Executive Summary
A dataset attributed to the Chinese gaming portal uuu9.com, surfacing in September 2016, contains about 7.5 million accounts. The HIBP parse lists email addresses and usernames; some secondary sources additionally claim plaintext passwords and larger counts. HIBP lists the breach as unverified.
