Tencent QQ 690M Phone-to-Account Mapping Data Leak Data Breach
Surfacing initially in 2020 and widely circulated under the designation "6.9更新总库", a massive data collection originating from the instant messaging and social network Tencent QQ (qq.com), operated by Tencent Holdings, was distributed across cybercrime networks.
Exposed Data Types
2- Usernames
- Phone numbers
About This Breach
The exposed archive contains approximately 690,000,000 user correlation records. Each entry establishes a direct link between a user's unique numeric QQ identification handle and their active, 11-digit mobile telephone number.
Because mobile telephone numbers in mainland China require strict real-name identity registration, the public de-anonymization of 690 million QQ accounts strips user pseudonymity and facilitates mass profiling, surveillance reconnaissance, and targeted smishing campaigns.
