Mercadien P.C., CPAs, a prominent accounting and business advisory firm, recently reported a data security incident to the New Hampshire Attorney General. If you received a notification letter from Mercadien, it means your personal information may have been exposed due to this event.

Accounting firms like Mercadien handle a wide array of sensitive personal information. While the specifics of the data involved in this particular incident are still under investigation, the nature of their business means the compromise of such data can lead to serious concerns about potential identity theft and financial fraud. Your notification letter is a formal alert about this risk.

The first step after receiving a data breach notification is to take it seriously. Carefully review the letter for any specific advice or services Mercadien P.C., CPAs might be offering, such as credit monitoring. Even without specific data types named, it is wise to be extra vigilant about unsolicited communications, financial statements, and any requests for personal details.

Consider placing a fraud alert on your credit files with the three major credit bureaus (Experian, Equifax, TransUnion). This makes it harder for identity thieves to open new accounts in your name. Regularly monitor your bank statements, credit card accounts, and explanations of benefits for any unusual activity. Report anything suspicious immediately to your financial institution.

Data breaches can lead to long-term risks. Receiving a notification letter indicates that your personal information was potentially compromised. Understanding your rights and options is important. If you are concerned about how this incident might affect you, it can be helpful to discuss your situation with a legal professional.
