Deloitte, known popularly in the United States as one of the "Big Four" accounting firms, has confirmed that it was the victim of a cyber attack. Not all of the details have been made public, but a Deloitte spokesperson noted that the attacker accessed data from an email platform.
According to the spokesperson, a review of the email platform is now complete. Their findings? While the company didn't provide specific information, the spokesperson did say that, "Importantly, the review enabled us to understand precisely what information was at risk and what the hacker actually did and to determine that only very few clients were impacted and no disruption has occurred to client businesses, to Deloitte’s ability to continue to serve clients, or to consumers."
