(Alliance News) - Engineering services provider James Fisher & Sons PLC on Tuesday said it was victim of a cyber attack.
James Fisher shares were 4.3% lower at 1,923.12 pence each in London on Tuesday afternoon, making it one of the worst performers in the FTSE 250 index.
The company said attackers tried to gain unauthorised access to its computer systems, but stopped short of providing specific details regarding the cyber attack.
James Fisher has appointed external specialists, including a forensic cyber security expert, to investigate the incident.
"As a precautionary measure James Fisher & Sons took all affected systems offline. This has restricted 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," James Fisher said.
"Work is ongoing to complete the recovery as quickly as possible and to minimise any impact on our businesses."
James Fisher provides services to the oil and gas, marine, defence and nuclear industries.
