harpersbazaar.com Domain Breach Exposure Report

The domain harpersbazaar.com has experienced a significant number of data breaches, totaling 353 events, which constitute 81.1% of all recorded events. Additionally, there were 82 instances of active infostealer logs, representing 18.9% of events. The timeline indicates a notable increase in both employee and client-related events starting in late 2025 and peaking in April 2026, with 45 employee and 86 client events recorded in that month. Malware families such as Redline and LummaC2 were observed, and targeted services include various pages on harpersbazaar.com, particularly login and logon endpoints. The majority of data exposure originated from combolist sources (95.8%). Given the high volume of data breaches and the presence of infostealer logs targeting login pages, this exposure presents a critical risk. The data suggests a potential for widespread credential compromise affecting both employees and clients, with a clear upward trend in activity over the past year. Prioritization should focus on immediate remediation of identified vulnerabilities, particularly those related to authentication mechanisms, and a thorough investigation into the source and scope of the data breaches and infostealer activity. The prevalence of Windows 11 and Windows Server operating systems in the telemetry suggests that these platforms are primary targets.
