familydoctor.com.cn Domain Breach Exposure Report

The domain familydoctor.com.cn has experienced a significant number of data breaches, totaling 258 events, with an additional 85 infostealer events observed. The majority of these exposures, 75.2%, are attributed to historical data breaches, while 24.8% are active infostealer logs. The timeline indicates a surge in client-related exposures starting in September 2025 and peaking in April 2026, with employee exposures also increasing notably from January 2026 onwards. Malware families such as Redline and LummaC2 were identified, and the primary leak sources are combolist sources (95.7%) and database dumps (4.3%). The high volume of data breaches and active infostealer logs, affecting a large number of clients and employees, presents a critical risk. The prevalence of combolist sources suggests compromised credentials are being widely distributed, potentially leading to further account takeovers and sensitive data exfiltration. Remediation should focus on credential hygiene, including mandatory password resets, multi-factor authentication implementation, and enhanced monitoring for suspicious login activity across all services, particularly those related to authentication like /logon and /login.
