the case is they're worrying about unintended consequences. a lot of ukrainian infrastructure will be part of a complex global supply chain. so when you attack ukrainians, it can spill over. we saw a shipping company. while there's no specific threat that's been identified for western businesses, those unintended consequences of a cyber attack are clear. onto the solutions really. what we're talking about are basic cybersecurity methods. you could argue it's a bit too late to be talking about it 24 hours after the invasion. we're talking about critical assets. segmenting. using two factor authentication. all of the good cybersecurity measures they apply now more than ever. >> james sullivan, thank you
