Hello Kitty community leaks details of 3.3m users

Parents have been warned of another children-focused website that has suffered a serious breach of customer’s private data. The recent victim is the online community for Hello Kitty fans and it is believed to have leaked details of over 3 million users.

Alarmingly, it seems to be data similar to the recent VTech breach, which also revealed usernames, first and second names, gender, country of origin and email addresses.

Sanrio, the owner of the brand based on the popular character, has not publicly responded to the allegations of an account leak.

Emily Orton, Director at Darktrace commented: "Companies like Sanrio need to urgently rethink the ways that they protect their information and reputation. The status quo of security is not good enough anymore – we know that companies face continual threat. Now it is time to do something about it, and bolster internal monitoring systems that work to catch early signs of compromise.”
