Alipay.com

In late 2011 and early 2012 reports surfaced regarding a historical data security incident involving Alipay the major Chinese payment platform. Investigations revealed that former employees had illegally downloaded and sold customer information from the internal database. The compromised data primarily included sensitive user details and transaction history metadata. While the core financial systems remained secure the breach highlighted significant internal security risks and led to a major overhaul of data access policies within the Alibaba Group to prevent similar unauthorized exports of user records.
