A 17-year-old boy was served an arrest warrant on Thursday on suspicion of breaching the server of a major internet cafe operator in Japan using a program generated by a conversational artificial intelligence, an investigative source said.The move comes after Kaikatsu Frontier Inc., the operator of Kaikatsu Club internet cafe and FiT24 fitness gym chains, suffered a cyberattack in January, with its parent company announcing the attack may have resulted in the leakage of personal information of 7.3 million customers.The high school student in Osaka is suspected of sending unauthorized commands to Kaikatsu Frontier's server some 7.24 million times to export personal data, thereby obstructing its business operations, the source said.Although AI services generally do not generate content that could be used for crimes, the student is believed to have concealed his true intention when prompting the AI.He had been arrested by Tokyo police in November for allegedly ordering a Pokemon card online using a third person's credit card information.
