Edelson Lechtzin Investigates Class Action Following Ernst & Young Breach

Ernst & Young detected suspicious activity on its network on April 23, 2026, triggering an investigation that revealed an unauthorized third party had accessed a secondary IT management platform. This breach allowed intruders to download documents containing personal and financial data used for tax filings. While the firm has secured its systems and notified federal law enforcement, it has not disclosed the specific number of affected clients or the identity of the third-party vendor whose platform served as the entry point.

The exposure of such detailed tax information poses a significant risk for identity theft, tax fraud, and sophisticated phishing attempts. Edelson Lechtzin LLP is currently evaluating legal remedies for those impacted, offering free case consultations for individuals who received breach notifications. Attorneys advise affected parties to monitor credit reports, enroll in identity restoration services if provided by EY, and consider requesting an IRS Identity Protection PIN to mitigate the risk of fraudulent filings.
