A massive dataset from Domains-Monitor was exposed containing a comprehensive list of registered internet domain names. The collection represents a snapshot of the global web infrastructure gathered through monitoring services. The incident involved the extraction of 275 million unique URL records. While the data primarily consists of domain addresses rather than personal user credentials, the scale of the collection makes it a significant resource for network mapping and cybersecurity research. The data was reportedly obtained through a download of the services internal tracking tables in mid-2025.
