Artificial intelligence is increasingly supporting software development, education, and business operations. At the same time, cybersecurity experts and law enforcement agencies have warned that generative AI tools can also be misused to automate unlawful activities. A recent cyberattack involving Japan’s Bandai Channel has renewed debate over this issue after investigators alleged that a teenager used ChatGPT to help develop an automated attack script.
The case has drawn international attention because it highlights broader concerns about AI-assisted cybercrime and the growing involvement of young offenders in sophisticated digital offences. While the investigation is specific to Japan, experts say it illustrates the need for responsible AI use, stronger cybersecurity practices, and continued digital ethics education.
Bandai Channel Cyberattack: Confirmed Facts
According to Japan’s Metropolitan Police Department, as reported by JAPAN Forward and The Times of India, a 15-year-old high school student from Tokorozawa, Saitama Prefecture, was arrested in connection with a cyberattack targeting Bandai Channel, an anime streaming platform operated by Bandai Namco Filmworks.
Police allege that the attack occurred on 4 November 2025 and resulted in the unauthorised deregistration of approximately 46,812 subscription accounts. This figure is based on police statements reported by Japanese media and retrieved from published reports in July 2026. Bandai Channel temporarily suspended parts of its service while investigating the incident and later restored normal operations.

Alleged Use of AI
Investigators allege that the student had independently studied programming from an early age and analysed the platform’s server traffic to identify potential vulnerabilities.
According to police statements cited by media reports, the teenager allegedly used ChatGPT to assist in creating an automated script capable of sending repeated requests to the company’s servers. Authorities claim the program transmitted false data that disrupted account records.
Investigators further allege that proxy servers were used to repeatedly change IP addresses after network restrictions were introduced, enabling the activity to continue despite defensive measures. These allegations remain subject to Japan’s judicial process.
Investigation and Legal Context
The Metropolitan Police Department’s Cybercrime Division arrested the teenager on 4 July 2026, describing it as the second arrest linked to the broader investigation.
Authorities also stated that the student had previously been arrested in June 2026 for alleged violations of Japan’s Act on the Prohibition of Unauthorized Computer Access, involving unauthorised access to user account information.
As of 9 July 2026, no final court judgment has been reported. The allegations remain under judicial consideration, and any future court findings or official statements may provide additional details.
Why the Case Matters
Research published by Europol, the National Crime Agency (UK), and the International Journal of Indian Psychology (IJIP) suggests that some juvenile cyber offenders develop advanced technical skills through self-directed learning and online communities. Studies also indicate that technical curiosity, when combined with limited awareness of legal consequences, can contribute to risky online behaviour.
Importantly, researchers emphasise that an interest in programming does not predict criminal behaviour. Most young people with cybersecurity skills pursue education, research, or careers in legitimate fields.

AI and the Evolving Cybersecurity Landscape
Cybersecurity specialists note that generative AI can assist with coding, debugging, and automation. While these capabilities have legitimate uses, they may also reduce the technical effort required to create automated tools if misused.
Experts, including cybersecurity researcher Bruce Schneier, recommend shifting from traditional perimeter-focused security to behavioural monitoring. Frameworks such as Zero Trust Architecture, which continuously verifies users and devices, and Network Detection and Response (NDR), which identifies unusual network activity, are increasingly recommended to strengthen cyber resilience.
Broader International Perspective
The Bandai Channel investigation reflects a wider international trend. Reports published by Europol and other law enforcement agencies have documented the involvement of teenagers and young adults in several high-profile cybercrime investigations. Experts therefore recommend combining enforcement with education, ethical hacking programmes, cybersecurity competitions, and responsible vulnerability disclosure initiatives to encourage legal pathways for technically skilled young people.
Cyber Safety Advisory
- Download software and cybersecurity tools only from trusted or official sources.
- Never run unknown scripts or applications obtained through unofficial forums or messaging platforms.
- Do not share passwords, one-time passwords (OTPs), or authentication codes with anyone.
- Verify suspicious emails, payment requests, or technical support messages before responding.
- Report suspected cybercrime to the appropriate national cybercrime reporting authority. In India, incidents can also be reported through CERT-In and the National Cyber Crime Reporting Portal.
