BEIJING—Sina Corp. issued an apology to users of its Weibo service after it
was hit by a virus, in what appeared to be the first attack of its kind aga
inst the popular Chinese microblogging service.
The attack began around 8:20 p.m. Tuesday when malicious links advertising v
ideos, updates on scandals and other eye-catching content began appearing on
Weibo, a Twitter-like service that had more than 140 million users as of Ma
rch. The virus infected the account of any user who clicked on one of the li
nks, prompting it to send out links to the user's followers.
"We deeply regret the inconvenience experienced by some users" as a result o
f the attack, Sina said in a statement posted Wednesday on the company's web
site.
Local media reports estimated the number of accounts infected at between 30,
000 and 32,000.
Sina Weibo spokesman Mao Taotao said the company had yet to determine the nu
mber of infected accounts.
Sina said the attack, which exploited "leaks" in a couple of Sina Weibo web
pages, had been brought under control by 9:25 p.m. Tuesday. "Users' password
s and other personal information won't be affected," the company said.
The attack comes as rivals, including Chinese Internet giant Tencent Holding
s Ltd., are challenging Sina's dominance of the country's fast-growing micro
blogging market.
Shanghai-based research firm RedTech Advisors LLC estimated that Sina Weibo
has 57% of China's microblog users and accounts for 87% of the country's mic
roblog activity.
It wasn't clear who launched the attack, or why.
Sina said it had collected evidence and handed it over to the authorities.
"We will absorb this lesson and perfect all manner of relevant measures to e
nsure the safety of the Weibo platform and users' information," said the com
pany, which is listed on the Nasdaq Stock Market.
