uuu9 Breach

In September 2016, UUU9.com, a prominent Chinese gaming website, reportedly experienced a data breach that exposed approximately 7.5 million user accounts. The compromised data included email addresses, usernames, and passwords.
Specific details regarding the perpetrators behind the breach and the exact methods employed remain unclear. The breach was traced back to a vulnerability in the UUU9 website, which allowed attackers to access the database remotely. ​
Due to challenges in verifying breaches originating from Chinese websites, the legitimacy of the data remains unconfirmed.
