An unauthorized party accessed the platform between March 28 and April 12, downloading documents that may contain personal and financial tax information. EY detected the anomalous activity on April 23, engaged external cybersecurity experts, and has since secured its systems and notified federal law enforcement. The exact number of affected clients and the specific data types exposed have not been disclosed. Affected clients are being offered 24 months of identity monitoring through Experian, with enrollment required by October 31, 2026. No ransomware or extortion group has claimed responsibility. ## Full article daily.dev links to this article rather than hosting it.
