Understanding your Schiff and Associates CPA data breach notification letter

If a Schiff and Associates CPA letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.

Why you received this letter

As a prominent certified public accounting and advisory firm, Schiff and Associates CPA manages the intricate financial, tax, and corporate accounting needs of businesses and affluent individuals across New England. Because of the core nature of their operations, the firm routinely collects, processes, and stores vast repositories of deeply sensitive financial and personal documentation. Clients trust Schiff and Associates CPA with their most intimate records—ranging from corporate balance sheets and payroll histories to individual annual tax returns—making the firm a central repository for high-value financial data that commands a significant premium on illicit digital marketplaces. In 2026, Schiff and Associates CPA formally reported a major cybersecurity incident to the Office of the Massachusetts Attorney General, revealing that unauthorized actors had breached their internal digital infrastructure. While accounting firms are frequent targets for advanced cybercriminals due to the sheer concentration of monetizable documents, an incident of this magnitude typically involves unauthorized network intrusions, compromised employee credentials, or sophisticated ransomware deployments. Threat actors specifically target accounting firms to intercept tax season communications, infiltrate client portals, and exfiltrate confidential files stored across unsegmented internal networks and legacy databases. The breach exposed a staggering array of sensitive records, creating severe, lifelong risks of identity theft and financial fraud for affected individuals and corporate stakeholders. The compromised datasets characteristically include full names, Social Security numbers, dates of birth, detailed tax return information, wage and compensation records, and direct deposit account details. When Social Security numbers and detailed tax documents are exposed together, cybercriminals gain the exact leverage needed to file fraudulent tax returns for illicit refunds, hijack existing financial accounts, execute unauthorized wire transfers, and open lines of credit in victims' names without their knowledge or consent. Under both Massachusetts state data security regulations and federal standards enforced by the Federal Trade Commission, financial and professional services firms like Schiff and Associates CPA have an affirmative legal duty to implement and maintain robust administrative, physical, and technical safeguards to protect client data. This includes deploying multi-factor authentication, performing routine network vulnerability assessments, and maintaining encrypted data backups. The occurrence of a widespread data breach strongly indicates a failure of these foundational security obligations, demonstrating that the firm's protective measures were inadequate to repel foreseeable cyber threats. Receiving an official data breach notification letter from Schiff and Associates CPA is a formal admission by the firm that your confidential information was compromised due to their failure in data security. Legally, this notification establishes the necessary standing to participate in a class action lawsuit aimed at holding the firm accountable for negligence and securing compensation for your increased risk of identity theft. Our class action firm is investigating this breach on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf.

What to do after the letter

  1. Confirm the notice is genuine

    A legitimate Schiff and Associates CPA notice references the specific incident reported to the Massachusetts Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.

  2. Keep the letter — it is your proof of connection

    The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.

  3. Protect your accounts and credit

    Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.

  4. Find out whether you have a claim

    Whether the Schiff and Associates CPA breach gives you a legal claim depends on the facts. A free, no-obligation case review will tell you where you stand — there is no cost and no commitment to find out.
