Chinese hotel guests bare all

Website chakaifang.info, now dark, displayed confidential details about room bookings throughout China.

“Those of you who aren’t married, don’t access this site!” one Internet user wrote after visiting the Web page. “Those who are, try to avoid checking.”

Apparently hackers gained access to the thousands of records through a security loophole in a database belonging to CNWisdom, which bills itself as the country’s largest wireless internet provider for hotels.

“Soon, a seller on Taobao, China’s largest e-shopping website, offered eight gigabytes of hotel guest data for sale for 2,000 yuan. The Taobao shop has since been closed,” the South China Morning Post reports.

Chakaifang.info was blocked sometime between Sunday night and Monday morning, heightening tensions over online privacy in China.

It is unclear who ran the data dump site. The Web address is registered to a delivery company in Xinghua, Jiangsu province. A woman reached at the company denied any knowledge of the website.

CNWisdom serviced 450,000 hotel rooms in more than 4,500 hotels, as of 2011, the last time the company updated its figures. Guests had to register their personal data, including address, phone number, ID card, date of birth and workplace, to access the company’s Wi-Fi.
