UK shipping group James Fisher has been hit by a cyber attack that saw hackers gain unauthourised access to its computer systems.
The London-listed tanker owner said it took immediate steps to respond to and manage the incident, appointing external specialists, including forensic cyber security experts to investigate the circumstances and scope of the incident.
"These investigations are ongoing," it added.
As a precautionary measure, it took all affected systems offline, restricting its access to communication and financial systems.
"Following containment of the incident, we are working with our cyber security experts on a safe recovery of systems, applications and data from our disaster recovery back-up," the company said.
Work ongoing
"Work is ongoing to complete the recovery as quickly as possible and to minimise any impact on our businesses."
Fisher also said it had notified regulators and law enforcement agencies in the UK.
It provided no further details, but said an update would follow.
The company has been contacted for more information.
Shipping has been the target of numerous cyber attacks, with the most high profile probably being that against Maersk in 2017.
The Danish group's port and shipping operations were severely disrupted by a NotPetya raid which cost the company $300m and hit operations for two weeks.
