Ernst & Young data breach claimed by ShinyHunters extortion gang

ShinyHunters, an extortion gang, claimed responsibility for a recently disclosed Ernst & Young data breach, stating it obtained system credentials through a supply-chain attack. The breach highlights risks in third-party access and authentication controls at a major professional services firm.

Why it matters: Enterprises and clients of Ernst & Young should assess whether their data was exposed and review access logs for unauthorized activity; practitioners need to evaluate supply-chain security and credential management in their own vendor ecosystems.
