asahi.com Domain Breach Exposure Report

The telemetry indicates a significant exposure event impacting asahi.com, with a high risk score of 97. The primary concern stems from 11,396 historical data breaches and 2,313 active infostealer logs, affecting a substantial number of clients (12,399) and employees (1310) over the period of July 2025 to June 2026. Malware families such as Vidar, LummaC2, and Rhadamanthys are prominently featured, suggesting a focus on credential harvesting and data exfiltration. The data suggests that "Combolist sources" are the predominant source of leaked data, accounting for 97.5% of identified leaks, with targeted services including "digital.asahi.com" and its associated login and user profile endpoints. Given the high volume of data breaches and active infostealer activity, this situation presents a critical risk. The prevalence of infostealer malware targeting client and employee credentials, coupled with the large number of historical data breaches originating from combolists, indicates a high likelihood of account compromise and potential financial or reputational damage. Prioritization should focus on immediate incident response, including credential rotation for all affected users, enhanced monitoring for suspicious activity on "digital.asahi.com" and related services, and a thorough investigation into the root cause of the historical data breaches to prevent recurrence.
