Chiesi USA Inc. Files NH Data Breach Report Amid Ongoing Investigation

Chiesi USA Inc. has filed a data breach notification with the New Hampshire Attorney General's office, acknowledging an incident that may have exposed personal information. The report, submitted on December 22, 2025, notes that the company is actively investigating the scope and nature of the breach.

The official filing does not specify the types of personal information involved in this incident, nor does it detail the number of individuals potentially affected. The exact date of the breach is also not publicly available in this record. Recipients of a direct notification from Chiesi USA Inc. should refer to that communication for any additional context the company may provide.

Because the precise categories of data involved remain unspecified, individuals should exercise general vigilance. This includes carefully monitoring financial account statements, credit reports, and any correspondence that appears suspicious. Be wary of unsolicited communications, whether by email, phone, or mail, asking for personal details.

As a general precaution against potential misuse of your data, consider placing a fraud alert or credit freeze on your credit files with the three major credit bureaus (Equifax, Experian, and TransUnion). These measures can help prevent unauthorized parties from opening new accounts in your name. Remain alert to any unusual activity and report it promptly to the relevant institutions.
