Mop.com

Mop.com, one of the most famous and oldest Chinese social entertainment forums, suffered a massive data breach involving millions of user accounts. The leak originated from an older database backup and became widely circulated in the darknet community. The exposed data includes sensitive user credentials such as usernames and hashed passwords along with email addresses. This incident is part of a broader trend where legacy Chinese web platforms were targeted due to outdated security protocols and insufficient encryption methods used during the early 2010s.
