LONDON (Reuters) - Insurers face potential multi-billion dollar claims for cyber attacks related to Russia's invasion of Ukraine, despite policy wording designed to get them off the hook for war, industry sources say.

Following the Feb. 24 attack on Ukraine and Western sanctions against Moscow, the U.S. government said last week it had seen "preparatory" Russian hacking activity aimed at numerous U.S. companies, though it said it had "no certainty" such an attack would occur.
