Ernst & Young disclosed a data breach after an unauthorized third party accessed a third-party support ticket system used by its IT personnel and downloaded documents that may contain client tax, personal, and financial data. The exposure window ran from March 28 to April 12, with anomalous activity detected on April 23 and disclosure on July 17, 2026. EY says it secured the platform, removed the unauthorized access, and has no indication of misuse or further exposure. The leak matters because the compromised tickets may include sensitive records tied to tax filings and client identity data.
