(Yicai Global) June 14 -- Hackers have stolen nearly 10 million items of user data from Chinese anime barrage video platform AcFun. The firm, which recently changed owners, has admitted the security measures were insufficient.

The leaked data includes user IDs, nicknames, and encrypted passwords. The Beijing-based company has sent reminders to users to change their passwords and posted related alerts on its website and social media accounts, the Beijing News reported.

AcFun has already stepped up its security so if users log in now, their data will be automatically hidden by a better protocol. Still, those who have simple passwords should change them just in case.

Users should also modify the keys to accounts on other platforms if those use the same passwords or nicknames, reminded security expert Tian Jiyun.

Kuaishou Technology, AcFun's parent company said it is very concerned about the data hack's impact on users. Kuaishou will provide technical and capital support to AcFun to help it enhance user data security to avoid similar incidents, the Tencent-backed video streaming parent firm said in a statement.

Major short-video streamer Kuaishou bought AcFun early this month to enrich its fanbase at an estimated price of CNY1.03 billion (USD162 million). Both firms have been targets of this year's government crackdown on internet sleaze.
