More frequent extreme weather events, like hurricanes and tsunamis, will put critical digital systems in greater physical danger, such as damaging underwater communication cables and off-site servers. The resulting disruption to internet connectivity puts systems at greater risk of attacks, said Messaghi, and this has already been demonstrated with events like Hurricane Sandy.
