GDPR Applies to U.S. Dark Web Investigators Handling EU Data

Summary

The article explains how GDPR may apply to U.S.-based investigators handling EU or UK breach data, and recommends documenting a lawful basis, screening sensitive data, minimizing retention, and clarifying controller roles.

Key points

• GDPR may apply to U.S.-based firms when their investigations involve EU or UK residents’ personal data, regardless of where the firm or its servers are located.
• Leaked credentials, device fingerprints, IP addresses, and other identifiers can remain personal data when investigators collect or analyze them.
• Special-category data, such as information about health, religion, or sexual orientation, requires extra scrutiny and may face stricter processing limits.
• The article recommends documenting the lawful basis for processing; EU investigations relying on legitimate interests require a necessity and balancing assessment.
• It says UK law now recognizes a defined legitimate-interests basis for certain purposes, including crime prevention, while EU processing still requires the full assessment.
• Investigators should minimize collected data, set deletion periods, and clarify controller and processor responsibilities in client agreements.
