pcworld.com Domain Breach Exposure Report

The domain pcworld.com has experienced a high volume of data breach events, totaling 1877, and 310 active infostealer logs over the past year. The majority of these events, 85.8%, are historical data breaches, with 14.2% being current infostealer activity. The timeline indicates a significant spike in client-related events in March 2026, alongside a notable increase in employee-related events in January 2026. Malware families associated with these events include LummaC2, Redline, and Acreed, primarily targeting Windows 11 operating systems. The data suggests a substantial exposure through combolist sources (86.8%) and database dumps (13.2%), impacting 1762 clients and 425 employees. Given the high number of data breaches and active infostealer logs, this exposure presents a critical risk. The prevalence of infostealer malware and the reliance on combolist sources indicate a high likelihood of credential compromise for both employees and clients. Prioritization should focus on immediate remediation of identified vulnerabilities, enhanced credential monitoring, and user education to mitigate further compromise. The targeted services, particularly the e-commerce platform (shop.pcworld.com), are likely vectors for these attacks.
