Deloitte said it immediately contacted government authorities and the affected clients after discovering the hack, which stemmed from a breach in an email platform, the firm said in a statement.
“Only very few clients were impacted,” the company said. “No disruption has occurred to client business, to Deloitte’s ability to continue to serve, or to consumers.”
“Deloitte remains deeply committed to ensuring that its cyber-security defenses are best in class, to investing heavily in protecting confidential information and to continually reviewing and enhancing cyber security,” the company said.
The Guardian reported Monday that six Deloitte clients had information breached by a sophisticated attack and hackers potentially had access to usernames, passwords, IP addresses, architectural diagrams for business.
