When personal information is exposed in a data breach, it can create significant concerns for those affected. The compromise of your data means you may face an increased risk of targeted phishing attempts, identity theft, or financial fraud. While specific details about the exposed information are not yet public, any breach of personal data demands vigilance.

If you received a notification letter from Hennessy Advisors, it is important to act promptly. Review any provided guidance carefully and consider monitoring your financial accounts and credit reports for suspicious activity. Changing passwords for online accounts, especially if you reuse them across multiple services, is also a recommended practice.
