Timely detection and notification are critical responsibilities for organizations holding sensitive data.

Recipients of the breach notice are encouraged to remain vigilant. Review all financial statements and credit reports for any suspicious activity. Consider placing a fraud alert or security freeze on your credit files to prevent new accounts from being opened in your name. Follow any specific recommendations provided in the official notification letter.
