Meituan Dianping, the internet giant backed by China’s most valuable tech corporation, has faced a data breach that exposed the private information of tens of thousands of users. The potential breach comes as revelations about leaks at Facebook spur a regulatory and consumer backlash against internet companies around the globe. In Meituan’s case, allegedly tens of thousands of data snippets, everything from names and mobile numbers to home addresses, on food-delivery customers went on sale online for as little as 0.1 yuan (2 US cents) per item. Because of the multiple parties involved in food delivery, such as merchants and third-party delivery services, some unlawful participants might have been able to gain access to information.
