google.ch Domain Breach Exposure Report

The domain google.ch has experienced a significant number of historical data breaches (444) and active infostealer logs (120) over the past year, impacting 263 employees and 301 clients. The majority of these events, 78.7%, are attributed to historical data breaches, with a notable increase in employee and client-related incidents observed from September 2025 through April 2026. Malware families such as Redline and LummaC2 were identified, and the primary sources of exposure appear to be combolist sources (88.3%) and database dumps (11.7%). The affected operating system is predominantly Windows 11. Given the high volume of data breaches and the presence of infostealer activity, this exposure presents a critical risk. The prevalence of combolists suggests credential stuffing attacks are a primary vector. Remediation should focus on enhancing credential hygiene, implementing multi-factor authentication across all services, and conducting thorough security audits of systems associated with the identified malware families and data breach sources. Prioritize investigations into the specific data compromised in the 444 historical breaches and the active infostealer logs to understand the full scope of potential impact.
