日本京成电铁Skyliner预约系统遭非法入侵：最多约337万件顾客信息可能被获取，预约系统全面暂停
日本京成电铁11月13日宣布，连接成田机场与东京市区的特急列车「京成Skyliner」座位预约系统遭到第三方非法入侵，无票乘车服务的顾客信息可能已被获取，涉及件数最多约337万件。非法入侵发生在11月11日深夜，公司已全面暂停座位预约系统的使用，恢复时间未定。
京成电铁说，可能被获取的信息共五项：用户账号、密码、片假名姓名、电话号码和电子邮箱地址。公司表示，密码经过加密处理，第三方无法还原。公司将通过登记的电子邮箱逐一联系可能受影响的顾客；入侵的具体手法与原因尚未公布，实际被获取的件数也仍在确认中。
Skyliner是成田机场进出东京的主要交通方式之一。京成电铁已暂停Skyliner无票乘车服务、Skyliner e-ticket以及旅行社渠道的Skyliner车票销售，称此举是为加强系统安全；车站窗口和自动售票机仍可购票。

Keisei Skyliner Booking System Breached in Japan: Up to 3.37 Million Customer Records May Have Been Accessed, Bookings Suspended
Keisei Electric Railway announced on November 13 that the seat reservation system for its Keisei Skyliner airport express trains, which link Narita Airport with central Tokyo, had been illegally accessed by a third party and that customer information from its ticketless service may have been obtained, involving up to about 3.37 million records. The intrusion occurred late at night on November 11, and the company has suspended use of the entire seat reservation system, with no date set for its return.
Keisei said the information that may have been accessed covers five items: user IDs, passwords, names in kana, telephone numbers and email addresses. The company said the passwords were encrypted and cannot be decrypted by a third party. It will contact potentially affected customers individually at their registered email addresses. The method and cause of the intrusion have not been disclosed, and the number of records actually obtained is still being confirmed.
The Skyliner is one of the main ways to travel between Narita Airport and Tokyo. Keisei has suspended the Skyliner ticketless service, Skyliner e-ticket sales and Skyliner ticket sales through travel agencies, saying the step is intended to strengthen system security; tickets remain available at station windows and ticket machines.
