Hackers attacked a popular Chinese video-sharing site, breaching millions of private data including encrypted passwords, according to an emergency notice from the site on Wednesday.
AcFun, the site for the comics and games community, urged its users on Weibo to immediately change their passwords since "nearly 10 million users' data have been leaked, including user IDs, nicknames and passwords."
"We did not make AcFun safe enough, for which we sincerely apologize," the statement said.
The site has gathered evidence and reported the incident to the police.
A team of tech experts was formed to upgrade the site's security system, the statement said.
Many netizens said on Weibo that they received messages and emails from AcFun reminding them to change their passwords as of press time.
The Tencent-backed online short video start-up Kuaishou, which reportedly acquired AcFun earlier this month, said the company would offer financial and technical support to AcFun to ensure data safety and prevent such incidents from happening again, financial news site lanjinger.com reported.
Four months ago, online video platform Bilibili was also reportedly breached when its users found that they could log on 360 Kuaishipin, another video platform, using their Bilibili account information.
Bilibili denied in February any information leak.
