Researcher discovered database containing data of 3.3 million Hello Kitty fans

The researcher Chris Vickery has discovered a database leak that exposed 3.3 million accounts belonging to Hello Kitty fans.

The database of the official online community for Hello Kitty and other Sanrio characters, the, has suffered a data breach. The researcher Chris Vickery has discovered online a database exposing 3.3 million accounts belonging to Hello Kitty fans.

According to Vickery not only the primary database was affected, the fan portals of the following websites were also impacted by the leak:


On Saturday evening, Vickery reported the discovery to and Salted Hash.

The records exposed include first and last names, gender, encoded birthday (easily reversible), country, email addresses, SHA-1 hash passwords, password hint questions with corresponding answers, and other information.


The expert also discovered two additional backup servers containing mirrored data, then he notified the data leak to both Sanrio and the ISP being used to host the database.

This incident is raising great concern in the IT security industry because one again personal information of children are exposed online.

At the end of November, the VTech toy maker has been hacked exposing data of 11.6 million people, 6.4 million of them belonging to children.

The recent VTech data breach exposed 11.6 million people, and 6.4 million of them were children.

The identity theft of a child is even more insidious because crooks could abuse of the stolen data for years.

Every time I receive news of a data breach I suggest affected users to the change password for all the websites that share the same login credentials.

The same suggestion is valid for users that share the same hint question and answer across different websites.
