What happened?
In October 2015, the Chinese site known as NetEase (located at 163.com ) was reported as having suffered a data breach that impacted hundreds of millions of subscribers . Whilst there is evidence that the data itself is legitimate (multiple HIBP subscribers confirmed a password they use is in the data), due to the difficulty of emphatically verifying the Chinese breach it has been flagged as "unverified". The data in the breach contains email addresses and plain text passwords. Read more about Chinese data breaches in Have I Been Pwned.

Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Change exposed or reused passwords, begin with your email account, and turn on multi-factor authentication where available.
Treat unexpected breach follow-ups with caution. Do not use links or phone numbers in a suspicious message; contact the organization directly.
Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
