Executive Summary
In approximately December 2011, the Chinese casual-gaming portal 7k7k (7k7k.com) allegedly suffered a data breach impacting ~9.1 million subscribers, exposing usernames, email addresses, and plaintext passwords. It was part of a broader wave of attacks on Chinese portals (CSDN, 17173, 178.com). Have I Been Pwned lists it as unverified. Plaintext passwords make the credentials immediately usable for credential stuffing.
ObscureIQ assessment: Exposure enables account takeover, phishing, and harassment. Gaming-platform data can also support cross-platform identity linkage, especially for younger users.
Breach Impact
Because passwords were stored in plaintext, the exposure of usernames, emails, and passwords enables immediate credential-stuffing and account-takeover where users reused credentials, plus targeted phishing. Authenticity is unverified.
