Personal Data Including SMS and Calls of Mobile Loan App Users in China Left Open for All to See

Safety Detectives’ research team has recently discovered a sizeable data leak (over 899gb and growing by the day) of a China-based server, which has now been closed. We are unable to confirm the company behind the leak, but according to the data, it appears to most likely be a marketing agency for mobile apps. The provider of the server is Aliyun Computing Co., but they only rented the server to the company and are not otherwise involved or responsible for the leak.


What’s Being Leaked?


Led by Head of Research, Anurag Sen, our security research team has discovered a veritable treasure trove of data. With what seems to be data of more than 100 mostly loan-related apps, this is no insignificant breach of trust for the users of said applications. The Elastic server exposed publicly sensitive information of Chinese citizens.
