promptfile.com Domain Breach Exposure Report

The domain promptfile.com is associated with a significant exposure event, primarily driven by 3,311 historical data breaches and 401 active infostealer logs. The data breaches are exclusively linked to "Combolist sources," indicating a high likelihood of credential stuffing attacks targeting users. The active infostealer logs are attributed to several malware families, with Redline, LummaC2, and Vidar being the most prevalent. The timeline shows a surge in client-related events, particularly in March 2026, coinciding with the highest number of data breaches and infostealer activity. The exposure primarily affects clients, with no employee-related events reported. The geographical distribution indicates a global impact, with the United States, Egypt, and Belgium showing the highest percentages of affected entities. Given the high volume of historical data breaches and active infostealer activity, promptfile.com represents a critical risk. The prevalence of known infostealer malware like Redline and LummaC2 suggests that user credentials may have been compromised and are actively being exploited. The focus for remediation should be on enhancing credential security, implementing robust monitoring for suspicious login activity, and potentially notifying affected clients about the risk of account compromise. Further investigation into the nature of the "Combolist sources" and the specific data compromised in the breaches is recommended.
