BEIJING--Stacks of in-house documents from some of the biggest names in corporate Japan have turned up on a Chinese document-sharing site, despite recent efforts to prevent leaks of confidential information.
Toyota Motor Corp., Honda Motor Co., Sony Corp. and Hitachi Ltd. are among the companies targeted.
Internet users can download the documents from Baidu Wenku, operated by Chinese search engine provider Baidu Inc.
The documents were apparently leaked by Chinese employees of the companies or business partners.
Yusuke Wakebe, a lawyer based in Shanghai, said companies began fighting back late last year with dramatic results. New leaks soon dropped.
Honda, Hitachi and other companies ask Baidu to delete in-house documents as soon as they are found on the site.
The documents uploaded on Baidu Wenku include organization charts, management plans and detailed sales data. None of the documents had previously been disclosed to outsiders, and some were marked “for internal use only” or “confidential.”
Among the documents found on the site were an agency’s advertisement strategy proposal to a Chinese company, an electronics maker’s report on staff turnover and a manufacturer’s technical document apparently for a patent application.
A person who uploads a document on Baidu Wenku receives “points” based on the number of downloads made, which can then be used for downloading other documents.
As Chinese businesses are interested in Japanese companies’ management, technology and training methods, those who leaked the in-house documents apparently wanted to score points by uploading sought-after information.
