It was discovered that an input form program developed by an IT company in Tokyo and introduced at multiple shopping sites, etc., was tampered with by someone, and that the information of at least 3,000 credit cards was leaked.
What was tampered with was an input form service program developed by the IT company "Showcase" in Minato-ku, Tokyo and introduced at shopping sites.
According to the company, in July this year, as a result of an investigation in response to complaints from business partners, it was found that the programs of three types of services had been tampered with due to unauthorized access from the outside.
At least 5,000 of these services have been introduced to various shopping sites, etc., and it is said that some of these sites may have leaked the information entered to the outside.
According to "ABC Mart", which sells shoes that used this service, about 2300 credits of users who used the input form on their site from July 24th to 26th. In addition to the possibility that card numbers and security codes have been leaked, 200 cases of "Ucan", more than 500 cases of "Fuji Film Imaging Systems", and "Idemitsu Credit" may have leaked credit card information. I am announcing that there is.
"Showcase" commented, "We deeply apologize for causing a lot of trouble to everyone involved."
