Hallisey & D'Agostino Data Breach Exposes Client Information

Hallisey & D'Agostino, LLP, a Vermont-based professional services firm specializing in legal representation and advisory services, recently reported a data security incident to the Vermont Attorney General on April 18, 2026. Given the firm's role in handling confidential client matters, the data entrusted to them is inherently sensitive and highly valuable to malicious actors. The firm routinely collects, processes, and stores vast quantities of confidential client files and personally identifiable information.

The breach exposed a broad spectrum of sensitive personal data. Compromised categories include Full Name, Social Security Number, Date of Birth, Home Address, Financial Account Details, Tax Return Information, Legal Correspondence and Case Files, Direct Deposit Information, and Phone Number and Email Address. The exposure of such extensive data can lead to severe consequences for affected individuals.

The compromise of your Social Security Number, Financial Account Details, and Direct Deposit Information places you at elevated risk for identity theft, financial fraud, and unauthorized account access. Furthermore, the exposure of your Legal Correspondence and Case Files, coupled with Tax Return Information, could lead to targeted scams, privacy violations, or extortion attempts, making it imperative to take proactive steps to protect yourself.

As a professional entity entrusted with confidential records, Hallisey & D'Agostino, LLP had a clear legal and ethical obligation to implement robust security measures to safeguard this sensitive information. A data breach of this magnitude suggests a potential failure to maintain adequate cybersecurity protocols, leaving client data vulnerable. Under Vermont state laws and common law duties, firms are expected to protect the data in their custody.
