Baihe.com

In 2011 the Chinese matchmaking and dating service Baihe experienced a major security breach. An unauthorized party managed to compromise the database resulting in the exposure of approximately 20 million user records. The leaked data was found across several tables and included sensitive personal information such as usernames, email addresses, phone numbers, IP addresses, and passwords stored as MD5 hashes. This incident significantly impacted the privacy of millions of users in China during a period of rapid growth for online dating platforms in the region.
