Executive Summary
A LexisNexis cloud-infrastructure breach (disclosed around 2026, attributed to the group FulcrumSec) exploited an unpatched AWS application (the React2Shell / CVE-2025-55182 vulnerability). Attackers claimed roughly 3.9 million records and ~400,000 cloud user profiles including names, phone numbers, email addresses, and business contact details. The dataset indexed here covers about 15,808 unique email addresses.
ObscureIQ assessment: Extremely high risk because the data is already normalized for discovery and linkage. Exposure enables profiling, stalking, executive targeting, identity theft, and cross-dataset correlation at scale.
Breach Impact
Exposure of business/user contact data for a risk-data provider supports targeted phishing of legal/government/enterprise users; the broader claimed set (incl. AWS secrets) raised significant supply-chain concern.
