First Circuit Affirms Dismissal of Data Breach Class Action for Lack of Traceable Injury

Short summary

The First Circuit affirmed dismissal of a data breach class action against Bayamón Medical Center, holding that the plaintiff failed to establish that her identity theft injuries were traceable to the hospital's 2019 ransomware attack. The ruling emphasizes that temporal proximity alone doesn't establish causation—plaintiffs must plead specific factual allegations connecting the compromised data to alleged misuse. The decision reinforces a key defense principle: standing in data breach litigation requires proving both concrete injury and traceability to the defendant's conduct.

• •Court dismissed breach class action due to lack of traceability between attack and claimed injury
• •Temporal proximity insufficient—must plead facts linking specific compromised data to alleged misuse
