In February 2026, Lake Zurich High School administrators were alerted that students had used AI to generate sexually explicit images of female classmates. The school district notified the police, who launched an investigation into the potential transmission of lewd material involving minors. The incident impacted numerous students and prompted school-based disciplinary actions and targeted support for the affected community.
In February 2026, administrators at Lake Zurich High School in Lake Zurich, Illinois, a northwest suburb of Chicago, reportedly received a complaint that students had used AI to generate explicit images using classmates' likenesses. The district reportedly notified police and affected families. Police described an active investigation into possible transmission of lewd AI-generated material depicting juveniles.
Domain classification, causal taxonomy, severity scores, and national security assessments were LLM-classified and may contain errors.
Using AI systems to gain a personal advantage over others such as through cheating, fraud, scams, blackmail or targeted manipulation of beliefs or behavior. Examples include AI-facilitated plagiarism for research or education, impersonating a trusted or fake individual for illegitimate financial benefit, or creating humiliating or sexual imagery.
Also classified as
The AI was used to generate child sexual abuse material (CSAM) and explicit pornographic content of minors, exposing the community to highly toxic and illegal material.
The incident involves the targeted creation of humiliating and sexual synthetic imagery of specific victims (classmates) for personal amusement or harassment, which fits the boundary rule for targeted exploitation under 4.3.
Human
Due to a decision or action made by humans
Intentional
Due to an expected outcome from pursuing a goal
Post-deployment
Occurring after the AI model has been trained and deployed
The harm was caused by students intentionally misusing a deployed AI image generation tool to target and humiliate their classmates.
Added categories peak at 3: Substantial (Child Sexual Exploitation & Abuse (CSEA), Direct)
High school students in Illinois used generative AI to create non-consensual sexually explicit images of over 40 female classmates. While representing a severe local law enforcement issue and privacy violation of minors, the incident has negligible direct national security implications and is being managed by local school district authorities and police.
The AI system was used as a tool by students to perform a specific function (generating images based on direct inputs and likenesses) without autonomous planning or agency.
Risk Level 3: Limited Risk. The incident involves the use of AI to generate deepfakes (explicit images using the likeness of others), which falls under transparency obligations for AI-generated content.
The AI system was used to generate explicit, pornographic images using the likeness of other adolescents, which is the definition of deepfake image generation.
The report provides clear and detailed accounts of the incident, including the number of victims, the actions taken by school administrators and police, and the specific nature of the AI misuse. The lack of the specific AI tool name does not prevent a high-confidence assessment of the risks and harms.
None. The report is unambiguous about the misuse of AI to generate explicit images of classmates.
