The insurance giant had shut down its markets as a “precautionary measure” during the probe.

Lloyd’s of London said on Monday that its investigation into a possible cyberattack had found no evidence of data compromise, according to a report in Reuters.

“The investigation has concluded that no evidence of any compromise was found and as such Lloyd’s has been advised that its network services can now be restored,” a company spokesperson said in an email.

Lloyd’s refuses to speculate on source of the attack

Around 100 insurance syndicates operate at Lloyd’s. Last week the company issued an alert via email. “Lloyd’s has detected unusual activity on its network and we are investigating the issue,” they said, adding that the market was resetting the network.

“All external connectivity has been turned off, including Lloyd’s delegated authority platforms”, a Lloyd’s spokesperson told The Record. “We have informed market participants and relevant parties, and we will provide more information once our investigations have concluded.”

Back in June, Lloyd’s of London announced that it was cooperating with British and international governments to impose sanctions against Russia. A coordinated ban by Britain and the European Union prohibited insuring ships carrying Russian oil. Lloyd’s declined to comment on the possible source of the attack.
