Sanrio Digital notifies that personal information belonging to members of the consumer website SanrioTown.com was publicly accessible owing to a security vulnerability. The vulnerability has been corrected and investigations are underway. To our knowledge at this time, no personal information of SanrioTown.com users was stolen or exposed.

On December 19, it was revealed by security researcher Chris Vickery that personal information (such as names, date of birth, gender) belonging to SanrioTown.com members was accessible by someone who knew the IP addresses of specific vulnerable servers.

The vulnerable data did not include credit card information or other payment information. Users’ passwords were accessible but remained securely encrypted with the cryptographic hash function SHA-1.

Please note that membership data of SanrioTown is not shared with other Sanrio services or websites (such as Sanrio.com), therefore other Sanrio services were not affected by this security vulnerability.

We investigated the problem and applied fixes, including securing the servers identified as vulnerable by Mr Vickery.

We are conducting an internal investigation and security review into this incident; at this time we have no indication that users’ personal information was stolen by malicious parties.

Number of people whose personal information may have been leaked: Up to 3.3 million website members were potentially affected by this security vulnerability, however we have no indication that any user data was actually exposed or utilized by malicious parties
