Offshore and marine firm ES Group (Holdings) was hit by a ransomware attack, compromising encrypted information.

In its announcement on Jan 5, the company says the incident impacted the "majority" of its data in its servers but that citing "ongoing investigations" the "threat has been contained".

Thus far, there has been no significant impact on its business and operations arising from the incident, and its business and operations continue to be operational as usual, says ES Group.

The company adds that it has activated its business continuity plan and has taken actions such as disconnecting its systems from the network, engaging external help to assist with the investigations, as well as containment, remedial and data recovery efforts.
