US has 'significant' cyber vulnerabilities, but a sweeping Russian cyberattack is unlikely
CNN
In the winter of 2015, computer hackers working for the Russian government attacked Ukraine's power grid and switched off the lights and heat to more than 200,000 consumers.
Last year, a cybercriminal group with operatives in Russia launched a successful ransomware attack on a key East Coast pipeline that forced the company, Colonial Pipeline, to temporarily close the spigot and pay 75 bitcoins -- or $4.4 million -- to bring it back online. It was the largest cyberattack on an oil facility in US history.
And it was a Russian government lab that built tools used in one of the most dangerous cyber offensives in the history of the digital age, penetrating the control systems of a Saudi petrochemical plant in 2017 for the purpose of setting off an explosion that, had it succeeded, could have killed people.

The White House is making clear it views President Donald Trump’s Friday Oval Office showdown with Ukrainian President Volodymyr Zelensky as an overwhelming win underscoring Trump’s “America First” leadership, dispatching top officials and allies on the airwaves to amplify Trump’s handling of the situation even as European leaders are putting on a key show of force of unity for Ukraine and its leader.
