东京警视厅逮捕一名31岁中国籍男子：涉嫌在银座等地用车载伪基站干扰通信、两小时内影响逾万部手机并发送钓鱼短信
东京 — 日本东京警视厅近日以涉嫌违反《电波法》逮捕31岁的中国籍无业男子于海，指控他把无线电设备装在车内、在东京繁华街区非法开设电台，并涉嫌干扰重要无线电通信。据日本媒体11月9日报道，这是日本首次查获车载式「伪基站」案件。
警视厅说，于海涉嫌从车内发射强力电波，先阻断周边的4G与5G信号，再以所谓的「伪基站」迫使半径约500米内的智能手机连接2G网络，随后向这些手机发送钓鱼短信。短信以中文写成，声称用户的应用账号出现问题、将被停用等，诱导收信人进入钓鱼网站输入信用卡号等个人信息。
据警视厅通报，于海开车在银座、新宿、涩谷一带活动，不到两小时就影响了超过1万部智能手机。过去约两年里，警视厅陆续接到18人报案，其中包括中国游客，称在购物时收到这类短信、登记信用卡号后出现不明扣款，已知损失约400万日元；警方认为这只是冰山一角，背后可能涉及有组织犯罪，正继续追查全貌。
于海在讯问中否认指控。警视厅是在银座四丁目路口一带将其当场抓获的。

Tokyo Police Arrest a 31-Year-Old Chinese National Suspected of Running a Car-Mounted Fake Base Station Across Ginza, Shinjuku and Shibuya, Forcing Over 10,000 Phones onto 2G and Sending Phishing Texts
TOKYO — Tokyo's Metropolitan Police Department has arrested Yu Hai, a 31-year-old unemployed Chinese national, on suspicion of violating Japan's Radio Act by operating a radio station without a license from equipment mounted in his car, and of interfering with important radio communications. Japanese media reported on November 9 that it was the first arrest in Japan involving a vehicle-mounted "fake base station."
Police say Yu allegedly transmitted powerful signals from his car that knocked out 4G and 5G service nearby, then ran a so-called fake base station that forced smartphones within a radius of about 500 meters to connect to a 2G network, after which phishing text messages were sent to those devices. The messages, written in Chinese, claimed there was a problem with the recipient's app account and that it would be suspended, directing them to phishing sites designed to harvest credit card details.
Yu drove around the Ginza, Shinjuku and Shibuya districts and affected more than 10,000 smartphones in under two hours, police said. Over the past two years the department has received reports from 18 people, including Chinese tourists, who said they received such a message while shopping, entered their card numbers and were then charged for purchases they did not make; known losses total about 4 million yen. Police believe that is only the tip of the iceberg, suspect organised crime behind the operation, and are investigating its full extent.
Yu, who was arrested on the spot near an intersection in Ginza 4-chome, has denied the allegations in questioning.
