A Russian national found guilty of hacking into corporate earnings databases to steal and trade on nonpublic information about companies like Tesla and Roku was sentenced Thursday to nine years in prison.

The sentence for Vladislav Klyushin, handed down by a federal judge in Boston, adds to the U.S. government’s roster of Russian nationals in its possession as U.S. officials seek potential bargaining chips in a negotiated prisoner swap with Moscow for Americans, including the detained Wall Street Journal reporter Evan Gershkovich.

The U.S. Department of Energy got ransom requests from the Russia-linked extortion group Cl0p at both its nuclear waste facility and scientific education facility that were recently hit in a global hacking campaign, a spokesperson said on Friday.

The DOE contractor Oak Ridge Associated Universities and the Waste Isolation Pilot Plant, the New Mexico-based facility for disposal of defense-related radioactive nuclear waste, were hit in the attack, which was first reported on Thursday.

Ransomware attacks are increasingly targeting companies’ computer systems, demanding money in exchange for returning access and data.

Last month, hackers breached Colonial Pipeline — which supplies 100 million gallons of fuel daily along a 5,500-mile pipeline — and gained access to its business networks. In response, Colonial shut down pipeline operations, which led to nearly a week of widespread fuel shortages along the East Coast.

The Biden administration wants a more stable and predictable relationship with Russia. Russian President Vladimir Putin wants to show that his country is taken seriously as a world power. That is the backdrop for the first summit between the U.S. and Russian presidents, which will take place in Geneva on June 16.

"Russia is quite invested in having a very friction-filled rather than friction-free relationship with the United States," warns Fiona Hill of the Brookings Institution.

President Joe Biden has bluntly called Vladimir Putin a "killer" and said he "doesn't have a soul."

While he may have used robust language in the past, he is playing his cards closer to his chest ahead of the showdown with his Russian counterpart in an 18th-century Swiss villa overlooking Lake Geneva.

Landing in the U.K. last week, Biden told cheering throngs of U.S. Air Force personnel he planned to “meet with Mr. Putin to let him know what I want him to know.”

President Joe Biden frequently talks about what he sees as central in executing effective foreign policy: building personal relationships.

But unlike his four most recent White House predecessors, who made an effort to build a measure of rapport with Vladimir Putin, Biden has made clear that the virtue of fusing a personal connection might have its limits when it comes to the Russian leader.

Thousands of threatening messages that were sent to U.S. District Judge James Robart during Donald Trump's presidency came from Russia, according to CBS.

Robart, who temporarily blocked Trump's travel ban on predominantly Muslim countries, received numerous online death threats and criticisms after Trump tweeted a series of attacks against him in 2017.

In an interview with CBS' 60 Minutes airing Sunday, Robart discusses those threats and additional safety matters that federal judges face.

Hackers have reportedly breached the U.S. government agency responsible for maintaining the nation’s stockpile of nuclear weapons, according to news reports and government officials.
