MDL 3159Data Privacy & Security

Keffer Development Services, LLC, Data Security Breach Litigation

The causation theory in data breach litigation involves establishing that the breach was a proximate cause of the harm. Exposure of PHI and PII can lead to identity theft and financial fraud through mechanisms such as unauthorized access and misuse of stolen data. Emotional distress arises from privacy invasion and the anxiety of potential misuse. Courts require concrete evidence linking the breach to specific harms, often scrutinizing whether the breach increased the risk of harm or directly caused the damages. Legal analyses emphasize that causation must be proven as a substantial factor, with courts cautious about speculative damages, especially in class actions.
