If you have received a data breach notification letter, it confirms that your personal information was compromised in this incident.

Affected individuals may face increased vigilance against unauthorized account access, fraudulent applications opened in their name, or targeted phishing attempts designed to exploit their compromised data. Understanding these potential outcomes is crucial for protecting yourself.
