modcloth.com Domain Breach Exposure Report

The telemetry indicates a significant exposure event for modcloth.com, with 92% of observed events classified as historical data breaches and 8% as active infostealer logs. A total of 8427 data breaches and 734 infostealer events were recorded over the reporting period. The timeline shows a surge in client-related events in August 2025 and March 2026, and employee-related events peaking in January 2026. Malware families associated with these events include Redline, Rhadamanthys, and X-Files, commonly used for credential theft and data exfiltration. The majority of leak repository data originates from combolist sources, suggesting compromised credentials are a primary vector. Given the high volume of data breaches and active infostealer logs, this poses a critical risk to both employees and clients. The prevalence of credential-stealing malware and combolists indicates a high likelihood of account compromise and potential financial fraud or identity theft. Remediation efforts should focus on immediate credential resets for all affected employees and clients, enhanced monitoring for suspicious login activity, and a review of authentication mechanisms to prevent further credential stuffing attacks. The presence of infostealer malware also necessitates endpoint security reviews and user education on phishing and malware threats.
