OR WAIT null SECS
20 or more American companies working in liquefied natural gas (LNG) production suffered cyberattacks in February right before the Russian invasion of Ukraine. These included Chevron and Cheniere Energy. The U.S. Cybersecurity and Infrastructure Security Agency is ascertaining whether Russia was the source of the attacks. But the current view is that Russia was the likely source in an effort to destabilize the U.S. energy industry.
With Russian oil imports now banned, such attacks may well recur or even ramp up.
State-sponsored cyberattacks are a serious business. Russia is suspected of bringing down Ukrainian defense and financial websites as part of its invasion strategy.
