mama.cn Domain Breach Exposure Report

The domain mama.cn exhibits a high-risk score of 80, primarily driven by a significant volume of historical data breaches (784 events) and active infostealer logs (115 events) observed between July 2025 and June 2026. The data breaches predominantly originate from combolist sources, suggesting compromised credentials. Infostealer activity is linked to malware families such as Redline and LummaC2, indicating potential credential harvesting. The exposure affects a substantial number of clients (712) and employees (187), with a notable increase in client-related events in April 2026. Targeted services include various subdomains of mama.cn, particularly related to passport and login functionalities, and also Jira (Atlassian). The high prevalence of data breaches and infostealer activity poses a significant risk of unauthorized access and further compromise. The timeline shows a surge in both employee and client-related events in early to mid-2026, highlighting an ongoing and escalating threat. Remediation efforts should focus on credential hygiene, including mandatory password resets for all affected employees and clients, enhanced monitoring of authentication logs for suspicious activity, and a review of access controls for critical services like Jira. Given the nature of the targeted services and the domain itself, the most appropriate industry sector is Technology & SaaS.
