Editorial & sourcing policy
Recent Breaches is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data, and we do not hold the data claimed in leak-site listings. Incidents are compiled from publicly accessible sources and threat-intelligence platforms and are reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — write to support@galaxywarden.com or press@recentbreaches.com.
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised. Recent Breaches and GalaxyWarden are independent and are not affiliated with, and do not endorse, any company or group named on this page. This information is aggregated from public sources for awareness only and is not legal, security, or investment advice.
