Deloitte has been hit by a cyber attack in which information relating to clients was breached by hackers, it's been revealed.
The professional services giant - one of the so called top four in the world - said a breach had occurred where an attacker had accessed data from an email platform.
"Very few" clients have been affected by the attack it has been determined, following a review by cyber security and other experts both within the company and from outside. All have been contacted and none have been disrupted as a result of the attack and neither has Deloitte's own business.
The firm has informed regulators about the incident, first reported by The Guardian. The attack was discovered earlier this year, according to the report.
"Deloitte remains deeply committed to ensuring that its cyber-security defences are best in class, to investing heavily in protecting confidential information and to continually reviewing and enhancing cyber security," a spokesperson said.
