(ECNS) - China's popular animation and video platform AcFun announced on Wednesday that hackers had compromised tens of millions of bits of user data, including user IDs, nicknames, and encrypted passwords.
AcFun, known among netizens as "Station A," urged users who hadn't logged in since July 7, 2017 to change their passwords on the platform as soon as possible, and also modify reused passwords for any other online accounts.
Users who had logged in since the date but used overly simple passwords were also advised to change to stronger ones, said the website.
The root cause of the hack was that the site was not secure enough, said AcFun, adding that a security team composed of internal and external technical experts was promptly assembled to upgrade security.
Evidence was collected and reported to police, AcFun said.
Prior to the hacking, online short video start-up Kuaishou, backed by internet giant Tencent, had just bought the platform. The platform would keep its independence in branding, operation and development, while Kuaishou would provide support in regard to capital, technology and other resources, according to AcFun.
