7k7k Data Breach (2011)
In approximately 2011, it's alleged that the Chinese gaming site known as 7k7k suffered a data breach that impacted 9.1 million subscribers. Whilst there is evidence that the data is legitimate, due to the difficulty of emphatically verifying the Chinese breach it has been flagged as "unverified". The data in the breach contains usernames, email addresses and plain text passwords. Read more about Chinese data breaches in Have I Been Pwned.
