OSAKA (Kyodo) Hackers stole customer data from eight online supermarkets in Japan, including Uny Co. and Neo Beat Co., in July using a hacking technique called SQL injection to access their databases, sources said.
A source close to Neo Beat, which also operates the Web sites of the online supermarkets, said Friday it believes the approximately 30,000 unauthorized accesses to its database server were likely "perpetrated by a group of professional hackers."
The accesses, which were conducted from Japan and China from July 24 to 26, resulted in the theft of data on 12,191 customers of the Osaka-based company as well as its seven business partners, including supermarket chains Izumiya Co., Maruetsu Inc. and Ryukyu Jusco Co.
