In October 2026, notifications sent out in recent weeks revealed that clients of Goldman Sachs' wealth management division and UK-listed hedge fund Man Group were among the victims of a data breach at accounting firm EY. The breach stemmed from a hacking incident in March and April that EY first disclosed in July. It originated from a vulnerability in Checkmarx software, which affected EY, several clients and many other organisations.
