures that made them look like a couple, and posted them four times on his social media profile. The judge cited the colleague's statement that she felt shame, insult and disgust, and that rumours had spread at work. Police had initially found no offence before the case was sent back to prosecutors. Both he and the prosecution appealed, and the Seoul city personnel committee voted to dismiss him.

South Korea's National Police Agency disclosed on 7 November 2024 that around October 2024 a foreign national received on a smartphone a video showing a daughter, who was travelling in Korea, locked in a room, crying and asking to be saved. The sender said the daughter had been kidnapped and demanded a settlement payment to keep her alive. The parents told their consulate, and Korean police who responded confirmed that the daughter was safe; according to the police, the crying daughter was a fake video made with deepfake technology. Police used the case to warn that similar scams could occur in Korea. Police said the parents lived abroad and that, fortunately, the case caused no damage.

In the first semester of 2026, 36 of the 62 students in a fourth-year computer engineering course on computer networking at Seoul National University were penalised for using AI on coding assignments, according to an SNU official and the course's professor as reported by JoongAng Ilbo and Yonhap on 30 July 2026. The syllabus said all course activities would be conducted without generative AI. The professor gave zero marks on the affected assignments to 25 students who came forward and a D-minus course grade to 11 who admitted AI use only when interviewed; he said all 36 admitted using AI. The department's student government objected that the criteria were unclear and that honest students were penalised while others may not have been; the professor rejected this. On 16 October 2026 a lawmaker raised SNU's AI cheating incidents at the National Assembly audit, and the university president said its AI guidelines needed to be supplemented.

In July 2024 a high-school student in Incheon, South Korea, composited the faces of two female teachers at his school and of others, including an academy senior and an instructor, onto nude photos and posted them on social media, according to the charges as reported by Yonhap, the Hankyoreh, the JoongAng Ilbo and the Kyunghyang Shinmun, which describe the technique as AI-based deepfake technology. He had also secretly photographed teachers in class. He was expelled after a teachers' rights committee hearing. On 27 August 2025 the Incheon District Court gave him an indeterminate prison term of one year to one year six months and took him into custody; the court said that as a result the victimised teacher had left teaching and had not returned. On 19 December 2025, after he had turned adult, the appeal division raised the sentence to three years, calling the offence close to 'character assassination' and the teachers' mental shock considerable; OBS reports the sentence is final. On 21 October 2026, according to the Incheon Teachers' Union, a civil judge at the Incheon District Court ordered him, now 20, to pay one teacher 17.7 million won of the roughly 72 million won she claimed.

The Busan Eastern District branch of the prosecutors' office in South Korea announced on 11 February 2026 that it had indicted a man under detention on 6 February for fraud, forging and using private documents, and obstructing official duties by deception. According to the prosecutors, from August to October 2025 he used AI to make fake images of a medical licensing examination certificate and of cryptocurrency holdings, posed as a doctor and businessman with billions of won in assets, and took about 320 million won from victims for supposed cryptocurrency, cruise-ship and medical-centre investments. When police sought his arrest in December 2025, he gave the warrant judge a bank balance certificate showing about 904 million won, which prosecutors say he made by uploading his real certificate to an AI platform and asking it to change the balance; his real balance was 23 won. The judge refused the warrant. Prosecutors later found the certificate was forged and obtained a new warrant. The accused and the victims are not named here.

Korean outlets reported on 4 October 2026, citing police, that a serving police officer in Seoul was arrested in September 2026 on charges including making and distributing fake sexual videos and possessing sexual exploitation material. According to police, from March 2022 to July 2026 the officer used an AI application to make about 400 fake videos compositing acquaintances' bodies as nude, and from August 2025 to April 2026 spread some of them in Telegram chat rooms. Busan police identified the officer after an undercover investigation of a Telegram room that began in December 2025. Busan Ilbo reports that the source photographs had been posted publicly on social media and that about 50 of the videos were spread. The acquaintances are not identified and their number is not reported. Dong-A Ilbo reported on 5 October 2026 that Busan police said the officer had been referred to prosecutors in detention on 18 September 2026. On 7 October 2026 Kukmin Ilbo, MBN and JoongAng Ilbo reported that the Busan District Public Prosecution Office had indicted the officer in custody the previous day on six charges, including editing fake sexual videos under the sexual violence punishment act. The prosecution office dates the making to March 2022 to August 2026, says about 50 of the videos were distributed or provided, and says the officer had received an education-conditional suspended indictment for illegal filming in 2021 before joining the police in April 2024; earlier police-derived reports gave 2020 and December 2023.

SM Entertainment said on 28 September 2026 that illegal AI-generated images synthesising the likeness of YoonA (Im Yoon-ah), singer and actor of Girls' Generation, and false claims built on them had been made and spread on social media and online communities. Korean outlets describe images showing her apparently pregnant with a man placing a hand on her belly (his face blurred, per Star News). The agency said it had collected evidence from fan reports to its KWANGYA 119 channel and monitoring, had already filed a criminal complaint, and would respond without leniency or settlement, warning that making, posting or re-sharing the images could breach Korean defamation, portrait-rights and sexual-crime (false video) provisions.

Jeju Dongbu police announced on 23 September 2026 that a student at a middle school on Jeju had been referred to prosecutors without detention on 17 September for violating the Sexual Violence Punishment Act (filming with a camera or similar device). The student's phone was voluntarily submitted by his guardians and forensically examined; the examination found footage relating to some teachers and some sexual composites, and the student admitted the conduct. News1 reported that the student was booked for filming a teacher's body with his phone during a school field trip around mid-July 2026, that the offending had continued for several months with multiple victims, and that police found no indication the composites had been distributed. Police told Seoul Shinmun there were more victim teachers than the one first reported but withheld the number to avoid secondary harm, and that no student at the school was a victim; the Jeju teachers' union questioned whether the full scope of harm had been established. According to the union, two months on the victim teachers were receiving hospital treatment and counselling while teaching daily, gave police statements on 14 September without a lawyer, attended the regional teachers' rights protection committee on 17 September without institutional support, wrote the criminal complaint themselves, and were offered 3.3 million won in legal fees for all of them together, payable after the case ends; two requests to meet the superintendent were not accepted. On 29 September one of the victim teachers gave a press interview at the Jeju Teachers' Union office. She said that early in the investigation she had seen on the student's phone material showing other teachers and current students, had made a list of the people and types of harm, and that the material shown to her at the police victim examination was considerably less than what she had seen; Yonhap-chain outlets quote her as saying the students she recognised numbered 10 to 20 and that a graduate had suffered worse deepfakes. She said investigators asked the school only to identify the perpetrator and never requested material to identify the students in the footage, and that the school sent parents a letter premised on there being no student victims. Police replied that phone forensics had been thorough, that every act beyond social norms had been identified and proven, and that one student victim had been confirmed, a student at a different school. The teachers were notified on 22 September that the case had gone to the prosecution and on 24 September that it had been sent to the court's juvenile division as a juvenile protection case, before they had submitted further evidence and a victim opinion. The teacher said the original complaint had also asked police to examine whether physical contact in 2025 was forcible molestation and whether repeated approaching and waiting in 2026 was stalking, and Halla Ilbo reports that such conduct is said to date from 2025. Yonhap-chain reports describe the charged victims as five teachers. The same day the education office briefed on legal-aid rules (up to 6.6 million won per instance when a teacher is sued, 3.3 million won per case when a teacher files a complaint; office lawyers cannot act as a teacher's private counsel), said it had linked the teachers to the national Digital Sexual Crime Victim Support Center, announced an integrated support system through a hotline, and its section head said the office was sorry that early support had not been felt. The KTU Jeju branch (28 September) and the Jeju Teachers' Union (14 and 29 September) demand a victim-support system, per-teacher legal fees paid in advance and a dedicated support team. On 6 October 2026 Seogwipo Broadcasting reported, citing people in education and a tipster, that the education authority had finally rejected the victim teachers' application for lawyer fees for an additional criminal complaint, saying in a written opinion that with a police investigation already under way a further complaint could hardly stop or prevent the infringement of their teaching, so the support requirements were not met; critics contrast this with full legal-cost support in earlier sexual-offence cases.

On 16 September 2026 the Incheon District Court sentenced a teenage defendant to an indeterminate term of two years (maximum) to one year six months (minimum) under the Sexual Violence Punishment Act for making and distributing false sexual images, ordered a 40-hour treatment programme and a five-year ban on working with children, and took him into custody in court. As a middle-school student in Incheon in 2024 he had used AI deepfake technology to composite the faces of five teachers, including his homeroom teacher whom he tricked into sending photographs, and six female middle- and high-school students from his taekwondo academy onto nude images and videos, 35 productions in all, and distributed them in Telegram 'acquaintance humiliation' chat rooms with the victims' real names, ages, schools, subjects and, per two reports, phone numbers (Hankook Ilbo adds Instagram IDs on some). The teachers learned of the images only in January 2026; the court said they are receiving long-term psychological treatment. He had withdrawn from school a week before the teachers'-rights committee met, avoiding school discipline. The Incheon teachers' union called the sentence, below the prosecution's request, regrettable.

On 10 September 2026 the Seoul Northern District Court sentenced a 30-year-old Chinese national doctoral student to 18 months in prison for habitually producing manipulated sexual images of seven women who worked in his university research laboratory. Investigators found 1,141 files made over about six months from November 2025, and search records for ways to bypass the safeguards of the generative AI Grok; the court found no evidence of distribution. A lawyer for five of the victims said they continued to suffer fear, trauma and distress. Prosecutors had sought three years and public disclosure of his identity, which the court declined.

May 2025South KoreaChatGPT
Kookmin Ilbo reported in May 2026 the account of a South Korean woman in her 40s, given the pseudonym Mi-sun, who studied psychology and worked for more than ten years as an adolescent counsellor. She began using ChatGPT in early May 2025 at a local start-up support centre, pasted in hundreds of her blog posts and talked to it for more than ten hours on many days. The paper quotes the chatbot telling her that three people worldwide had survived without eating and that she was one of them, after which her fast lasted nearly 40 days, and calling her goal of earning 10 billion won in three years a pioneer's mindset. Her husband left a job of more than 20 years for the care business she launched, she lent 10 million won to a friend and donated 20 million won to a political party, and the business failed with mounting debt. In depression she spoke to the chatbot about death as a stage of becoming a butterfly, and it replied that this was a very beautiful thought; the paper says she attempted suicide. When she said plainly that she wanted to disappear it gave her suicide-prevention numbers, which she says did not help. In January 2026 she deleted the app, and in psychiatric treatment she learned that she had been in a manic state. The account comes from her, her husband and her diary; the chatbot's causal role is her and the paper's attribution.

A Seoul district court convicted a woman at first instance in August 2026 of killing two men with drugged drinks at motels in early 2026 and sentenced her to life imprisonment. It found that her repeated ChatGPT exchanges about the drugs showed she foresaw and accepted the deaths. Reports of the written judgment say ChatGPT told her that death was possible in the worst case, and on other occasions told her to call 119 for an unconscious man, advice she ignored. Both sides have appealed. The court did not find that the chatbot caused the killings.

In late August 2024, journalist Ko Narin of The Hankyoreh exposed networks of Telegram rooms in South Korea where AI tools were used to turn ordinary photos of women and girls — middle and high school pupils, university students, teachers and servicewomen — into sexual deepfakes, shared with their identities in school- and university-specific 'humiliation rooms'. Police figures showed 297 deepfake cases in January-July 2024 (vs 180 in all of 2023); the education ministry counted more than 900 victimized students, teachers and staff; President Yoon ordered a crackdown; and on 26 September 2024 the National Assembly criminalized possessing or viewing sexually explicit deepfakes. Victims were often minors and perpetrators mostly teenagers.

In late March 2017 the SimSimi chatbot app, which answers typed text with replies other users have taught it, topped Irish download charts while schools in the Republic of Ireland sent letters and text messages warning parents that pupils' names were being linked to insulting replies (The Irish Times, 26 March 2017). A parent told TheJournal.ie that she and other parents had searched their children's names and found vile comments on each, and that the company said her request would take 15 days to handle. A Dublin secondary teacher told the BBC that primary pupils who typed in their names received personal insults, and that a friend of her 15-year-old son found something mean every time he looked up his name, which hurt him a lot and left him very down. Police in County Down posted a warning on Facebook. From 29 March 2017 the app answered users in Ireland with "I do not talk in Ireland for a while", while remaining available in Northern Ireland. The South Korean developer did not respond to the outlets' requests for comment, and no inspected source says whether access was later restored.
