French classification society Bureau Veritas (BV) has gone semi-offline, slowing down its services, after a cyber-attack on its computing systems.
BV, which is one of the biggest class societies for shipping, said it detected an attack on its cybersecurity system on Saturday 20 November.
"In response, all the group's cybersecurity procedures were immediately activated," it said.
"A preventive decision has been made to temporarily take our servers and data offline to protect our clients and the company while further investigations and corrective measures are in progress," BV added.
