caijing.com.cn Domain Breach Exposure Report

The domain caijing.com.cn has experienced a significant number of data breach events, totaling 656 over the observed period, with an additional 170 active infostealer logs. The majority of these events are linked to "Combolist sources" (90.7%) and "Database dumps" (9.3%), indicating a high likelihood of credential compromise. Malware families such as LummaC2 (25.9%), Redline (14.7%), and Rhadamanthys (1.2%) were observed, suggesting active exploitation and data exfiltration attempts. The timeline shows a surge in employee and client-related events from September 2025 onwards, peaking in April 2026, with a notable increase in client-related incidents in March 2026. The affected operating systems are predominantly Windows 11 and Windows 10 Enterprise, with a small percentage of Windows 7 and Vista, suggesting a mix of modern and potentially legacy systems are at risk. Given the high volume of data breaches and active infostealer logs, this exposure presents a critical risk. The prevalence of combolist sources and database dumps points to widespread credential stuffing and potential account takeovers. The observed malware families are known for their ability to steal credentials and sensitive information. Prioritization should focus on immediate remediation of identified vulnerabilities, credential reset for affected employees and clients, and enhanced monitoring for suspicious activity. The primary focus should be on preventing further data exfiltration and mitigating the impact of compromised credentials.
