Goldman Sachs, Man Group Hit by EY Data Breach

The notable point is not the breach itself but the vector: an audit and advisory intermediary, not the banks. That puts a third party inside the perimeter of large financial institutions, where confidential client material routinely sits. The disclosure names the affected firms but not the scope, so the practical question is whether this is a narrow incident or a pattern of exposure across EY's client base. Whether regulators or the firms themselves add detail is the open question.
