Ernst & Young data breach claimed by ShinyHunters extortion gang

Ernst & Young disclosed that a third‑party IT support ticketing system was compromised and documents potentially containing client tax and financial information were stolen after unauthorized access between March 28 and April 12; the ShinyHunters extortion group later claimed responsibility on its data leak site, alleging a supply‑chain compromise and access to EY credentials and environments, though these claims remain unverified.
